Hi guys!
I am working on a nec jc-2002vma-1 monitor. The monitor came in dead,
q560 the deflection transistor #hpa150r4 was shorted along with q5p0 a
fet transistor. I replaced both. The hot is still good. I have never run
across this setup before , the hpa150r4 is rated at 25amps and quite
expensive. The problem is now with the horizontal yoke attached the set
draws over 2 amps of current. I did a ring test on the yoke and it
passed. I would like to think the ring test is reliable, but I can't
find any other failed components in the circuit. Any help on this one
would be appreciated. Thanks!
