HOT,fly,etc
Was dead. Had HOT shorted.
ordered new HOT, fly, HV block , C522 scan cap, L503 (cap, coil changed
due to past histories). Now powered up with the mentioned pix pulled in
from sides and bowed.
next to fly found open R595 (.47 ohm) Replaced it with a bit higher
wattage, powered up, IC 1504 (8 pin op amp C4558) smoked. Replaced
IC1504, still same. Need input here!
Seems like absolutely no convergence. All the pico fuses are OK. Just
found there are no supply voltages to convergence chips.
Will advise. In mean time, suggestions?
Thanks,
Phil Bader
