I replaced the bad cap, i recorded all the wires that had to unplug but one . Now I can not remember we it goes on the board, this wire is on the left, it is brown and blue. can any one help me?


ok on the board there are two wires that are identical one is a two wire plug that goes from the far right pins and goes to the upper convergence board. The other one is a three pin plug but only two wires that goes onto the three pin socket on the left and goes to the small AC filter board.I am attaching a pic of the board the red arrow goes to the small lower board on the right side. and the blue arrow goes to the board thats up above the main chassis on the left side.2_7_2013_8_34_30_am.jpg

Tip

Do it yourself Mitsubishi PIP module BYPASS


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.

I have replaced a capacitor, transitor, and a diode as was described to me by repair world this is on the deflection board, now it turns on and works but it has an hour glass shape to the picture the side...


thats a pin cushion problem. I would check for more bad caps on the deflection board or open resistor. Sounds like you had an issue with the retrace cap CL031 and the HOT transformer and possibly the DL030 often if they fail bad enough the circuit board can actually burn through and that arc can travel and cause other items to fail. You may end up having to replace the deflection board to fully fix the issue of pin cushion that your experiencing now.

On my WS-55511 TV, after a power interruption, will not power up. All i get is a continuos blinking green light.I tried unpluging the tv several times, no luck.


Good Day,

LED does not stop blinking after plug in. Check for 12 volts at connect or PF pin 10 and 28 volts at connector PF pin 11, (on the board on the right hand side, but on the left side of board towards the back of TV). If the supplies are correct suspect a problem in the DM Assembly (part # 955C230002). Part is not available for replacement.

Check C9B01, C9B02, C9B03, C9B13, C9B14, C9B17 and C9B18 (1000 UFD, 16V, 105C) on the DM Power PCB located within the DM Assembly. If they are bad or not, replace them all with part # 181P734030 (680 UFD, 16V, 105C).


The DM (Digital Module) Assembly is located on the extreme left of the chassis from the back. It is standing in a vertical position. Remove cover and you see the Cap’s in one corner of the inside PCB.

Good Luck, Big IRISH.

The picture on my Mitsubishi Model VS-45607 is not staying on track and scrolling continually


Good Day,
It sounds like you have a bad cap or IC. Replace C2P05 100 ufd 16 volts, off Pin 3 of IC2P01. It is on the Signal Board. IC2P01 Part # 270P466020 (stand-up type mounted on heat sink). The Signal Board is the the board on the left hand side looking at the TV from the back. The parts are on the right side of the Signal Brd towards the middle and back. Replace it even if it checks good. Look at other Caps in the general area and if you see black stuff on the negitive leg of those caps(replace them also).

Good Luck, Big Irish.

65" Mitsu with 55" DM ?


I would go for changing the capacitors I have seen many that have the same scenario.95 % of the time it falls back to capacitors being bad on the board. I have also seen alot of boards interchanged in the projection units. Has it ever been in for service? If so was it performed byan authorized mitsubishi repair shop?
