Samsung CW683CNG
Hi all
I am having a problem trying to fix my Samsung CW683CNG 28" TV. The numbers on the board are as follows: CW683CNG8XXEU HA99-100632B KS3a-AA41-00168C-01 I have checked the voltages coming from the Bridge Rectifier and it is at 320V. REctifier measures Ok. THe voltages acroos the 330uF 400V Main Filter Cap is also 320V. The part I think is suspect is the 3S1265R SPS transistor. Pin 1 has =A320V on it, but nothing on any of the other pins. Does this that it needs replacing? Its been along time since I repaired a TV, although I used to repair computer moniters back in the late 80's/early 90's. I have managed to download the service manual, which, if anybody else needs it, I can email it to them, but I am really suckt on this. Any help, would be truely gratefull. Andy |
