Samsung DLP TV shuts off

I fixed the problem. The unit turns off because it gets overheated. You can use a cheap external fan to blow against the casing for the lamp and TV no longer shuts off. I just had it on for 5 hours asnd it did not shut itself off. This is very simple solution. No need to mass around with parts etc. Sunny

Just like FixYa said, a memo from Samsung on how to correctly shut the light door fixed my problem. I have had over 8 visits from repairman and everything was replaced, including bulbs and the entire light engine. I took the door off and replaced it correctly and as of today it has operated a full week without ANY problems. Before it would shut itself off 3-10 times per nite........Thank you FixYa.

i posted within the last month or so on this issue. Best Buy, with which we have an extended warranty luckily, sent out a new tech - tv was replace by Samsung in the 1st year and lamp replaced on new set twice since. still no resolution - now this time the new tech replaced both the lamp and the ballast. so far so good but historically it will take another 6 months for it to malfunction again. we have 2 years to go on warranty luckily. the techs - none we have dealt with - seem to have a good handle on the cause so don't know how to cure it. the lamp door is not a possibility on this model from what i can surmise. it is designed differently than the model that is known to have that issue. the lamp "engine" noted in another post is a new possibility that i hadn't heard of. i will save that info for the next tech - which is guaranteed to happen.

A samsung service tech came out and said he was very familiar with this problem. He changed a small part (it took one minute) and the problem has been corrected. It had nothing to do with the fan.

I just replaced the bulb and I am now have the same issue that you have. I have removed the bulb right after the tv turn itself off and found it very hot although I didn't have my pyrometer to take actual temp readings, sorry.

I then reinstalled the bulb assembly and rigged the back sensor to sense 'closed' cabinet and then looked/felt for fan movement. Both the small fan (I will dub processor fan) and the large lamp fan is moving but to me the lamp fan doesn't circulate enough air to sufficiently cool the bulb.

I am here looking for answers however I will more than likely rig a 4" pc fan on the other side of the bulb to pull air across the bulb. I believe that this will solve my problem. I will use the same wires that feed the other fan minus the sensor wire.

I have a different model of the Samsung DLP TV but looks the same. My tv was doing the same problem. My standby light and lamp light somtimes blinks while the tv turns off, but some times it just shuts off with no lights. The problem is its over heating... Easy problem to fix.

1. Unplug the t.v
2. Put on some plastic, rubber or latex gloves so you dont shock anything
3. Remove the lamp cover
4. Remove the big cover that covers the back of the t.v.
5. You will see a small fan and behind that is a heat sink.
6. Remove fan but don't unplug it.
7. Clean all the dust off the fan and heat sink and any boards you see covered in dust. Use a dust off can or use a cloth but be carefull.

Note: The tv has a heat sensor in it and when it detects that the tv is above operating temp it will turn off.. Dust stops it from cooling down and keeps in the heat which overheats it.

8. Screw the fan back on to the heat sink
9. Replace all panels taken off. If you don't the tv will not turn on
10. Plug you tv in and turn it on...
11. Every thing should work normal now

Note: If you had color or picture problems these steps won't help that. Best to call Samsung for those type of repairs.

Hello All, I may have an inexpensive solution to your problem. I had the same problem with my TV as well. It would shutoff by itself about an hour after it was turned on. The when I would turn it on again it would shut off after 5 to 10 minutes. Finally I got fed up. I knew it was not my bulb because the picture still looks good. I did here a buzzing if I would turn the TV on right away after it would shut off. That was do to the bulb recharging itself. I noticed the TV was extremely hot in the back. So automatically I thought it was the cooling of the set. All post I read keep saying the TV would last about 2 years to a year after a service. Which would be right because (most) service repair clean out the units before installing new parts. What I did was I opened unplugged the TV from the wall and opened unscrewed the back panel door. I used my Air compresser and blew out all the dust inside. ( A can of compressed air should do the job if you do not have a compressor) I removed the bulb and blew out the dust on the bulb as well. I did not remove the bulb from the housing unit. After I dusted the bulb and housing unit I reinstalled it. I keep my home clean but you should have see all the dust that came out. The dust covering the components overheat the unit which causes it to shutdown. It has been about 2 weeks and have not experienced any problems since. All I can say is give this a try and maybe this will work for you. This will only cost you about 10 dollars and 30 minutes of your time. This is better that Hundreds of Dollar in repair.

I have a 61" Samsung DLP TV that is 2 years old. For the past year it has been shutting off at irregular intervals. Sometimes only after an hour of use and sometimes after 2+ hours of use. After reading on the FixYa web site about similiar problems, I noticed that the room temperature seemed to expedite the rate at which the set would begin to intermittingly shut off. I checked the lamp panel access to make sure that the safety switch was properly set. Since I had never opened the panel access since purchasing the unit, I doubted that this was the problem and it wasn't as everything seemd to be in order. Next I took a $5 10" box fan from Walmart, turned the fan speed on "Low" and mounted it to the back of the TV so that it blew directly into the unit's vented panels. I attached the fan with plastic ties to the back of the set directly behind the vented lamp access panel. I then kept the TV on for 10 hours straight with the gas fireplace cranked up and never once did the unit shut off! So far so good and it looks like the problem is fixed. The additional noise is minimal and only when the volume is muted is the sound of the fan barely audible. I would suggest that if others are having a similiar problem then why not try this cheap solution before spending alot of money trying to fix ta problem that alot of techs don't seem to understand. Since my warranty had run out on the unit, I am very thankful for this low budget solution to what seems to be a very expensive problem to have "professionally" repaired. Good Luck and Thanks FixYa!

We have a 61". Same shut off issues. Service tried twice now playing the replace parts game (we bought the 3 year service deal). Now they are going to take the TV to their shop and in the words of their manager, "start replacing parts until they find a problem" I cannot imagine Samsung does not know what is going on with these TVs. Now they have an LED TV with no Lamp inside. Must have found the issue huh? Now we just need another $2300.00 for the upgrade and all will be well. Thank God for the 3 year service contract. I told the manager of the shop its "HIS BABY NOW" Samsung and their contractors need to get honest (fat chance) and fix the thousands of sets this problem has effected. I am not exageratting, Check for yourself the WEB is full of the same "My TV shuts off for no reason " complaint. Next time not Samsung... next time not DLP... But, I will re-new this service contract till I croak and make these people keep fixing it. They may make some money but dealing with me certainly will not be worth one penny of it. My family and I are using that George Bush cash for a new SONY LCD. Ill leave Samsung to fix this one for the next 25 or so years. Thanks FIXYa. I learned more on this page then in 6 months dealing with the people I bought this thing from.

I have a samsung dlp 50" that was shutting it self off a random times, finally in would not come back on , I just got the flashing lights on the power button , after I replaced the lamp, ballast and fans I still had the same problem , then I tryed one last thing , a power supply and BINGO!! that was it, hope this helps!!

P.S. Do not forget to do a "hard reset" after you have replaced any part ! If you do not know what that is , you just plug your tv in and when you go to power it up " Hold in power button until you hear the beep"

I have owned a 50" DLP for two years. About 3 months ago the picture started getting darker and darker. Finally the picture died. Bought a lamp for $140 and after replacing the old lamp the picture returned for 1 or 2 minutes each time after turning the set on. Tonight I will go home and clean everything out in the back. I will NOT turn the set over to a repair man. Hopefully I don't get electrocuted. My Samsung LCD 37" has worked well for 4 years.

I have a 56" I bought in April of 2007. It shut off periodically and I did the "small fan blowing into the back" thing for a while. This helped but it also blew a lot of dust into the TV. I finally cleaned the small fan on the back and that also solved the problem for a while. Yesterday (11/15/09) it shut off every 5 minutes. I finally took the TV apart and was able to clean the big lamp fan, and the entire inside of the TV. Once again this solved the problem. I would not recommend this to everyone as you must be able to put everything back together, but it was easy enough for me. Don't waste money on service calls when a good cleaning is all you need. One other problem I found....the small blue shut off switch on the lamp door had broken off from it's single screw base. I super glued that back into place easily. Very nice TV but lots of maintenance and the price of replacement lamps makes spending more for the LED model make a lot of sense.
