So this TCL 55S401 I got today has backlights, no image on screen but responds with audible clicks when I press the buttons. I tried another t-con but no change in status.
When I detach the FFCs one at a time from the T-CON to the Source Driver Boards I expect that side of the screen would be white, but when I do this both sides remain black (or blue with the backlights) with either FFC detached.
The t-con has 12v going to it and the processor is very warm to the touch in short order, but the processor on the Main Board seems cool/ambient temperature.
I've never seen a full black screen when the FFC's are detached individually. Does this suggest the main board has a problem, or does anyone think the screen is likely the culprit?
This TV is hardly worth putting much time and money in so I'm hoping for the short answer...if anyone has any ideas?
Thanks everyone!
