20 Most Recent Sony BRAVIA KDL-52V4100 52" LCD TV Questions & Answers


Nice TV ,but, is an LCD . most likely cause may be after long service life the 'Cold Cathode' tubes have begun to grow a carbon track down from the high voltage input . This causes the power supply for that voltage to determine too much load and shuts down . I am surprised you do not see a flashing LED pattern but this does not mean that the condition was communicated to the ECU .
That is a lot of tubes to change at about 40 usd for 10 pieces . It is also a Pain in your seat cushions to disassemble to confirm (ie: delicate connections to undo , mechanical puzzles to solve) I have seen Youtube videos of people converting to LED backlights with very nice results . It is possible but not recommended to change just the bad ones , you will soon have to do the rest anyway .
There may be a shop that does it often and could save $ compared to replacing with LED tv set that size or maybe a shop that converts(not me!)
Luck ... Hugh

SOUNDS LIKE EITHER THE INVENTER BOARD IS PLAYING UP OR THE POWER SUPPLYBOARD,LOOK FOR FAULTY CAPACITORS.ITS THE BACKLIGHT THAT LETS YOU SEE WHAT IS BEING SHOWN ON THE LCD SCREEN BY LIGHTING IT UP,IF YOU LOOKED CAREFULLY OR SHOWN A TORCH ON IT YOU WOULD SEE THE SCREEN.SOMETIMES IF YOU MANAGE TO TURN THE BACKLIGHT DOWN A BIT BY TURNING DOWN THE BRIGHTNESS ON TV,THE BACKLIGHT WILL COME ON AGAIN,IT IS CUTTING OUT DUE TO LACK OF POWER OR FAULTY CAPACITORS ON THE PSB.DO SOME GOOGLE SEARCHING,GOOD LUCK

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

Aron,

To perform a reset you will need to disconnect the TV completely from power for at least 30 seconds, if this doesn't resolve your problem then you may have hardware that has expired in your device. Without physically looking at your device I can't say with certainty what your problem is, it could be your PCB. There are video's online you can visit on how to test a PCB for faults.
If you are not comfortable troubleshooting your device I would suggest contacting a local electronic repair shop near you, however I will link you to a generic instructional video showing you how to perform basic troubleshooting of your device.

Hope this helps,
Best regards

Although I am just guessing, most Sony equipment uses metric screws. Go to a Home Depot or similar store and take the piece that you have that contains the threaded fittings and they will help you find the screws you need. https://www.manualslib.com/manual/793567/Sony-Kdl-32xbr6.html?page=7#manual This page of the manual gives some info about the screws such as not longer than 1/2" (or 12mm) to prevent damage to the set. Sony customer service may be able to supply replacement screws too.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.
