Just a follow-up on my 1st. gen. PalDVR that started to have occasional pixilation and frequent daily freezes requiring a hard (pulled pwr. cord) reset resulting in two different results - downloads PSIP channel guide data if hard drive was NOT in operation, i.e. not recording or playback, the other condition where an error code pops up stating "Error from Hard Drive requires Power Cord Removal" if the Hard Drive was in operation at the time.
All indications that the power supply was the cause motivated me to order a complete set of 105* capacitors and today did the repair. The results were as I suspected, but a complete set was over-kill. Since the separate power board (Tan) was a simple dual layer board with easy part replacement, I replaced ALL of the capacitors on this board, even though none were bulging. I kept these capacitors for emergency use later if necessary.
The actual cause of the problem was C34 on the Main Board (Green) power supply section - a 2200 uf 10V capacitor with a bulging top. This board is a multi-layer board with plated-thru holes which seldom have clear holes after part removal unless you have a 'solder sucker'. which I don't, so hole clearing requires extra careful hand drilling with a fine drill in a pin vise. Because of this, I only replaced that single capacitor.
So far, there has NOT been a single hiccup doing multiple operations/functions simultaneously. Because of this, I personally recommend only purchase of 3-4 2200 uf 10V capacitors Newark #65R3934
for future replacement - I bought 10 @ $0.946 ea. at that quantity. Cheap future reliability.
I would caution everyone that has seen this problem to get this repair completed before un-repairable system failure occurs - a cheap capacitor replacement can give MANY future years of happy recording, especially when there is no comparable DVR on the market today. Happy programming.
