no picture but have sound mod number le37a557p2f. tv 6years old never had a problem one month ago got tv/broadband package with EE worked fine for one week any ideas
Hello, I need bit more info about TV to troubleshoot the problem.Does TV menu screen come up when push menu button on TV or its remote?Does TV screen glow/ shows any light when power up TV?What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?These info will help to troubleshoot the problem.Thanks.

i only get sound. nothing else i do have a dvd player pluged in one port and the EE system in the second port

OK, so nothing appears on screen, no backlight and graphics etc, is this correct?If so, please shine a good flash light on TV screen bit closely with some degree to observe any faint image inside screen, is there any faint image visible inside screen?

ok tried that can not see anything in your opinion could the EE system have caused this problem

No, TV itself has got internal failure due to age factor and apperantely not caused by EE system, most probably the backlight inverter section on power supply board has failed thus causing black screen, LCD panel needs backlight to present its image and when backlight system fails for some reason the screen will turn to black/dark and nothing is visible.Please check following link to view sample/ used power supply board image and price info and TV tech will swap the power supply board in TV.. times main board of TV also can cause this problem because it controls the backlight function in TV. I trust my input will help you out.
