Green Blinking light of death?

Go through the above mentioned details if you notice Green blinking light of death on your television.
This information applies to Mitsubishi sets that have a Model number beginning with VS, WS, WT etc. It does not apply to the WD series of sets made later.
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 keyboard 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.

There are sites on the internet selling a "kit" with the caps etc and instructions for replacing them---if they are bad the silver tops of them will be bulged up and not flat.

The above mentioned details will help you know the problem better on your television.So you can take a step forward in taking a decision in getting it repaired by professional or doing in yourself.

Mitsubishi PIP module BYPASS ?

Read the procedure as follows for PIP module bypas
The details as as follows :---
This applies to most Direct view and some projection sets made in the 1990's.
While it is possible to repair in some cases this problem it is quicker and cheaper just to bypass the module--you will no longer have the PIP function.
Here are the bypass instructions:
1.) With the set unplugged remove the back cover and locate the PIP board to the left side of the set--one wire (usually green) is soldered to the metal shield. Unsolder the lead and set it aside.
2.) The board is plugged in and you will have to release the two tabs at the bottom to pull it out.
3.) Locate the pins on the large plug (should be 12 pin) on the bottom of the board.
4.) You need to CUT the copper foil traces with an Exacto knife on pins 5, 7, 9. and 11 near the plug so they are no longer connected to the plug.
5.) You install (on the bottom of the board) a 4.7 mfd filter cap with the + on pin 7 and the - or negative on pin 9.
6.) You install (on the bottom of the board) a 4.7 mfd filter cap with the + on pin 5 and the - (negative) on pin 11.
7.) Reinstall the PIP board and make sure the caps do not touch anything near that board; solder the ground wire back to the shield.
The reason the board fails is because the surface mounted caps dry out and or leak onto the circuit board---there are a lot of them.


I have seen shops replace some of the caps and get it to work but sooner or later more go bad so usually it is better just to bypass the board and not have the PIP feature anymore.


The above mentioned details will help you out.
