Hello,

Friend brought this to me, so far I found not functioning IC 651 in
converter board.
Searched the net on this to find out that this is a common problem and it is
hard to find the Sanken chip and not to be taken by a fake (read chip)
replacement.
So far I have following voltages on the chip, with reference to pin 7
Pin 1 168 volts
Pin 2 0 volts
Pin 3 10 volts
Pin 4 0 volts
Pin 5 0 volts
Pin 6 0 volts
Pin 7 0 volts
Pin 8 10 volts
Pin 9 0 volts

Got the datashet for the STRS6301 chip, drew the schematic of the primary
site of the converter, all points bad IC, as I do not see so far any other
problem, HOT is not shorted etc.
Is there anything else that always goes on this set and where I can get the
right part.

Ziggie.
