I own a Mitsubishi DLP WD52631 52 inch. I just replaced the lamp and the TV worked fine. I turned it off and the TV will not turn on the red lamp light turns on. I went and pulled the lamp out the next day and the TV worked again. Now to watch the TV I need to unplug the tv to watch it. When I plug the TV in at first the green light flashes and the screen appears red on time green the next any advice on what I can do?

SOURCE: TV suddenly shuts off and lamp light comes on, but lamp is OK

did you reset the lamp timer? just a guess

SOURCE: TV won't come on

Im not at home right now so I can not get the exact part number but you need the powersupply for this set. There are numerous bad capacitors on this board and you might have a blown main on here. Replacing this will repair your set back to working condition.

you have mention that after 10-15 seconds T.V starts up, will you give total description of the T.V within that 10-15 seconds?

that means your lamp it is getting to the end of its life.
sometimes even if the lamp still good the TV will send you that message because that timer is closed to 5000 hours

What you can do is open the lamp door, closed again and the tv will ask you if you replaced it the lamp, and just say yes and that sign will go away

or just simple replace the lamp. 915P020010

YOU NEED TO RESET THE TV. USE A PAPER CLIP TO HOLD DOWN THE BUTTON, AFTER THE LIGHT FLASHES FOR ABOUT ONE MINUTE YOU SHOULD BE ABLE TO TURN ON THE TV.
