Working on this unit, I have check voltage to main board and are getting the 13 & 3 and 5 volts. I have check voltage to t con board and get 12v on first 2 and zero on last 2 pins. The unit does power on and has backlight but no Video or sound. I was just getting backlight but I have messed with ribbon cables on t con board and now I get some red lines on left side of screen.
