Question about Mitsubishi WS-55513 55" Rear Projection HDTV
From all the info I can gather, the blinking light indicates the DM won't boot up. I have pulled the board out and visually checked the capacitors. They all look normal, ie no bulging. I also found while I was tinkering around that the wall plug had a lose fit to the plug which made a intermittent connection at times. Maybe this is the cause of my problem. Anyway, is there a way to check the capacitors prior to removing them? Continuity?
Check three surface mount fuses on trace side of DM circuit

Hi, The header shown to me says green indicator flashing. Fast green blinking is: starting up (will do this for about 1 minute). Slower green blink is cooling down, also 1 minute. Then it should work. Any questions or clarifications..let me know. As for capacitors, they fail as a short or open..just keep in mind that other components will modify the reading.

Yes !! your gonna need a MULTIMETER set to CAPACITANCE to measure it . I also suggest to check for any DRY SOLDER around the power supply & check the CONVERGENCE IC , I believe part num starts with STK and numbers. just throwing in some additional info , hope it helps

Hi, If when you turn on your TV all you get is a blinking green light, you can find a lot of posts about this problem. It usually is caused by bad capacitors in the DM board. If you are handy and not afraid of pulling the DM board desoldering old capacitors and resoldering in new capacitors, this could be done for around $20 - $30. You can look up Mitsubishi blinking green light or follow this link which gives a good discription of the process.
Hope this helps
