Samsung DLP turns off by itself(HLR5678WX)

The TV turns off by itself. Sometimes within a few minutes of turning it on and it may do it several times in before it operates for the rest of the evening. The set doesn't have very many hours on it we use for a couple of hours in the evenings and not every day or to watch a movie on occasion.

SOURCE: Samsung DLP 62 inch turns off by itself after being switched on

take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

SOURCE: 42 inch Samsung DLP TV shuts off by itself. I can

I bypassed the safety switch (it was bad) and vacuumed and blew out all of the dust. So far with this set, 3 years old, I have replaced the bulb twice,it exploded both times, and the color wheel which also exploded! We love the picture but the next time it goes out, it goes out to the trash and I will purchase a top of the line LED/LCD set. No moving parts!!! Samsung designed and manufactured a whole bunch of lemon sets and will not admit it. I have found several hundred complaints about their DLP sets and only a few on other brands.

Possibly a bad light tunnel assembly if the part is only a shadow effect. If not then probably a bad DMD board. The DMD board is part of the light engine but needs to be replaced by a technician.

The tv turns itself off periodically. Sometimes it goes for hours and other times it happens several times in a 5 minute period.


I suspect a bad connection/dry joint in the power supply.
Look for regulator I/c's on heat sinks. They are favourite to get dry joints and anything that is heavy like transformers and chokes.

I have a 50" DLP Samsung that keeps turning off by itself


There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe

52 HD Samsung tv turns off


I have the same problem with my 56" HD Samsung. It shuts off automatically and then on the power button the word Lamp is light up in green. Sometimes I can turn it back on but other times it won't and I have to wait a bit. It's been embarassing a couple times when people were over for a movie. I believe it might be some kind of overheating problem but would like someone to confirm this.

Problem with tv turning off by itself.


I had a friend with the same problem. He had to clean the components and fans in the set. The accumulated dust had caused the set to run hot and a safety switch was the tv off. He purchased a few cans of compressed air and, as he blew the components and fans out, used a vacuum to capture the blown dust. Good luck.

DLP tv trouble shooting


Hi.
Yes it could be a cooling problem, If your tv has any filters remove & clean them ensure fan can turn freely & that nothing can or is snagging it.
