TV shuts down

The set will come on, then picture will start pulling in on the right side, then shut down in about 20 minutes. I had a similar problem with it about a year ago and found a service letter saying to replace the 2455 capacitor. I did this and unit has worked fine until now. I thought my solder joint may have come loose, so I resoldered it but no luck. I am a very experienced mechanic but a novice on televisions. Any help would be appreciated.

    I thought unit was going into safe mode when it shut down but it may actually be shutting itself off. I have had unit on for over an hour and it has shut off once but came right back on. It will diplay perfectly for a while then it will start pulling in on right side then go back to perfect picture again. It will change channel by itself or pull up adj menu by itself. Someone please take a stab at this problem. The TV guys I have talked to say they no longer repair boards, just replace them. The board cost more than the TV and it's not 4 yrs old yet.

    While going over the hor ciruit I found a small portion of the printed circuit pulled loose from the board near a capacitor. It came completely off on my solderwick when I took the cap off. Unless there is a simple way to repair the printed circuit I am giving up and junking the set. Thanks for the help. At least you sent me in the right direction.

    I have a sharp color tv 27u-s50 that is approx 4 yrs old, and now it will be on for about 45-60 minutes and it will automatically shut off and a white spot appeared in the center of the tv. we had it unplugged for a few weeks then tried the set again. It worked for about 45 minutes then did this again. What could it be? i don't want to run out and buy a new set if it is something that i can fix inexpensively.

    thanks

Try cleaning the little fans that keep the bulb cool, the temp sensor will shut it off so not to damage the bulb , the winning sound may be the fan going bad or not working like it should.

Tv shutting off then comes on


your lamp is going out, they last around 2 years, on the average, this is easily replaced by you, door is on the right side of the tv, you can take the lamp out, if it has a bubble on it, it is getting ready to go out

Standby LED flashes red 4 times with pause then 4 times


You either have a bad fan or one of the rotation sensors mounted on one of the fans has failed. Take the back off the set and see it the main fan slightly right of center is rotating. If it is, there are two more fans, one mounted right above the lamp and another on the optical block itself. You will have to pull the optical block to check those.

Fujitsu 42" Plasma Display shuts off after 20 minutes


This is most likely caused by the Main Power pcb.

See Fujitsu Service Bulletin on this problem in a similar model from Fujitsu. -see link below
http://tomtom2k5.free.fr/fujitsu/PDP-0035-06.pdf

A competent service technician should be able to implement the service bulletin.
A similar service bulletin is probably available for your model. Request bulletin from Fujitsu 'service@fujitsugeneral.com'

Sony KV 20S40 20" tv flutters, reduces in size and then shuts off


The set most probably has cracked solder joints in one of the deflection circuits, which is pretty common. The picture tube and major components are fine. A good tech can quickly resolder the main board and that should not cost too much. If your set came into my shop I would charge about $50 but ask around, the shops in your area will vary.

Samsung DLP HLR5668W has mostly dark picture + grinding noise


Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
