Hi all, this sony has severe pincushion problem, R571, Q505, C535,
C548, D508 have all been changed,
Q504, D506, D507 check good as do all voltages on pincushion IC,531.
Problem is R571 and Q505 are still
running extremely hot, voltage on collector of Q505 reads -7.2v
schematic calls for +14.3?? collector of Q504 reads positive 9v,
schematic says -9v, I noticed that schematic says emitter of Q505 should
be +16 and that has to be a mis
print so I`m a little skeptical of this print, can`t run set more than a
minute or two because of heat problem, any
ideas?? TIA
