Bypassing the temp sensor may cause a FIRE!!! I don't recommend this.

    Having said that, I often bypass temp sensors to test if they are the problem, then I order and install a new one. I would not operate it without the sensor though except to test. I looked at Samsung's site and searched for any schematics without luck. I would suggest that the sensor will be mounted where the set produces the most heat. and be wired into the power circuit. If you see a separate power board, it may be wired to but not necessarily mounted to that board. Good Luck.

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.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Why is my 42" dlp tv turns itself off after awhile?


the power supply is not working fine. your tv needs preventive service so that semiconductor, diodes and capacitors are changed on the power supply before it switches off completely on its own.
do it fast
okay

My samsung dlp tv intermittently just shuts off...don't know if it is because of the lamp or what


When it shuts down, do the LEDS on the front blink? There are 3 of them. Standby, temp and lamp. Do any combination of the 3 blink when shuting down. I could tell you where to start just by those lights blinking.

61" samsung DLP 3 years old. Keeps turning off by itself.


Get a small but powerful used computer fan and place it in the TV to replace the defective old fan.That's the best way.The factory fans in these TVs don't last.

Once before I had this same problem and FixYa gave me the solution. When you replace the lamp door, there is a switch inside so be sure the door is put in at an angle so to hold the switch up. It solved my problem after numerous repairmen missed it.

Samsung dlp keeps shutting off


Could be several things but the most common causes are:

1. Make sure that the lamp is working:
-make sure it lights up as viewed through the lamp access panel or the back of the set and stays lit. New lamps for most units are available on eBay for less than 100.00 with free shipping.

or

2. That the lamp access door safety switch is properly held in place:
-make sure that the lamp access door is in place and that the screw is snug. The symptoms of a bad / broken or open switch is that the unit will light up and the fans will spin for about 15-20 seconds then the unit will power down.

Other notes: A general comment on cleaning the fans... that is only part of a heat problem or preventive maintenance. Make sure you also clean the heat syncs of any dust. These are the fin shaped items... some are black and others are silver... found near or behind the fans. Get yourself a one or two inch SOFT bristle paint brush and gently wipe the fins clean with the nozzle of a vacuum cleaner close to the area to **** up the dust. Clean fans won't do much good if these are coated with dust and most of them are after a few months of service.

I have two 50" units and I clean them every year in the spring... before the heat of the summer hits. Unlike other TV designs, DLP's move a LOT of air so this is important.

Have a 42 inch dlp samsung the tv is starting to turn it self off random. after being on for a long period of time


We have had the same problem with our 42" Samsung DLP - only two years old! We searched all over the internet for a list of ways to fix it. I found several things can help, including a switch that pops to the wrong position, cleaning the fan, etc. I put all the information together in a how-to format because it was so frustrating to go all over the internet looking for ideas on how to fix it.

Samsung DLP TV shuts off


I had the same problem and stumbled on the fix. It seems there is a factory defect. Open the lamp cover and you will probobly notice that the blue shut off switch on the left side is landing on top od the lamp cover. Reach down with a pencil or something and make sure the switch is under the tab on the lamp cover. My 50 DLP has not shut down since I set the switch properly. Free fix... try it.
