Shutting off and on...

My TV, 3 years old which had lamp replaced about 2 years ago started to act weird. Couple of weeks ago out of nowhere it shut itself off, no picture, no sound red and green lights off. 15 minutes later it turns on by itself... after 2-3 hours of working it did it again. After couple of days the intervals changed, it got worse. At first when I turn it on, it stays on for about an hour, shuts off for 10-15 minutes, comes back on, stays on 25-35 minutes, shuts off for 10-15 and it keeps doing it all the time-25-35 minutes on-10-15 off... I called service people under the extended warranty, they said over the phone that it was the lamp and it is not covered so they want to change the lamp even though I know last time when it was the lamp TV was turning blue and it wasn't shutting off completely, just the picture... Can you help, please...

I have a Samsung DLP HLS 5086 W that is shutting down after a couple of minutes. The color wheel and lamp were both replaced a little over a year ago. The lamp is a Phillips, and the color wheel is OEM. I...

Hope this helps:

Resetting the counter Once you have installed your OEM replacement lamp, resetting the counter is a very simple procedure:
• Begin with the TV powered off.
• Point your remote towards your TV.
• Press:
• Menu + 1 + 8 + 2 + Power.
• Your TV set should now say "Loading Factory".
• Browse down to "Option" then press Enter (or the right cursor button).
To exit the service menu, hit press the EXIT button or just turn off your TV (remember not to turn on your TV immediately afterward!).
NOTE: The Mute+1+8+2 buttons needs to be pressed down consecutively and fairly quickly. If your TV does not enter the service menu after using this combination, you can substitute MENU instead of MUTE. This seems to work for some sets. Also, the right cursor arrow also acts as the ENTER button, so try it if you're having difficulty with the ENTER button.

TV shutting down, lamp and power light blinking

I would try a new lamp. Lamps have varying qualities & usage conditions may cause varying life spans.So, even though the lamp may be 1 year old I would try a new one first.

Samsung tv is shutting off all the time.

Do you have enough air flow to cool it?
It may be overheating....add a fan blowing into it and see if that keeps it on.If it does put a strong small computer fan in somewhere to keep it cool.

TV on/off

How long is your TV on before it turns off? Check the fans and make sure they are all working. The TV may be shutting off due to overheating if a fan quit working.

If you think the lamp is still good maybe try replacing the lamp ballast.

Tv shutting off then comes on

your lamp is going out, they last around 2 years, on the average, this is easily replaced by you, door is on the right side of the tv, you can take the lamp out, if it has a bubble on it, it is getting ready to go out

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.
