Vertical line-PROSCAN CTC169 chassis

[Ben]

Hi , I'm having this TV 27" eith a "no horizontal deflection" symptom.

I had found that CR4402 (PFR856) RCA #243636 was shorted.

I replaced it and same problem.

At power up , the is a bright vertical white line and disapeared to a small
vertical line in the middle after a few seconds.

I had check the Yoke (H) and seems to be OK.

The HOT seems to be OK also . It's a 2SD1885.

There are also 2 big blue capacitors(.048/250v I think) in the horizontal
section that I did not change but they seem to be OK.

Any idea ?

Tks...

Most likely, C4402 or 4403 are open. After that's solved, you'll need
to replace Q4802.
