Hello there!
Have this Philips with no image at all. When I plug it to the outlet, it turns on without pressing the power button, and after a moment, it turns off, then starts again. I checked the 12v and 3.3v voltages on the main board connector that goes to the T-con, but it only has the former (12v). Any clues, guys?... -
