Sharp Aquos LC-52D62U Snowy & shifted picture

[jason123]

Hi folks,
Picked this up at a garage sale and though several posts show "Snowy" staticy picture, this one is a bit different in that the menu boxes are also duplicated / shifted. I'm assuming it's a TCON (this model has a separate TCON board) but I'm not sure I want to spend the money trying things out. Anyone had seen this before?
Thank you

Looks like a bad panel issue. Can you open the TV and post clear focused pictures of the T-CON Bd? There might be a means to save it yet.

Main board problem. That issue is very common with the D62u and D64u series. The weird static type artifacts are a dead giveaway. I've had plenty with just the artifacts and others that show double / triple or more images in addition to the artifacts.

Thank you.. is the main board repairable (Is it a BGA reflow / bake issue)?

Ok, try not to laugh too hard, but the fix was to clean the dust off the main board! it's working like a champ now.
Thanks

Unless the dust is conductive, i'd be weary that it does it again. Beware!

Agreed. Moving it around and touching the components on it probably temporarily improved a bad connection on a BGA chip. I would guess the problem will return eventually. Regardless, that proves its the main board.

I think the problem will return.

It seems to me it was only a common bad connection on the lvds cable, the dust doesn't mean anything..

Ok, you're all right! the problem came back almost 2 weeks after I thought it was simply dirt. To repair, I've ordered the cheap option a Tcon - didn't fix it.
I then ordered a main board. Didn't fix it. Defective board? maybe
I ordered a second main board. Didn't fix it. Defective board? ok
the 3rd one is also defective??

It seems that maybe.. just maybe there is something else going on? Davi.p brought up the LVDS cable? is this something that I should investigate further?
Moving the connector / board does seem to improve things at times. Though it could be BGA issue as well. Should I just sell the power supply and other parts and move on, or is there something I should / could try?
Thanks

Can you please elaborate on this LVDS cable issue? replacing cable could do it you think?
