Ya I had mentioned that in my previous email but made a mistake and called

Convergence power supply is running as I have secondary voltages. Tried the
one button auto-convergence and did nothing. Went into menu, all looked ok
there. Something about 220k resistors ? How many are there ? I only saw two
on the convergence PS bd and they are both good. Looks like a deflection
problem more than a convergence problem. Pulse missing from Def to Conv
maybe ?
