Re: Sharp LC-70LE757U TV not working (2-5 signal)

So I've taken off the bezel of the TV and I can access the bad side panel for the display that was NOT working when tested. There are five ribbon cables (not detachable) that go from the edge panels to the LCD display. I have pictures of what I have so far. You're saying that if I detach these five cables from the LCD then the screen should "work" again? If so how do I detach them correctly, I've been looking for hours and I can't find a solution....

If I remove the bad side will the picture quality improve or will it stay the same as it is in the pictures I sent?

Absolutely nothing, not even a backlight.

So what is my solution?

Re: Sharp LC-70LE757U TV not working (2-5 signal)

If the left ribbon is plugged into the left side-edge pannel (but not the right one) there is full display but the colors are not correct.

Sorry if I misunderstood, still getting used to TV and electronic jargon...

You said to disconnect the ribbon cables in the corners of the panel which I did. There is a small ribbon connector in the bottom left corner and one in the bottom right corner of the panel that I disconnected from the side edge boards on either side. When I disconnected both of those ribbon cables but kept the four ribbon cables connecting to the T-Com to the bottom edge plugged in this is what happened to the screen. I had backlight unlike when the two smaller ribbon cables are connected but anything that the screen displays shows...

With all four main ribbons plugged in and the ribbons in the bottom left and right corners the screen had backlight and only displayed color when it started up and when I pressed the menu button (as seen in picture)...

I've been looking around these fora since I have an LC-70LE757U Sharp flatscreen TV and it has the same problem as many other cases but not exactly the same. When you plug it in, the Sharp symbol on the bottom flashes the 2 long and 5 short signals that something is wrong with the T-Com board. I found this attached support letter which helped somewhat. The T-Com has four ribbons attached to it and, with all of them unplugged, the backlight comes on. With one plugged in, there are some lines down the display on the left. With two plugged in just backlight. With three plugged in, the two inner ribbons...
