Re: dlp sony

As set is dead the problem is in power supply or horizontal section. though it is a simple &less time taking. but if you have no TV repair experience, or any experience tracing circuit flow with a schematic, call in a tech to assist you with this repair. This tv set is not the place to be experiementing inside of. You probably have bad capacitors and transistors in the power supply or the sweep power supply. Good Luck.

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.

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 HL-R5667W shuts off intermittently

Afraid there is no simple answer to this. This set has multiple things that could shut it down, one may be the balest needs a upgrade , this could be why it seems to be eating lamps. Another is what sounds like a fan is a color wheel , these have known problems of failing, and when this happens sometimes they shut down the set. And finaly does the set have good ventalation, overheating can cause huge problems with this set
