Hitachi model #50EX10B - Yes, I posted months ago about this same set.
Sorry, but I still need help. Keeps blowing horizontal outputs. Flyback
primary checked good. Seems like it blows right when the high voltage
is starting to come up. B+ voltage dead on accurate. I have checked
several caps for leakage and ESR, just about every diode, and can't
find a faulty component. Have removed the CRT boards in case of bad
tube, but don't get high voltage. Maybe protective shutdown with no
load? Anyhow, it blows them when everything is connected. Should I be
looking on the primary side circuit of the flyback, or could this be a
faulty load on one of the secondary's circuits? I am close to bringing
it to a shop and paying for repair or info on what's wrong. Last call
on this one. Thanks group.
