20 Most Recent Sony Bravia KDL-42V4100 42 in. LCD TV - Page 3 Questions & Answers


Hi there

this is not meant as a solution, but a tip if you`d like to get an answer.
You should clarify in which occasion you get either sound and no video or black screen with sound.
This is a little confusing for a repairman.

Is the TV turns on and off cycles all the time? Sounds like something wrong with the main board.

After checking DVD and other accesaries (functioning OK), I turned the power off for the Cable Box and restart to reset the Cable Box which resored the VIDEO function. I recommend the same procedure for those who has a Cable Box.

Hi,

Sounds like there is a short on the power board or the power board has gone faulty.

Look on the power board to see if any of the capacitors are bulged or if there are any other components burnt out. The TV is going into protect mode because of an over current, which points to a short on the board or a component has gone short circuit.
Thanks

I know this is old bu does it still do this?

Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.
Replacement boards can be found at a good price at Shopjimmy.com

Hi,

There are a number reasons why this might happen:
  • The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
  • The panel has died - Need a new panel
  • A cable has worked itself loose or is broken
  • The inverter has gone - Need new inverter
  • The driver board is faulty
Thanks

This usually means the lamp or the ballast that powers the lamp is bad.

Could be anything! From a main board to a power supply. I recommend getting service on it from a authorized sony service center. If standby light doesn't appear at all for any given time, then it maybe the power supply.

Sony Bravia... | Answered on Jun 23, 2009


If the Standby light is blinking at the front panel of the TV, it seems that there is an internal malfunction occurred in the TV.
I will forward a link to a page where you can get more information and troubleshooting steps for this issue.

http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=C399467

Please perform the steps provided on the page. If the issue still persists then service of the TV is required.

I have a Sony Bravia KDL 40S 2000 (lcd tv - mfg 06') The power goes into standby which I know could be several things but my question is this....I'm into the set only $100 so far. Is there some pointers you can tell me to look for with the once I remove the case for a visual look see? I don't want to invest another $100 to find out it's a $400 fix....any info would be great b4 I chuck it. (FYI-I am mech. inclined so I wont use info like an idiot.) Thx - Dan Rathburn

edit your inputs and make sure itv1 has't been put on skip


your channel 4 could have been automatically deleted if you did an auto program on the channels.
Poke around in the menu and you should be able to tell it to display channel 4

Hi Sherry, you can test your remote control to see if all the keys work correctly
Take your cell phone, put in camera mode and point the emitting LED of the remote control towards the camera,
press the keys, one at a time and see if the emitting LED is illuminated, if so, try the volume up key, if the light does not turn on, you could carefully disassemble the remote control and clean the contacts and the keyboard internally rubber,
Do not use alcohol to clean
the rubber keyboard, you can clean it with warm water and detergent then let it dry very well,
the contact plate, you can use a cloth with some liquid to clean the glass,
the idea is to remove the rubber residue on the contacts
then arm again and test, but you have results consult a specialized technical service
I hope you find the suggestion useful
Greetings Franco Dosil

Hola Sherry, puedes probar tu control remoto para saber si todas la teclas funcionan correctamente
Toma tu celular, pon en modo camara y apunta el Led emisor del control remoto hacia la camara,
presiona las teclas, una por vez y fijate si se ilumina el Led emisor, si es asi, prueba la tecla de subir el volumen, si no se prende la luz, podrias desarmar con cuidado el control remoto y limpiar internamente los contacto y el teclado de goma,
No Uses Alcohol para limpiar
el teclado de goma, lo puedes limpiar con agua tibia y detergente luego dejalo secar muy bien,
la placa de los contactos, puedes usar un pa?o con un poco de liquido para limpiar los vidrios,
la idea es sacar el residuo de goma que hay sobre los contactos
luego arma nuevamente y prueba, sino tienes resultados consulta a un servicio tecnico especializado
Espero te resulte util la sugerencia
Saludos Franco Dosil
