Hi all,
Have been working on a TDS430A that had an SRAM problem, now fixed. Passes self test ok.
But now three of the front panel pots have stopped working; the multi-function, vertical position and trigger level. The horizontal position works ok. All three had been working fine and am not sure now if they all failed at the same time or not, though I don't think so.
I've tried a bit of contact cleaner to see if it was just dirty pots, but this has made no difference.
Anybody else come across this issue and got any suggestions for what might be the reason?
Thanks,
Ralph
