Vertical line-PROSCAN CTC169 chassis
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... |

After that's solved, you'll need to replace Q4802. www.techdata-kicksass.net |
