Question about Mitsubishi WS-55513 55" Rear Projection HDTV
I have been reading alot of posts about the 65" blink of death. I have also read alot of 55" comes on a few seconds...then goes off. Well my Mitsu 65" comes on for a few seconds then clicks off. I thought I would go ahead and try to replace the caps like I have seen offered as a suggestion for the 65" blink. To my suprise when I pull out the DM, i see ws-55611 on a sticker on the DM. Sure enough... when I open the metal cage...it has seven caps. Should I continue trying to changing out the caps, should I call the dealer and inquire why I have the wrong board? Im probably going to go ahead and try the caps, but If the tv wasn't going on 5...I think would really be t.offed. Thanks to anyone who can offer some suggestions.
I replaced the caps first on my 55" first as well....Then after prodding around with a multimeter on the DM board I found A surface mount 125v 4 amp fuse chip(very small) near the capacitors I replaced that was bad( giving resistance when tested)..On my board the location is labeled fb902 I believe..Test for continuity from one side of the fuse to the other with a multimeter or cheap continuity tester....Couldnt believe I found that tiny problem in the sea of circuits....good luck...Sorry if my terminology sucks but Im a first timer as well....

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?
