I have a KDL-32BX330 that just went dead. It turns on, I can see the backlights light up and a very faded/yellowish bleeded looking Sony logo and then after about 5-10 seconds the TV turns off. As of now I know its not the Main board as it does the same thing when the board is removed, and I also tested a replacement main board to be sure.

As far as I can tell there is just the main, power and inverter. -

Re: Sony Bravia KDL-32BX330 Backlights but No Picture
I have one in shop. The P.S. voltages are fine. The original main board power came on, backlight came on but has no sound, picture or menu. Ordered a main board the set never turned on, no backlight, nothing. We returned that board and got another. The set turned on, had backlight but no menu, picture or sound . Same as the original board.
I checked the bower supply voltages and they were good. All cable are connected and main board chips never got really hot. all bad main boards?Comment

Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -

I was watching youtube yesterday, when I paused it to go to the washroom. When I came back, the right side of the screen was showing half of the youtube channel and the left was black. I powered off/on the unit with the remote and now I have no picture whatsoever except for the bluish backlight. I did the factory reset (power + vol down), and now I when I power on I get the startup music, backlight but no picture.
I took the back cover off, and reseated all cables but unfortunately same issue. I took some voltage measurements on the main 2 headers from the power supply board and... -
Hi Folks,
I have a 65" newer (2021 model) that has no sign of life. No backlight, no front LED (assuming it has one) and no audio or turn on chime.
Photos below of the system
The CN6401 Connector has the following vitals:
STBY_3.3V is 3.432 V
BL_ON low (0.153 V)
BL_ERR low (0.051V)
POWER_ON 3.42 V (as soon as I plug it into the wall this comes on)
REG12V pins 12.7 V
TCON_VCC12V pins low (0.11V)
TCON_ON low (0.155)
Large caps are at 392V as soon as I plug into power
Seems like a Mainboard... -
Hello! I would like to repair my father's Sony Bravia KDL-40v4100 LCD TV. It was in perfect working order the last time I used it before the pandemic. Then it sat plugged in but unused for a year or more. And now everything still works except that there is no picture on the screen. A relay can be heard to click when the power cable is connected. When the power button is pressed there is a green power LED and then the backlight turns on. If I connect an HDMI cable and play something with audio I can hear it through the speakers. The remote control buttons are recognized. There is just never anything...
