On a Sony SMPS and horizontal output you absolutely must use exact
components. Q601/602 even are of different types and that rating is
also very important, mp,mnp,etc.

Given that you shorted some pins together, you may have some other
failure now that is putting the loads on the smps way out of tolerance.
Might be time to get a hold of Sony's training manual for that chassis
and the SMPS training guide given out at school for that SMPS and
follow the 18 or so steps to fixing the set.
