    Thanks so much. I am hopeful this is what I need. We were trying to just sell the TV since looking at it wasn't bringing any answers. With this, though, I may be able to repair an otherwise great TV. We shall see once I get the part in-hand. Glad the main board isn't one of the harder to get to boards, too. Thanks for the help and I will keep you posted on how the repair goes!

    That should sove the issue for you. the only other board with even a long shot of causing it would be the Tcon, But the Tcon would also make lines appear in most cases, but usually if its just color issues or a snowy pic its almost always a main board.

    I cannot bump the contrast more than one place in either direction. Same with the brightness. No lines, though. If I can get the picture fixed I will buy replacement speakers and be in great shape!

SOURCE: unlock Olevia remote control

Why are the menu settings that I changed not being saved? A. The TV is in Showroom mode. The following steps will help you switch to Home mode.

  1. Press Menu button from the remote,
  2. Press Down arrow key until you see the word Picture, then press the Right arrow key,
  3. Press Down arrow key until you see Mode, then press the Right arrow key,
  4. Press Down arrow key until you see Power Up, then press the Right arrow key,
  5. Press Down arrow key until you see Home, then press the Enter key,
  6. Press Menu button four times to exit out from the OSD Menu.
***Showroom mode is designed for retailers to display the TV and to protect from shoppers changing the settings that are predetermined for shelf display environment.***

The TV will not let you set brightness, contrast, color or tint in the preset modes like Vivid, Movie, Standard etc. Look for a mode that says custom, user etc..

Cannot Control Picture Settings?

First thing I would do is unplug the set for about 20 seconds then if you still had the problem, have it fixed by an authorized repair shop for that brand as it should still be in warranty.
