MITSUBISHI PIP BY PASS
It is possible to repair most of these but damage from the leaking capacitors can sometimes make this tricky or impossible-
Here are the bypass instructions:
Remove back cover and locate pip board to the left of the set--one wire (usually green) is soldered to the metal shield.
The board is plugged in and you have to release the tabs at the bottom to get it out.
Locate the pins on the large plug (should be 12 pin plug)
You need to cut the copper foil traces with an exacto knife on pins 5, 7, 9 and 11. They need to be free of the board.
You install a 4.7 mfd filter cap to + on to pin on 7 and negative lead on 9.
You install a 4.7 mfd filter cap to + on pin 5 and negative to pin 11.
It should only take a few minutes to do this. You will have to remove the board from the set. I have done this a lot of times--Mitsubishi gets 30 dollars for their instructions to do this and no longer sells the board.
The reason the board fails is all the tiny surface mounted filter caps start leaking and fail.
