Had the usual 10 blinks shortly after 2years (2010) got nowhere with Panny, bought a new power supply board after spending time reading here, very nice site.
The new supply lasted only 1 year, same problem, bought another supply for a spare when they came available, fortunately, a few months before it kacked again, popped the new one in and away it went, fortunately they were only about $150.
I have another new supply sitting on the shelf, but after spending another day going through this thread from about page 30 to the end, it looked like kdh05 had nailed the fix on the power supply board, incredible effort, thank you.
I did the repair on the original power supply board and will do it to the second supply that died tomorrow, I'll wait until the third board that is in the set dies before I check the repaired boards out, but am confident kdh05's fix will do it.
I removed the mc201 & mc301 modules from the power supply board to do the repairs, which is a lot of extra work, but it's easier to do a good job, I might try to do them in place on the next one. Do remember to place a dab of epoxy or other hardening adhesive from the new cap to the module edge.
I used a radial lead cap, trimmed the leads to connect the -lead to the pad the old cap came off of and the +lead I soldered to pin 13 of the IC, mostly for strength. Laying the cap lengthwise on the module top edge will keep it from being dislodged if bumped.
It would be nice to have a picture of a repaired module on this thread, I'll try to post one after the next repair to let be known what is being talked about here.
It would be nice to have the troubleshooting guide for this piece in case something else goes bad, it's not possible to download from the link Tomwil has posted in the past, but thanks for putting it out there, it's a great set and had the best picture I've seen to date, for $2300, it should, shame on Panny for their treatment of their customers.
Thanks to all who have contributed to this fix.
