As you look from the back of the set it is inside the large metal box on the far left of the set. Several plugs and a few screws and it (the entire box pulls out-it is plugged into a large set of sockets.

Before you remove it let me know what problem you have.

Ws-55511 green light changed caps. where is pico fuse located ?


There are at least two pico fuses in the DM unit along with the caps; DM is large metal box on left as you look from behind.

Blinking green light that does not stop means problem is in DM unit that is not booting up.

If you have questions let me know.

Ws-55511 replaced all 7 caps in the dm, still wont power on


I have seen this only 2 times----you may be able to unsolder and remove the reset micro switch---you have to remove the whole screen to get at it---the micro switch board may not be available---the switches can be tested with a ohmmeter set to high end and of course should not have a reading across them--I bet the reset switch is bad--you can remove it and put the keyboard back---most of the Mitsubishi sets use the same type of switches--Only other thing is leave the keyboard disconnected and just use the remote.

Glad you found the problem.

Ws-55511 DM 5volts draged down blinking led


Hello,

Did you check the caps on the DM board? They usually go bad after a period of time. Remove the DM board and the metallic cover and there should be 4 to 7 capacitors (There are different revisions of the DM board). Check these caps also, replace if needed.

Thank you,
