My jvc-hd52g886 has a bad picture where black shld appers it is over lapped with red bloches

You have a shorted PCB, which one will require diagnostic work.

Here is the manual http://www.retrevo.com/support/JVC-HD-52G886-TVs-manual/id/279ci059/t/2/, also may need to go into picture advance settings to do some calibrations.

seagoblin28,

If you haven't replaced the lamp you should. If you have replaced the lamp you may just need to reset the unit. Go to my tip at http://www.fixya.com/support/r4168009-change_lamp_in_dlp_projection_tv which explains where to get the lamp at the best price and how to replace it as well as links to additional problems.

Thanks for using Fix Ya and for the great rating.]

when the picture is out see if you can see the lamp light on in the back inside the tv. if its still on you might have a problem with the optical engine. if not try replacing the lamp part# tscl110u

Ur power supply it dead,need it replaced.

Yes that I would check also sorry for not bringing that in frount of the diagnosis.

try the magic focus button

Whites are yellow can be a convergence or color balance problem, and lamp going out could also be a bad ballast board, black spots are usually light engine, could be a different fault on DMD board.

The fact is that when you get all this symptom together unavoidably you have a faulty light engine.

The light engine is the most expensive part to replace, its price for this model is always over $1600 ( I know, keep the heart tablets at hand).

Here is the part for your model: TS-COP7A-SAA-R
