Your LCD backlighting system is not functioning.Your LCD main board should detect the problem and would give you and error code.This needs an immediate service.See if the Tv is under warranty then you can return it an get a replacement.It usually the inverter that has the problem but also either one(even just one)baclighting bulb goes off it will shut off all the backlighting bulbs,thus a sound with no picture as a result.

    Hi edmisch
    I'm happy to have found your reply because I have a similar but slightly different problem. Since a few days ago, when I turn my 42LG30 TV on, I see the input source in the upper right corner (fx. HDMI 1) and after 2 seconds the picture just fades out to a black screen. Sound can be heard though. After reading your answer here, I would guess that the problem in my TV lies with the inverter and not in the bacllight since the screen shows for 2 seconds every time I turn it on. This happand of-course 1 month after the warrenty expired - damn. Is there a chance that I am right?

I am getting black borders top & bottom on some channels and side to side as well on Fox on my Dish Net receiver 322 to analog TV.


Hey there! Becki Barned from Dish Network customer service here. The black borders are usually caused by watching standard definition programming on a high definition television. Try to change the format on your tv. Either by pressing the * button below the 7, or trying a format or display button on the original tv remote. Hope this helps!!!

If you have a dish network system as listed in post a DVR 625 this is NOT possible, it will only work with VIP series Dish Network recivers. and they must be used on teh same model reciever such as Vip 722, tranfer to EXT HD then Watch on another 722!

No pic but sound :/


You are having a high voltage problem. Quite possibly in the horizontal deflection. I would check the horizontal output and regulator transistors.
