Try bypassing the the lamp door switch
you can wrap the blue and white wire around the blue finger to hold it back and check to make sure the vents are clean on the back cover for good air flow if it still happens its probably the lamp thermostat

Samsung DLP 72" HL72A650C1F keeps turning off amd on


Hi,
Did you buy the original lamp?
If the problem is related to the lamp door switch, you will get a different error instead of lamp LED.

Do you hear the color wheel spinning?
Again, if it's a color wheel problem the error will be different!
My good guess is the lamp but, it could be the ballast or both.

Best of luck

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...


Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Flashing Green Power on light not picture


Last Saturday evening, I experienced the exact same behavior on my Panasonic PT-52LCX65; it shut itself off without warning. I turned it back on, and it shut itself back off after about a minute, and the red "Lamp" LED on the TV began blinking.

I never got any warning message that the lamp was about to go out, but I've just replaced the lamp and now the TV is working just fine. We had to mail-order the new lamp, because neither H. H. Gregg (where I bought the TV on "Black Friday" 3 years ago), Fry's Electronics, nor Best Buy carries the part locally.

My wife found the new bulb WITH its holding apparatus for something like $120 online, roughly half what other sites were charging. We paid roughly $55 for UPS Next Day Air. The first bulb that was sent arrived broken (some UPS rep apparently thought "Fragile" meant "Shake and Drop"), but the company we ordered from cheerfully rushed us another one, and the second one was in much better shape. (Panasonic doesn't pack these replacement bulbs very well; there's a heavy bulb with a lot of air around it that Panasonic doesn't fill.)

More details available if anyone wants 'em. Hope this helps. -- ChuckE

Tv turns off


Its the lamp that needs replacing. It will run for a couple of seconds and then it would dim or turn off.
