I got a Sony Bravia KDL-40WL135. Blank screen. There's two LED lights: red standby and green power light.

I think that's a SONY error code, I tried to look it up but can't find anything useful. I have replaced the power supply, AU board, backlight inverter, logical board, and the second power supply board. Any suggestions? I haven't checked the t-con bo

Hi, can you help me with this TV please. Hi, I have a Olevia 232-T11 LCD TV. First my TV wouldn't turn and the blue light just stayed on.

I have a Vizio VW32LHDTV10A that produces sound but no picture. I have checked the main power board for 24v to both backlight inverters and 24v is present. I then hooked up both backlight inverters and turned the TV on and the blue LED on the Slave inverter comes on, but goes off after only a few seconds. What further tests could I perform to check which part is defective or what component is the most likely cause?
