Be sure to keep this in mind... the chart that I linked to above is typical for new caps, some increase is normal over useful life. Caps that have 10 times or more than typical new value are suspect.
I have even seen new (cheap) caps that were about 2 times the value stated on the chart and they seemed to work ok, while higher quality brands usually beat the chart number by a significant margin.

The capacitors I checked measured over 8-10 Ohms some even over 30-50 ohms, the ones that measured only .05-.75 ohms I basically said was good. although since there aren't that many capacitors in the power supply circuit on the Westinghouse TV, I figured I'll just replace all of the capacitors and be done with it. I plan on replacing them with Nichicon caps (the originals were Nippon Chemicon caps.) I put in an order without actually submitting the order and it will be about $15 to get all of the caps ordered for the Westinghouse TV and that price includes shipping.

Hello everyone, I just did a search for the Y-Sustain board I need for this TV (The HP Plasma) and there are a couple on there with buy it now or best offer prices, with one going for $62 buy it now price or best offer and another one going for $74 buy it now or best offer and yet another one going for $94 buy it now or best offer, and I'm guessing that all of these prices are way too high for what they ought to be, so with that in mind what would be a good price to offer if I was to use the "best offer" option to try and get the board? I was thinking $25-$30 or so, and yes all three of these boards are reported as being functioning boards by the sellers who said that they came out of TVs with broken screens but otherwise were fully functioning because they removed the boards from the broken TVs and tested them out in a good TV, and I was thinking $25-$30 because of the fact that they can't guarantee the board's longevity since it is a board that is known to malfunction after a while, depending on how hard the TV is used.

What do you guys think? Any input and suggestions would be appreciated.
