Hello, my Gateway XHD3000 is experiencing random blackouts. The panel just goes out, dark, nothing, black with back light on. Even the onscreen display menu is not visible. This has begun happening randomly throughout the day, becoming more and more frequent. The only thing I've been able to do to remedy the the problem is to power the panel, wait 30-45 minutes and turn it back on.

Take a really bright flashlight and shine it at the display when it goes out, if you can see a picture you have an issue in the backlight circuit causing it to go into shutdown mode. If not, you have a problem with the data/display board.
