Hi all,
I figured it's best to keep TDS series issues in one thread. I have a very clean TDS620A that I bought from a friend a few years back, cal 'd in 2012 and has worked beautifully until tonight.
I was probing around on an opamp stage when I accidentally touched the probe off of the palm of my hand, whether coincidence or not the scope flashed onscreen and shutdown. It attempted to reboot but failed every time.
I learned about the infamous electrolytic cap issues after I bought this scope so I opened it expecting the worst. Even under the magnifier I cannot see a single leaky cap or corroded trace on the board, everything is super clean. I spot checked the ESR on maybe 10 caps with my Peak Atlas and every cap was sub 1 ohm.
Is there something obvious that I'm missing? Any ideas appreciated.
Cheers,
Ruairi
