If the green light stay's on but no picture, meaning black screen! Then you have a bad back light inverter. You can order this at www.shopjimmy.com, select sony then your model number.

If you are somewhat handy you could do it yourself! but it requirestaken tv fully apart. There are a lot of screws that should be baggedseparate as you go along. To ensure tv can be reassembled. follow thesesteps or have a expert do it!

1) remove shell (casing)
2) remove second layer, this will have your signal boards on it (a/v etc...)
3the back light inverter has a metal cover over it, with very tinyscrews. Also you will see multiple wire plugs going into it. Usuallywhite/pink or white/blue.

If this sounds to confusing Irecommend having an expert do this work! If you have found this helpful. Good luck!!

Part is $89.95

There is a big block in my TV screen covering 8 to 10 inches. I have a Sony Bravia, model KDL-40S4100, and i bought it in 2008.


if it is a black block, look in the menu under closed captions and see if it is in the text mode. if so change back to cc1 or turn off.

SONY BRAVIA KDL-40s4100 is not working right


Please check whether the connections are secured between the TV and the connected devices.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Try connecting the TV to a different wall outlet and check if that helps.

Please connect a different device to the TV and check whether the issue persists.

If the issue still persists service of the TV is determined.

No Picture on TV when Power is on


This seet should provide some diagnostic help. The standby light should be blinking a repeated count with a pause. Post that count here. Also, is there sound?

The above info will indicate the problem circuit which will then suggest the remedy.

Thanks,
Dan
