Hello and sorry you're having problems. In order to help, I need to ask for some more info here:

1) Does the set still have sound?

2) If you grab the original remote and press MENU, does the MENU display clearly and normally?

3) If you shine a flashlight against the screen at a 45 degree angle and look closely, can you see shadows of the programming behind the screen?

1. yes it has sound
2. you cant see the menu
3. yes

Thank you for the reply. This indicates a failure with the set's backlighting, which is powered by the power supply board internally. I realize this is bad news but generally this require replacement of the power supply/backlight board to fix it (as there are no settings that will shut the backlight off).

However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.

The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.

If that does not work, then please double check that model number off of the back of the TV (since it's one or two digits off and therefore not showing up in any searches).

Are you still with me here?

Expert:  Aric replied 3 months ago.

I'm unsure why you're unable to reply, but it's been 10 minutes since I posted those steps. If the screen is still not backlit then the power supply/LED driver board needs to be replaced, which is on average a $225 repair on this set. In this case, if you'd like, you can use the link below to locate a shop in your area:

Alternatively, if this is something that you're looking to try to repair yourself, then i would need you to double check that model number off of the back of the set, postback here with it, and then I can search for the board for your TV.

Other than that, I'm sorry for the bad news here and wish there were a quick fix.
