Question
Hi All
Again sorry I must repost this as well
I went looking for my post in freelists but could not find my most
recent posts??
Anyway
THis set turns on (relay click) then turns itself off almost
immediately.
HB+ =131.6 v
IC 3442 10V in and 5V out
+15VBS ok too!
Chirp of SMPS when plugged into 120V as it should.
Jumper out relay --still no High voltage
If you disconnect the Horiz. Yolk wires the set stays on a little longer
and brief
sniff of audio heard.
H. Out transister tests OK
ideas?
TIA
