Comment: I have a Sony Bravia KDL-46S4100. When I turn it on, the SOUND is on, NO PICTURE. If I leave the TV on for about 15 to 20 minutes, turn it off and then turn on again. Now both Sound and Picuture came on. I don't know whether it is a power supply problem or the backlight inverter problem. Please tell me what wrong with it, so that I can order the right part to fix this problem. Thanks in advance.

SOURCE: I have a Flat screen

Are the lines all the way across the screen? or just a few? Solid black - or trannslucent?

Like this??


Horizontal drive has either data, voltage, or control problem from the pixel registry circuit......get it serviced before the problem spreads causing further damage.

However, in all likelyhood, the panel itself is bad. The Bravia line has had a bad rap about the faulty displays, and at $1800 replacement (plus labor) - it may be time to call SONY direct to complain!

Thanks!!

it sounds like your back light might be going out. You might be able to fix this by installing a new backlight inverter board.

I have a sony bravia kdl 40v 5100 for less than two years and i did not purchased an extended warranty and now my tv is down.
I have no picture, no sound just a black screen when i turn the power on, the power (green) light is lite up and the tv turns off by itself for like less than 30 seconds. I have tried to press as many buttons on the remote control and on the side of the TV to get any message but nothing seem to happen. Any suggestions and solutions? Thanks
