Got this Proscan 27 inch, with no start problem. model ps27400
(ctc-187an4).
Want to start, I can hear it, but makes a puff in audio and cycles 2-3 times. Hot is good, solder is good, caps are good, new vertical does the same, remove the audio, still same. found no shorts anywhere, check all diodes, ok. I got momentarily voltage after the STK. so I presume it is good. What am I missing ??

Proscan is now fixed , running good. YOKE was effectively GOOD.

Problem was diode CR4401 , probably leaking. It is in yoke return path just after return caps.
I did was skeptic and my feelings were right !!

To be put in your database/hints for CTC187.

Thanks all who help by sending their inputs.
