You can try removing the 3wire plug that runs to the ATSC tuner (1orange wire 2 white wires). This will tell you if the tuner is causing the shutdown. This is a common problem.

Jvc hd52g886 no sound

l would first make sure the speakers in the set did not get switched to OFF and also see if a DVD connected to one of the rear inputs has sound or not.

I know this set as saw one two weeks old first with no sound.

The entire audio circuit is on a single board (all of it) that is sandwiched between two other boards.

The first one was new so I Called Jvc and did some checks as they indicated---problem was on the audio board and since no individual parts for any board are sold--they told me to order the board--the board was on Factory backorder as a lot of them failed.

The customer did not want to wait so since a new set they exchanged it----Then they notified us to cancel the part order and dispose of the set in any way we wanted--they abandoned it to us.

I had our parts person keep the order going for the board..

l received the part about a month later, installed it (40 minutes) and had a 100% nearly brand new set that we later sold with a warranty--ours.

Most shops should be able to detect if the board is bad---you will have signal and audio coming in and if none at the output--bad board.

If I remember that board wholesales for around (at the time) a hundred dollars or a little more.

Hope this helps

If you are sure that the backlight board is good and that correct power is reaching your board then you might have a problem with the bulbs themselves. Also make sure that the board is grounded.

JVC HD56G887 went out, no sound or picture. Both LED and power lights are blinking

You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

Service man says light engine. how much? jvc model hd52g886

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

If one of the CRT boards is wet, then you have one of the 3 CRT's that is leaking cooling fluid and must be replaced. If the leaking CRT isn't replaced then you will have the issue repeat itself.

Analog pwr board smoking

On this model there were two power boards used, i would look at the srp# on the power board and see if it is the same as the replacement. If you put the wrong one in it can burn up, but usually there is no damage to the rest of the set, just put the correct board in and power up. Hope this helped.
