Probably a diode. What its doing is going into protective shut down. Check your manual for a schematic.

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 shut off and cannot turn back on


If your tv is around 2-4 yrs or used 6000-8000 hrs,never replaced the lamp before it could be time to replace it.The other most common failure is the board that powers the lamp,which is called the ballast.When its bad it will make a clicking sound or like wanting to turn on.The part # for your lamp is TYLA1000 you can find it here:http://www.discount-merchant.com/Panasonic-TY-LA1000-Lamp-DLP-TV-bare-lamp-p/panasonic-ty-la1000-lamp.htm Good luck and God bless you!

47in dlp tv that turns on then shuts back off


The lamp may be bad or a fan has stopped running. Remove your lamp and see if it's shattered or dark and gray in the center. Also your lamp timer could have reached it's limit. check your manual to see how you can reset the timer only if the lamp looks clear.

I have similar problems. I removed the back panel and use compressed air to blow out all the dust from all the components. Just remember not to blow into the main fan on the right as that is the one cooling the lamp. I don't know for sure if this is the only problem.
Dust built up caused heat built up on the components.

You probably have a defective new lamp. Did you put the lamp door back on?

You need a new lamp. Your lamp have been blown. You can purchase the lamp from rca or other vendors on the net or you local tv store and you can also install it yourself. The lamp is usually located in the back of the tv on the side of the protruding back. Next time you do install your brand new lamp, when shutting down your tv wait for your fan to shut off before disconnecting the power cord. Doing so will shortened you lamp life.

Tv shuts off but power light continues to flash


Unit is telling you something is wrong with circuit. LED pilot flashes when malfunction is detected. Power supply shuts unit down to prevent further damage and/or fire. Leave off and seek pro/tech check out
