electronics troubleshooting help needed

[benzyme]

Is anyone (I know you are, Rivea) handy with an oscilloscope and multimeter? I desperately need help troubleshooting this +36 V/-28 V DC switching power supply. Once corrected, the reward is free analysis as long as I have the LCMS.

#electronics on the freenode IRC network might be a good resource to check out as well.

Normally I'd troubleshoot my own equipment..but down to the electrical component level, I don't have the time nor resources. I have an old Fluke 77 and Weller soldering iron, but that's it.

I'm looking to drop another G or two on a variable wavelength detector, as the RAM on mine is shot. The other one I have, needs
a new flowcell. Just found out today, the FTIR needs a new LCD. I don't know wth is going on..I thought it might've been a power surge, but my flash chrom is fine, so is the uhplc pump.

He has some vids especially about repairing power supplies:

There is something wonderful about him, the way explains things is quite to the hearth, I wish all my teachers were like him.
