Re: Problems with t935a HV supply


 

I have a T935A that is blowing HV fuse.
It's rated at 62mA but the R458 is drawing 120mA. (I measure it via DMM instead of the fuse, but only turn on the scope for a few seconds.)
This is after I replaced C458 which seems to have high ESR (~30 but perhaps that's not so out of spec either...)
I wonder if it's just a transient response so I should let it run for longer? but I also see that the 50khz oscillation is not happening during the first few seconds either.
Did you come to conclusion about your T922?
