change the 4 100uf capacitors on the DM board. You will need the service manual to get the set apart as its technical. But with the service manual and take notes you should be able to repair it. But the service manual for that chassis is mandatory or you will never get the chassis out without alot of trouble. Heres a link where you can get the manual emailed to you.

SOURCE: Our Mitsubishi WD 52525 goes to blue screen and shuts off.

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

SOURCE: flashing green light and tv will not turn on with

THIS IS MY STANDARD ANSWER TO THIS QUESTION==SOMETIMES PEOPLE DO NOT TRY THE EASY POSSIBLE REASON--IF YOU HAVE ANY QUESTIONS LET ME KNOW---IF THE ANSWER TOLD YOU something you did not know--rate the solution----

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard2.gif of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.


Let me know what more information you need--I am here to help.

Power light blinks three times then nothing


A green LED that blinks On and Off is an indication on some models that the TV is receiving commands from a remote. By modelling, it just check SYN, SYN-ACK signal between transmitter and receiver. No worries.

Find the settings menu in the TV. It sounds like you turned the green off completely. You can usually set the hues and colors and adjust for your preference or for lighting and such. Hope that helps.

Continuous blinks of standby light indicates a fault in the IIC data bus. The main board is likely to be faulty. If you wish to know more Check this link.

I fell asleep on my Emerson LC320EMX 32 hdtv remote; when I awoke, the tv was flashing ONLY colors (red, black,blue,white)...Now, How do I get it out of that mode....I was told its stuck in set-mode ?


I had this problem with the LC320EMX, after extensive searching on the internet, I found a solution. The TV has entered some kind of test pattern, to escape from the flashing color test pattern do the following:
While the screen is changing from red,green,Blue,White, & Black, and is Unresposive, Take your factory remote, Press the up arrow, then the down arrow, then (ON THE TV) press the power button. Turn the set back on and it should be functioning properly. (BTW: the set gets into this test pattern if you press too many buttons on the remote, or if you use a universal remote with the wrong code)

It sounds like the key on the remote is stuck. In your case, if you see the flashing light on the camera screen without pushing any button, then for sure one of the button is stuck.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Only half of my 322 receiver is working. I can only acquire signal to one TV.


Make sure u use the other remote to turn it on. Check your LNBF for signal. Make sure your blue light is on, on the receiver itself. You cannot use the green button remote to turn the blue light ON??

Green box keeps popping up in upper right corner


You should be watching your dvd's on an input and not on tv analog 3. Every time the tv "senses" a signal change in the audio that screen will pop up. Connect the DVD player to the tv by using either the red, white and yellow (composite) connections or using the green, blue, red, white and red (component). Once you are on an actual input that box will stop popping up.
