Hi lads, TV working fine except that what it has a dark area on the right lower side. Also, the previous picture stays on the screen. When Tcon flex cable disconnected from the screen, a screen is clear white. All Voltages and capacitors checked and look OK. Looking advise from colleagues with experience, could there be faulty TCON.
