Backlight works on this TV but no video or OSD showing. I started poking around the TCON board and found one of the large ASICs was cold to the touch so I started checking voltages. Found a regulator getting 0.75V in and nothing out, and eventually traced the voltage rail back to one of the two ribbon cables going to the LCD panel.
Unplugging this cable brings the picture back to the other half of the panel, so am I correct in thinking the panel is toast? The ribbon cables go to those small PCBs that run along the width of the panel and have some surface mount components on them. Is there a possibility there could be a fault with this and not the panel?
