Hello and sorry you're having problems.

1) How long have you owned the set3 for and when did the problem occur?
2) What is connected to the TV for sources (cable box, DVD player, etc.), and does this issue occur regardless of which source you're viewing from?
3) If you press MENU using the original TV remote, or the MENU button on the TV itself- does the MENU display normally or also dark?

Hi , I`m Jack , different tech. here
Perhaps I can help you with this problem.

Let me know if you still need help with this ?

Expert:  Jack replied 7 months ago.

If you ever come around to see this , here is something that may help ;

You will need to enter the setup menu for this with the master remote if you haven`t done that already ;

Open the menu and go to CONFIGURATION , open that and go to AMBILIGHT and open it.
You will see different items in there to setup the ambilight effect so i will explain what this ambilight does ;
Mainly it will adjust the brightness and have some effect on the colors depending on the room lighting so it works directly on the brightness of the screen , turning it down (the brightness) at low light level (night) and up when the sun is in the room for example.
This means that even if you turn up the brightness all the way up like you did ,it will have little effect as this ambilight takes control of it.
So in that ambilight menu you may try first to turn it off completely and see what that does or you can set its MODE to MODERATE for example.
Try it either ways and note that once you turn it off you may have to re-adjust the brightness level, it may be too high now.
Another item that could be in play here but that is not on all models is the VIDEO ADJUSTMENTS , if yours has it then take a look in there , there may presets video modes like CINEMA,GAMES,SPORTS ,VIVID etc. if so then try those as well.
