Question about Mitsubishi WD-52525 52" Rear Projection HDTV
I have the blue flickering screen problem with my wd52525. I disassembled the electrical chassis and found 4 bad capacitors. I have ordered enough to replace all of the potential trouble capacitors because I don't want to have to do this again.
After I replace the capacitors I will try to reassemble the tv but to tell the truth, I'm not real confident, lol.
Is there a detailed description for putting this thing back together? If not, it may end up in the landfill!!!
If your going thru all this trouble, be sure to check the 4 capacitors on the DM board (1000mf/16volt), the 4 caps on the formatter board (1000MF/16volt) and the 2 caps on the power supply board (3300mf/10 volt) Mitsu recoomends changing the 1000mf caps to 680MF/16volt.
It is kind of a pain to change these.

Tips for a great answer:
I had a similar problem. I had a 52"
RCArear projection tv. It
would do this when I initially turned on the television, but then after a few
"on/off, on/off, on/off" cycles it would stay on. Eventually it
started doing it more; until finally there was a spark and that was it. The tv
was dead.The bloggers called it "the blinking green light of death" (because
of green light on the panel).The
power board is going out.ALSO holding down the Input and Menu buttons afterward will give you
some diagnostic information via 2 sets of blinking indicator lights.
You may very well have issues with capacitors on this set being that it is or very similar to the V26 chassis. Since I have spare test lamps laying around, I would normally try that first. If the lamp still would not stay lit, I would then suspect the electrical chassis (capacitors). When I suspect the chassis, I can usually verify it by pulling it out and partially disassemble it and find blown capacitors
