Urn on you tv after it goes off
go to front press menu and device at same time
it will recycle and the green will start flashing
count the cycles a three flash pause and than a 7 flash
will mean a bad fan
there is fan in the back that cools a heat sink
it is easy to get to
sometimes the connection goes bad
you can check your fan
dont order one from mit
this is a standard 3 wire 50mm x50mm computer heat sink fan
take yours out and find one to match
cost about 6-8 dollars unless you have laying form old computers
you have to take off the plastic cover in the back no big deal
with cover off yu will see a metal cover looks like a tunnel at the bottom
three screws removes it wires are under
after removal you will see the fan and heat sink
put you filter on the side back on with the two screws
so that the tv will start plug it back in turn power and see if the fan spins
if not check connects no run after that
than replace this fan
mine worked fine with new fan
if need more help you email me at

After power-on, if the green LED does not stop blinking after 70 seconds, it may be either the card reader (p/n # 299P271010) or the DM board (p/n 934C116002).  You could try checking the DM board for swollen capacitors.

Hit the reset button. The light will flash for about 20 seconds.. when it goes out. turn the TV on. That should work. If not. then it may be the lamp

I have a Mitsubishi WD-52725 DLP TV and green light (timer) is rapidly blinking after a power outage and set will not turn on. The bulb was replaced a month ago and it has worked fine since. Now it will...

make a System Reset process. To do this;
If the TV will not respond to either the remote control or the front panel controls and/or will not power Off, press the SYSTEM RESET button with a pointed item like the end point of a paperclip. The TV will turn Off and the TIMER light will flash quickly for about one minute. When the TIMER light stops flashing, you may again turn on the TV. The changes you made the last time the TV was on before you used the SYSTEM RESET button may be lost, however, the changes that were previously saved are not lost.

Blinking Green Light on Mitsubishi DLP 52525

the dlp will most likely need a qualified mits repair center to take over for you. repairing that set is pretty involved. and the parts you would need are not available to the public.
on your 48" CRT projection check the DM module for 4 vented 1000mf 16v capacitors. replacement should get you tv working great
