Question about Mitsubishi WS-55859 55" Rear Projection Television
You have to take the top piece on the left side off w/4 screws. Then there are 2 things that is holding the DM unit in place on the top of it and bottom of it. Take the top one off. This will allow you to remove the DM box. Use like a tackle box or something to hold it up while repairing it. There are some screws that hold the main board in place in the front of it those will need to be removed to allow you to move it out a little.

Thanks for using FixYa. Continuous blinking green LED on Mitsubishi's Projection which normally blinks after a power surge means that the microprocessors inside the unit are unable to communicate with each other. Usually Mitsubishi's Projection TV use 1000uF/16 in the DM MODULE (which is one of the two microprocessors), as these capacitors are too small for the load they get they usually fail usually after about 3-5 years. They might also fail due to voltage fluctuations. To resolve this issue these capacitors should be replaced with 1000uF/25 volt or 1000uF/35 volt capacitors, so that they can handle any voltage spikes that will occur. To do the repair you'll need to take the back off the TV apart in order to remove the faulty DM module and need to desolder the old capacitors on DM board and install new ones. All this is only recommended to be done by someone who has electrical expertise. Please rate the solution if the issue is resolved or post a comment for further assistance.
