Sharp 60" LCD TV Aquos LC-60LE650U image issues

[Abe700]

Hi,
I have a Sharp 60" TV Model LC-60LE650U LCD TV. The picture is darker, distorted and keeps getting horizontal dark flashing lines or bands.


The things I have done:

1. Tap and twist the edges screen, nothing happens and picture remained the same.
2. Ordered new T-con card, problem remains.
3. I thought of taking one ribbon out of the t-Con and turn the unit on, then half of the screen went white and the other half remained having the same problem.
4. I put the one I disconnected back, and disconnected the other one ... then half of the screen went white, and the other have was perfectly fine nice picture.
5. hm, that got me thinking may be the ribbon is the problem, so I switch ribbons, but that did not have any effect on the previous results. Ribbons acted the same when switched.

Any idea what could be the problem? Since one half of the screen works perfectly when the defected half is disconnected, why when we connect both the whole screen goes bad?

Thanks!

Well sadly that is a sign of panel failure. Maybe at the very least you could try pressing on the tab bonds to see if the picture comes back.

I'm surprised I don't see too many sharp panels fail. Mainly AUO and Samsung.

Thank you freakaftr8 for your replay,
If you look at the last picture, it shows half the panel working fine when the other half is unplugged. That made me rule out the panel failure. Pressing on the tab bonds does not make any difference.

Yes but if there us a short in the panel on the bad side this will take down the drive voltages and functions that the tcon uses to drive the panel causing both sides to display the problem. Kind if like mirroring the image.

Can't be some shorted capacitor on the panel's PCB?

freakaftr8 seemed to be confident that the panel was the problem. So I did not want to waste much more time on it. Decided to part it.

May be a candidate for surgery, check the threads.

You could remove the tabs on either the left or right side of the panel. You need to figure out wich side of the panel is bad and remove those tabs on the side ( 3 or 4 small tabs ).

i think something can be made, if you want i had a similar issue and solved in a difficult manner, search for Sony kdl-60ex700 for info. Not sure if same problem, surely similar but different screen model.

that was likely a mistake.... but it depends on what you wanted to do with the set. This is a old thread... since then people have found easy ways to save the set. Just swapping tcon to panel cables isn't doing nothing other than checking which side of the set gives the "best" picture.... from there you need to remove the tabs of the offending side.
Anyways, the boards are probably OK.
