You're welcome and I wish there was a quick fix. When the problem persists on all devices and is also present over the MENU, you are looking at a fault in the DMD board which processes all of the video before sending it to the screen. If MENU was not affected, then you'd be instead looking at a Mainboard. Average cost for this type of repair is around $150 for the board, and then another $200 for labor.
