I just replaced the power supply board in my Pioneer Pro-200 RPTV with
a new one from Pioneer. When I pulled the board out of the box, the
cover over the HV.ADJ and X-RAY.ADJ pots was not attached, and after I
installed the board, for some reason, I adjusted them, thinking they
were the H and V size pots.
I've got the service manual, but I guess those pots are set from the
factory and I can't find anything about how to adjust them. The
service manual does recommend to disconnect the input signal and
"confirm that the high voltage is lower than 30.5kV." So, I
disconnected the anode cable and checked the voltage at the plug on
the flyback, while adjusting the HV pot, but I have to set it at a
pretty extreme setting to get close to that voltage. Does anyone have
any tips on how to correctly adjust it? What does "lower than 30.5kV"
mean anyway, how much lower is ok?
Finally, if I can get the HV adjusted correctly, how do I then set the
xray pot? Should I just turn it until the set shuts off, then turn
back a bit, or is there a better method?
Any tips are much appreciated...
