Hi guys,
Front LED turns from red to blue, then blinks 6x red then stays blue, mainboard doesn't turn on the backlight and TV becomes unresponsive after power on. When I force the backlight on I see only a few square inch large noisy picture without any content.
All voltages on the board are present, 12V, 3V3, 5V, 2.6V, 1V. Crystal for uC oscillates at correct frequency 27MHz but forcing it to stop doesn't do anything. It looks like the uC FW doesn't run...
schematic is attached
Any ideas?
