Question about Samsung DLP HL-P5663W 56" TV
I have the 50in version of the Samsung DLP HL-P5663W 56...the TV stay on for awhile and turns off by it self. i can turn it back on right away and some times it stays on for a awhile before turning off and some times it keeps turning off right away.
I have not checked the indicator lights yet but i plan to the next time it happens.
We have a Samsung HL-S6187W that's only a year and a half old that was having the same problem.... it would shut off for no reason... sometimes after being on for awhile but then sometimes it would shut off w/in a minute of it being on. Called Samsung support and they said to unplug and "reset" the T.V. and if that didn't happen they'd send a tech out (at a fairly steep service charge) and they would troubleshoot it. Talked to my audio/video guy that installed it all and he said it was probably the lamp that needed to be replaced (obviously for labor and parts charge). We really don't use the T.V. that much (have another flat screen 20' away in the kitchen we watch more often) so I seriously doubted it was the lamp.... plus it couldn't be turning off from over heating because sometimes it would turn off RIGHT after turning the set on.
After reading several suggestions here on Fixya I incorporated a few options to try and fix it myself and I am ecstatic to report that it's been over a month and a half, and we've watched it alot, and it's completely FIXED and doesn't turn off anymore --- and it didn't cost me a cent to fix!!! WOW!! Thanks to all the suggestions... this is a great website!!
Here's what I did:
1. Took off back lamp cover and vacuumed out the entire area (there wasn't ANY dust... but thought it couldn't hurt to clean it out anyway).
2. I disconnected the temperature sensor and cleaned off the contacts and plugged back in firmly.. (I think this is what the real solution was),
3. I then moved the "Auto Shut Off Switch" back and forth a little then made sure it was in the correct position when I replaced the lamp door cover (it's not hard to make sure it's positioned correctly).
Voila!! It's all fixed! This site has great pictures of the correct way to position the Auto Shut Off Switch and of the temp. sensor if you need it.

Samsung HLR4266wx: My tv was cutting off every couple of minutes. Heard it might be heating up and an automatic turn off function caused it to shut off. Purchased a can of the compressed air that you use to blow dust off computers and blew off all of the vents on the rear of the tv. Also put a small 6 inch at the rear of the tv to blow some air in the vents. The tv has not shut off in 2 days now. Might try not using the fan to see if the only problem was the clogged vents. Try this before you take the set in and they charge you $75 just to look at it.

Samsung is noted for allot of shutdown circuits and sounds like one has engaged, also the switch mode power supply acts up.
I would try PS board first , then HV board.

We have a Samsung HL-R6167W, less than 2 years old. It also started shutting off by itself. The TV repairman said these TV's are known to have problems with the light engine and parts connected to it. He said they used to replace the bulb, then a week or two later it would do the same thing so now they replace the light engine at the first problem. He has replaced over 50 of them. Luckily we have an extended warranty as the cost is around $750-$800. He said all these TV's should be sold with extended warranties.
