Sharp AQUOS LED TV diplays green hue/tint

Hello all,

I was wondering if anyone could possibly provide some advice on a display issue i am having. The TV is a Sharp LC-70LE650U that is about three years old. When TV is turned on a green hue/tint appears in the center of the screen, if slight pressure is applied to the upper corner of the TV the green hue/tint goes away. The hue/tint is there regardless of video input is in use.

Thank you for any advice that could be provided!

Seems like the tv frame is bent, or sagging? Is the TV wall mounted?
If somebody knocked the TV, then one of the screw(s) holding the bezel to the frame may have broken the plastic nut they're screwed into? Or, it may have been loose to begin with.

Short term, I'd grab an adjustable padded woodworking clamp from a big box store, and see if a little pressure on the corner solves the green screen.

Then, I'd carefully check to make sure all the rear bezel screws were tight.

Probably not a fix, but have you tried unplugging and re-plugging power cord? I've had our Sharp do some weird color things once or twice and that was the fix on ours, although the symptoms were not exactly like yours.

It definitely looks like a panel issue.

Try changing the aspect ratio.
If the green bar stays the same.... you may be looking at a panel replacement.

Hello Hal_S,

The tv is not wall mountedand i will verify all is present and tight. I think i described my screen issue incorrectly. When pressure is applied to back of the tv upper right corner the green screen goes away.

And that sounds like the TV frame is bent or sagging.
If physically pushing on the exterior of the TV cures the problem,
then it's not electronic,
it's LED so it's not magnetic (old CRT's developed something similar if you placed metal (i.e. VCR or cable box) close to the screen)
and that leaves warping of the screen because the frame is sagging or bent.

What would you recommend? The TV sat on a stand, it has never been wall mounted. Do you think the TV is a loss?

Thank you for the information

I would try to work with several woodworking clamps, some duct tape, and some thin bars of wood that could be put behind the TV to create an inverse warp to make the green tint go away.
