WD-62525: My Green Blinking Fix!!!

SOURCE: wd62825 blinking green light
I am also a member of the WD-62725 blinking green light club. I replaced all twelve of the caps I found with higher rated ones and the blinking light problem did not go away completely but I could get the TV synced in 5 or less cycles...for a while. I finally put the TV on an UPS and it did pretty good for about a year until, for some reason, my wife muting the TV would send it into a blue screen and then the dreaded blinking green light of death. I had collected a lot of forum notes and bought the manual (virtually useless) and remembered a post where a guy put a switch on the orange power wire going to the "board to the right of the DM board," as he described it. This was the last attempt for me so I tried it. The board's name is the FMT PWB and on his WD-62825 and my WD-62725 it is the right most board, looking from the rear. Coming off of the top of the board towards the back of the set is a 4 wire connector with one of the wires being orange. Cut that wire and splice 12" long extensions to each leg. Reassemble the TV with these two new wires hanging out the back. Solder an on off switch to these leads. I used and old PC power switch because it had large "On" and "Off" labels on it. I then screwed it to a hole in back with a 1" stand off. Its not pretty but functional. Now turn your new switch off and plug the set in. If it behaves like mine it will blink green for about a minute and then go off. Now turn the new switch to the on position and you are ready to turn on your set. I hope this helps. If it does give me some feedback at rocky_beech(at)yahoo.com. I only need mine to last two more years and my house will be paid for and then I will get the best I can afford. I hope they still have plasmas by then. Cheers
SOURCE: I have no 3.3v, 5v, 10v, 12v in the power supply.
The pico fuses on the power board are most likely blown.
SOURCE: on p.w. board i hvave no 12v 10v 5v 15v supplies i
are you talking about Test points on the power supply?? the capacitors tend to dry out after heat and time and will be less expensive than the board? you can measure a an ohmmeter to confirm.?
