Hi all, Just found out about this group and I hope you all can help me out a little. I bought a 2215 off ebay (and subsequently got my $40 back no questions asked, so not only did he know it was broken despite listing as used, free scope!). Anyways, I started to troubleshoot using the service manual, since the scope just hummed and no trace was provided on the screen without any amount of fiddling, and I tested the voltages on each of the test points and none were anywhere near the acceptable range (ex. the 30v rail was at 5v...) So I am assuming this is probably caused by bad caps in the psu? Any further thoughts or troubleshooting steps are appreciated.
