HELP !
this dog is really bite'n me
I repaired power supply usual C4102,C4105,C4108,CR4118,C4143,C4145.
When powered up R4719 at C-Q4705 on/off switch smoked and found Q4702,and
CR4401 damper shorted,
so replaced those and C4401,C4402,CR4402.
Now U4801, Q4802, CR4401 blows their top when powered up if yoke connected.
Standby volts +153, +7.4, +13.5,+17 and -17
Will come on and run if leave horizontal yoke disconnected.
Run voltage +143.3 others ok except +26v off T4401 pin 10 reads +36v
now needs U4801,Q4802,CR4401,CR4805,Q4804
Have tried subbing different crt/yoke with same results.
Please anyone that may have seen this or have idea my ears are open.
TIA
