Re: Sharp LC-70LE55OU No video

Have swapped out the ribbon cables, they appear fine though. No signs of corrosion or anything. It takes a bit of finesse to get them on and off the bottom of the tv.

Was fiddling around trying to update the firmware but I can only see half the tv screen and can't read the steps.

The replacement ebay tcon board came with 2 ribbons attached, tried both boards with both sets of ribbons, same problem either setup.

Is there any repairs that can be done on the panel? Ole google is failing me on that one.

Ended up setting up a mirror on the other side of the tv so I could see heh

Short of straight disconnecting the ribbons I saw no difference tapping or wiggling them...

With them both plugged in you initially get picture but it quickly fades away, its only with one of them removed there is a difference.

If your facing the back of the TV and disconnect the right ribbon cable then walk around to the front of the TV the left side of the screen is white, but the right side has picture and it stays on.

So my 70 inch sharp TV decided it doesn't feel like displaying any picture anymore

If left off for a while, when you very first turn it on, you get picture for a few seconds then it freezes and kind of fades away, but the backlight stays on. You can turn the tv on and off again but you just get a backlit screen. The white led in the bottom front stays lit up white and doesn't flash at all that I can notice for codes.

Tried factory reset, leaving it sit unplugged a few days, same issue.
Bought a new power supply hoping that was the culprit but same issue....
