Zakaj zaslon mojega avtoradia ne deluje? 5 načinov, kako to popraviti
Fantastično je imeti v avtu vrhunski model avtoradia z digitalnim zaslonom. Ogledate si lahko vse informacije, ki jih potrebujete glede glasbe, ki jo poslušate, navigacijske poti, ki ji morate slediti, in več.
Težava nastopi, ko ti fantastični kosi tehnologije preprosto prenehajo delovati. Preberite, če želite izvedeti, zakaj in kako to popraviti.
Na splošno velja, da zaslon vašega avtoradia ne bo deloval, če naleti na različne težave, kot je pregorela varovalka, zmanjšan zatemnilnik ali okvarjena žica za osvetlitev. Priključki med LCD-zaslonom in radijsko enoto so lahko mokri ali okvarjeni ali pa so pokvarjeni osvetlitev ozadja, LCD ali radijska enota.
Poglejmo, zakaj zaslon vašega avtoradia ne deluje in vse možne razloge, ki bi lahko vplivali na to. Ti razlogi niso vedno tako strašni, kot si mislite, in večino jih je mogoče pozdraviti z malo truda.
Pregled zaslona avtoradia
Danes so avtomobilski radijski sprejemniki z velikimi koraki napredovali od težkih, mehanskih in ročnih radijskih sprejemnikov iz petdesetih let prejšnjega stoletja, ki so ponujali samo AM//FM stereo z gumboma za frekvenco in glasnost.
Dandanes se večina glavnih enot skoraj zdi, kot da bi lahko izstrelili raketo v vesolje z odličnimi informacijsko-razvedrilnimi sistemi, ki imajo digitalne zaslone, glasovno upravljanje, brezžično zmožnost, navigacijo, iskanje območij zanimanja, pretakanje iz omrežja in drugo.
Vendar pa obstaja opozorilo, ko gre za to fantastično tehnologijo. Ker vse temelji na računalnikih in vezjih, obstaja veliko več prostora za pojav napak in okvar.
Zakaj zaslon mojega avtoradia ne deluje?
Če se znajdete v težkem položaju, ko zaslon vašega avtoradia ne deluje, se morda počutite nekoliko nesposobni pri soočanju s situacijo; vendar je le peščica spremenljivk lahko napačna.
Najprej si oglejmo najpogostejšo težavo, s katero se srečujejo avtoradio naprave, ko se ne vklopijo, nato pa bomo preučili ustrezno rešitev.
Kaj je glavni razlog, da se zaslon avtoradia ne vklopi?
To pomeni, da če gre kaj narobe (na primer kratki stik z ozemljitvijo), bo namenska varovalka prevzela glavno škodo in upamo, da bo pregorela, preden lahko povzroči kakršno koli resno škodo vašemu avtomobilu ali kateri koli opremi, na katero je bilo priključeno vezje.
Če tega še niste domnevali, bo to en popravek, ki ga lahko uporabite za avtoradio in lahko povzroči, da se zaslon ne vklopi, in to bom podrobno razložil spodaj.
Drugi razlogi, zakaj zaslon mojega avtoradia ne deluje
Ko pregori varovalka, ne deluje le zaslon, tudi celoten radio ne deluje. Če pa vaš radio deluje, vendar zaslon ostaja prazen, boste morali upoštevati nekaj drugih dejavnikov, ko boste ugotavljali, zakaj zaslon vašega avtoradio ne deluje pravilno.
Na vaš zaslon lahko vpliva eden ali več teh dejavnikov, ki vključujejo:
- Zatemnilnik na vašem radiu ni nastavljen ali je pokvarjen
- Prišlo je do težave s priključki vašega avtoradia
- Glavna glavna enota (stereo) je okvarjena
- Osvetlitev ozadja enote je okvarjena
- LCD zaslon je okvarjen
Upoštevajte, da je tudi pregorela varovalka del tega kontrolnega seznama, ki ga boste morali preučiti, ko boste ugotavljali napako avtomobilskega stereo zaslona.
5 načinov, kako popraviti avtoradio, ko zaslon ne deluje
Ko je vaš avtoradio nov in imate garancijo, je najpreprostejša rešitev, da ga odnesete k prodajalcu, kjer ga bodo popravili. Bolj zapletene situacije so, ko je vaš radio starejši s potečeno garancijo.
Upoštevajte, da so vsi avtomobili različni in vsi avtomobilski sistemi so različni, vključno z avtomobilskim avdio sistemom. Opisal sem osnovna načela in najpogostejše vzroke, ki so običajno krivci za rešitve teh težav.
Št. 1. Preverite nastavitev zatemnitve ali preverite žico osvetlitve.
Večina sodobnih avtomobilskih stereo naprav z digitalnim zaslonom ima funkcijo zatemnitve, ki bo povezana z radiem prek žice za osvetlitev.
Če vas zanima ožičenje avtoradio sistema, si oglejte moj drugi članek o tem Zakaj se moj avtoradio noče izklopiti.
Včasih je zaslon avtoradio presvetel in ko radio nima funkcije prikaza dan/noč, večina voznikov, vključno z mano, raje zmanjša svetlost zaslona (zlasti ponoči).
Rešitev za to je dvojna. Če je zatemnitev obrnjena, boste morali samo prilagoditi nastavitev in povečati svetlost. Običajno zatemnilnik deluje v tandemu z glasnostjo in tako jo boste spremenili.
Vendar bo najprej na voljo nastavitev, ki jo morate izbrati, da izberete način funkcije zatemnitve.
Če to ne deluje, je morda težava z žico za osvetlitev (lahko je poškodovan ali zrahljan) in če odstranite radio in preverite ožičenje, boste iskali oranžno ali oranžno/črno žico.
Razpravljanje o tem, kako ponovno napeljati avtoradio, je izven obsega tega članka, vendar si oglejte moj drugi članek Kako priključiti avtomobilske zvočnike na radio brez kabelskega snopa, kjer pregledam avtoradio in njegovo ožičenje.
Št. 2. Preverite konektorje avtoradia
Vaš avtoradio ni ena trdna enota. To pomeni, da je zaslon ločen od dejanske radijske enote, za njihovo povezavo pa se uporabljajo žice in konektorji.
Obstajata dva načina za povezavo zaslona z radijsko enoto:
- Spajkane priključne točke
- Mehanske priključne točke
Težavo lahko povzroči nekaj elementov, odvisno od vrste povezave, ki jo imate za vašo zaslonsko enoto.
Odstranjevanje zaslona iz avtoradio bi lahko predstavljalo težavo, če se ne smatrate za posameznika, ki si sam naredi sam. Postopek ni preveč zapleten in je dobro razložen v spodnjem kratkem videu.
V nekaterih primerih in odvisno od modela vašega avtoradia in zaslona, kot so nekateri modeli Sony, je odstranitev LCD zaslona zelo enostavna.
Če so mehanski konektorji (nekaj podobnega kabelskemu snopu), ki so zlomljeni ali kakor koli poškodovani, in menite, da bi to lahko bil vzrok težave, je mogoče te konektorje kupiti v servisni delavnici. V nasprotnem primeru ga boste morali prevzeti in jim pustiti, da vam nabavijo dele.
Če ima vaš zaslon spajkalne spoje , lahko vidite, da se je spajkalna točka ali žica zrahljala in vam je spet všeč malo narediti sam, nato pa morate vse, kar morate storiti, to, da jo pravilno spajkate.
Upoštevajte, da uporabljate različne vrste spajk za različne priključne točke in vezja.
#3. Preverite vse nastavitve uporabniškega načina in ponastavite radio
Če je vaš zaslon popolnoma izklopljen, tega popravka morda ne boste mogli poskusiti.
Če pa je zaslon zatemnjen in imate še vedno napajanje, morate najprej preveriti uporabniški priročnik in pregledati vse nastavitve in prednastavitve, ki jih ponuja vaš radio, da poskusite najti nastavitve svetlosti, ki bi jih lahko uporabili za prilagajanje vaš radio nazaj v normalno stanje.
#4. Preverite, ali je glavna enota, osvetlitev ozadja ali LCD okvarjena
Recimo, da ste že opravili vse korake in postopke, ki sem vam jih predstavil, kot so preverjanje zatemnitve, preverjanje žice za osvetlitev, preverjanje nastavitev in prednastavitev, poskus ponastavitve radia in preverjanje varovalk. V tem primeru lahko pride do težave z eno od treh stvari vašega avtoradia.
- Lahko je vaša glavna enota okvarjena
- Osvetlitev ozadja zaslona je okvarjena
- Sam LCD je pomanjkljiv.
V takšni situaciji je edina možnost, da ga odnesete na popravilo (če ga je mogoče popraviti). V nasprotnem primeru, če imate servisni načrt ali poprodajni radio z garancijo, bi ga morali zamenjati brez kakršnih koli težav.
Pred mnogimi leti sem šel skozi ta scenarij in na podlagi te izkušnje sem napisal članek o prenovljenih avtoradiih .
Št. 5. Preverite varovalko avtoradia
Glavni razlog, zakaj zaslon avtoradia morda ne deluje, je slaba varovalka. Tega sem se že na kratko dotaknil, ker je to najpogostejša težava avtoradio (radia).
Preverjanje varovalke je tudi najcenejši in najboljši način za popravilo vašega avtoradia, saj je varovalka namenjena zamenjavi.
Poleg tega so varovalke, ki se uporabljajo za vaš radio in drugo elektroniko v vašem avtomobilu, relativno poceni za zamenjavo. Resno, dobite lahko celo škatlo varovalk (to je več kot 250 varovalk) iz Amazona.
S tem kompletom vam nikoli več ne bo treba skrbeti, da bi v vašem avtomobilu pregorela še ena varovalka, verjetno do konca življenja, razen če imate težavo, ki se nadaljuje in kar naprej pregoreva.
Kje najdem varovalko za avtoradio?
Čeprav jo je enostavno zamenjati, boste morda imeli težave pri iskanju okvarjene varovalke.
Pri starejših avtomobilih bi bila varovalka nameščena na radiu, tako da bi morali odstraniti celoten stereo, da bi prišli do zadnjega dela, samo da bi zamenjali varovalko.
Včasih je to pomenilo, da je bilo treba sneti del ali večji del armaturne plošče. Če to velja za vaš model avtomobila in stereo naprave, je to lahko težava in ga boste morda morali odnesti v servisno delavnico.
Vendar, če nimate težav z umazanjem rok in ste navajeni malo narediti sam, bi moralo biti v redu. Edina stvar, ki jo boste potrebovali, je nekaj ur prostega časa.
Na srečo so pri večini sodobnih avtomobilov varovalke za avtoradie v škatli z varovalkami skupaj z vsemi drugimi varovalkami, ki so združene. To polje običajno najdete na armaturni plošči blizu volana ali pod pokrovom.
Kako vem, katero varovalko moram zamenjati?
Škatla z varovalkami bo imela pokrov, blagovna znamka na spodnji strani pa bo slika ali neka oblika vgravirane šablone, na tej sliki pa boste videli seznam varovalk, povezanih z določenimi imeni (to so njene kode).
Ta imena so nakazovala, katere varovalke so za katere avtomobilske dele in sisteme. Morali bi poiskati ime (kodo) varovalke, ki pravi Soba, Dodatki, Notranje luči ali Radio, in preveriti, ali je ta varovalka pregorela, nato pa jo zamenjati z novo, ki bi jo vaš avtoradio moral delovati in pravilno prikazovati.
Morda se sprašujete, zakaj se nekatera od teh kodnih imen ne nanašajo na radio. Včasih imajo proizvajalci kombinirana vezja v vašem vozilu in varovalka, ki se uporablja za vaš radio, bo uporabljena tudi za vaše notranje luči. Na splošno bi morali zamenjati vse varovalke, za katere boste ugotovili, da so pregorele.
Kako zamenjati varovalko avtoradia?
Če je kratek stik z maso vplival na tokokrog radia in povzročil val toka, je morda pregorela varovalka in vse, kar boste morali storiti, je, da sledite korakom, ki smo vam jih predstavili v zgornjem razdelku.
Vendar upoštevajte, da se morate prepričati, da je vsa tekočina, ki je bila razlita ali pomotoma prišla v ožičenje, očiščena in da so ožičenje ter priključne točke in konektorji suhi.
Kaj storiti, ko ima moj avtoradio napajanje, a ne zaslon?
V primeru, ko vaš radio še vedno deluje, vendar ni zaslona, je eden od scenarijev lahko ta, da je bila nastavitev ali zatemnitev do konca obrnjena. V tem primeru lahko poskusite ponastaviti avtoradio na tovarniške nastavitve.
This is slightly different from adjusting the dimmer and checking functions and settings on your car radio. Most radios, if not all due to their complicated nature, will have a reset button.
A reset button is usually found behind the removed faceplate of the radio. You will typically need something long and thin to get to the reset button, like a needle or a pen. Just remember that if you reset the radio, you will lose all saved data.
Why Is Car Touch Screen Not Working After Cleaning?
Water or moisture is the main problem that many people face after cleaning the radio screen.
The screen stops working when the liquid gets behind the LCD and short circuits the connection between the display and the radio unit.
If you cleaned your screen with water and it still works, you are in luck. And the only thing you would need to do is make sure the connection point and wires that sit between your display and the radio unit are dry.
The better way to clean the car radio screen and especially a touch screen is to use a soft microfiber cloth and clean off any dirt, dust, or fingerprints on the screen.
Using even a paper towel will cause scratches on the touchscreen, so do not do that.
Why Is My Car Radio Touch Screen Not Responding?
The touchscreen is only fun when it’s fully responsive. Otherwise, your car radio does not function.
It often happens that touchscreens in car radios lose responsiveness, and there are two main reasons why this happens:
- Dirt or dust on the screen blocks its direct contact with your fingers, causing the touchscreen to be unresponsive. To avoid this, clean the screen regularly with a microfiber cloth and do not touch the screen with dirty hands.
- Another reason for the screen not to respond is when it loses its calibration. For example, you have to re-calibrate your touch screen if you notice it does not respond to your fingers or register the touch when your finger is in an “offset” to the icon you need to touch.
Why Is My Car Radio Display Fading?
When the LCD car screen is fading, there is a problem with either connection of the flat wire or with the liquid screen itself.
It is a common problem, especially in the one-din head units, but the fix is easy but not always possible at home.
Car radio screens start to fade over time because the internal connections become loose or when the screen is mechanically damaged, for example, when it is pressed using too much finger pressure.
Repair of the fading damaged screen is not always possible. To find the reason, you have to remove the screen, clean all flat wire connections, and solder it back to its original position.
If that does not help, it means you have to replace a screen with the new one.
Screen replacement in car radios is not the easiest task. If you are not a DYI or do not have much experience with electronic repairs, it is better to give the radio to a professional.
Is it worth repairing the display? It depends on the radio type, and if this is an expensive model, then definitely yes. On the other hand, if your radio is not too costly or not the new one, it is better and cheaper to replace it with the new one.
Why Is the Android Radio Touch Screen Not Working?
When your android touch screen has stopped working, in most cases, it means that it has frozen. So you can touch it at any point, and it will not respond.
The solution for this is relatively easy.
- First, you have to put all your fingers on the screen and hold it for a couple of seconds.
- Then, the screen will come to the re-calibration mode, and it will reset.
- When it does, you will see on the screen the information, press the “Okay” button, and it will be back to normal.
Why Car Radio Screen Went Black?
Screens in the car radios can randomly go black after connecting additional equipment like the backup camera or reinstalling the software.
If the screen is not mechanically damaged and is working fine but suddenly lost its screen, the simplest way to fix it is to press the reset button and hold it depending on the radio for between 5 and 10 seconds.
After that, most screens come back to normal functioning.
If the display panel on the car stereo receiver is dim or does not light, the connectors may need to be cleaned, or a mode setting needs to be adjusted.
Another problem can occur when the radio works, but it has internal screen damage. To fix this, you have to either disassemble the radio, remove the screen, measure the electrical resistance on all connections, or give the radio to a professional.
Why Is My Radio Screen Dim?
The dimmer setting allows dimming the display and buttons at night, so it does not have to be as bright as during the day.
The car radio dimmer can be set manually, synchronized to the clock, or activated with your car lights, and most dimmed screen problems are related to the last option when the radio has to be connected to the car lights.
If the display is too dim with the brightness set to the highest level, the dimmer could be activated. Your radio may be equipped with a separate brightness setting for when the dimmer mode is activated.
This can also happen if the car sends an incorrect signal to the radio indicating that the car lights are on and the display should be dimmed.
To solve this problem, you should manually switch the dimmer off or set the dimmed brightness to the maximum level.
If, after changing the settings on your radio, the display is still too dim or too bright, the radio may be faulty, and you may need to contact the repair service of the radio manufacturer.
Zaključek
It’s all good and well that nowadays you can purchase the most fantastic car radio with a superb display that can achieve incredible things.
However, compared to older, more robust car stereos, the risk of something getting damaged or not working correctly is a real issue and one you will have to face if you are not willing to take it to an automotive repair shop.
Furthermore, there are quite a few factors that could be at the root of this problem. However, most of them are not severe, and they can be rectified without the need to take your car in so your radio can be repaired.
I have covered these issues, and they include a faulty illumination wire, an incorrect dimming mode or setting, and a bad fuse.
The last thing to note is that if you have gone through all the steps I have provided, and your car stereo display is still not working, you will most likely have to take it to a professional service to figure out what the problem is.
Pogosta vprašanja
How to Reset Car Touch Screen?
Resetting a touch screen requires turning the radio off and turn on again after around 3 seconds. This should bring the screen to its default settings.
Some car radios have a hard reset button that you must press and hold for around 10 seconds. This will usually be located in the menu or settings of the radio.
If you can’t find the reset button, you can also try disconnecting the battery for a few minutes and reconnecting. This is called a hard reset.
After resetting the touch screen, you may need to calibrate it. You can usually do this by going into the menu or settings of the radio and finding the calibration option.
Calibrating a touch screen is important because it helps the radio accurately register your touches.
If you don’t calibrate the screen, you might find that it’s unresponsive or that your touches are inaccurate.
Why My Touch Screen Radio Has White Screen?
Instead of seeing the main menu or the images on the screen when they switch on the radio, you can see a white screen.
Don’t be scared because this doesn’t necessarily mean the stereo is damaged; in most cases, you can fix this in a few simple steps.
1. Reset the radio.
If you see a white screen the first time you turn the stereo on, switch it off and see if its peripheral power supply voltage is nominal, then switch it on again.
2. Ensure the radio is connected correctly.
If the car stereo with GPS still shows a white screen after switching it on for the second or third time, you may need to check if the peripheral receptacle is placed correctly.
Also, ensure that the plugs have been tightly inserted into the sockets.
3. Reinstall the stereo.
If the problem continues, remove the DVD player from your dashboard and reinstall it again.
Re-plug the cables and ensure they are correctly connected, especially the wires between the front panel and the central unit.
If none of the above solves the problem and your radio still have a white screen, it is advisable to take it to the nearest service centre for diagnosis.
It is also possible that the problem lies in the LCD panel and would require a replacement.
Why Is My Car Screen Flickering?

#5. If the touch screen is still unresponsive, take the radio to a professional for further diagnosis.
Why does the Android Head Unit Has Power but No Display?
When the Android car stereo is functional, but the screen does not work, it means your screen’s backlight is not powered.
This can be caused by several things:
1. A blown fuse
2. A faulty wire connection
3. A problem with the LCD itself.
The first thing you should do is check all the fuses in your car and replace any that are blown. If fuses are okay, there may be a problem with the circuits’ screen panel or solder connections.
In that case, you will need to take your car to a mechanic or electronic specialist to have it checked out.
Why Is Pioneer Radio Touch Screen Not Working?
Screens in Pioneer car stereos often stop working due to a blown fuse or loose wires.
