[U2] FYI off topic
Dont throw away those flat screens when they die. I fixed one today, 30 minutes and 5 capacitors on the output power supply. They seem to be made with under rated caps. So far since last year i've fixed 9 flat screen monitors, all capacitors in the output power supply. I've change the caps but up'd the rated voltage on each so if it 470uf 10v, i put in a 470uf at 25v. Easier than fixing tube monitors, takes about 30 minutes. Nice side job in the future, everyone will have a couple. Robert ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users

Re: [U2] FYI off topic
Were these capacitors visibly bulging on top? The story goes that a few years ago, a cap provider in China got their mix wrong for the dielectric, and tens of thousands (maybe more) of these caps got put in all kinds of devices. They didn't fail immediately, but a well after the warranty had run out. On Tue, 7 May 2013, Robert Frailey wrote: Dont throw away those flat screens when they die.

Re: [U2] FYI off topic
sounds about right, most caps the cover was shrinking due to overheating, the one today was a 1000uf ar 10 volts, the top wrap was sightly pulling away. The screen had not totally failed but had a 60hrz ripple running to to bottom. most of the caps looked good but I changed all the output, isolated side to be safe.

Re: [U2] FYI off topic
If everyone learned how to fix something, and did it a couple days every week. Maybe we wouldn't throw so much away. Fixing things is how I relax, I hate computers after work. I won't throw something away if it still has value and I can fix it.

Re: [U2] FYI off topic
thanks for the heads up! although i make recreations of vintage guitar tube amplifiers it never occurred to me to pop open a monitor and look for bad caps the number one problem with vintage tube amps are the electrolytic caps in the power filter section. the electrolyte drys up (or oozes out) and starts leaking DC into the AC section of the circuit. i have one out in my shop right now that i'm gonna open up tonight!
