Question about ViewSonic N3250W Television

1 Answer

No picture on N3250W viewsonic

I have a 2 year old Viewsonic that when turned on will flash a picture and then go off. It was actually my brothers he changed the main system board which did not solve the problem. I have a background in component repair so he gave it to me to fix. So ok I suspect the power supply and sure enough close inspection shows a burnt component resistor RS1 on the board and possible other items. I would give you the PSU number except I am at work and don't have it woth me but memory said it's the fs?? 212-?? if that helps. all i am looking for is the pinouts for the PSU and if viewsonic and God willing a schematic. I will comment on the PSU unit what I get home. Thanks

I just had a viewsonic supply all apart with a blown capacitor, I believe c36. q7 a surface mount npn transistor on the solder side of board was shorted. Replaced cap and transistor, set works fine. Also, check all your electrolytics on this board as they sometimes swell and go bad.

Unplug the TV from the wall outlet. Press and hold the power button for about 10 seconds. Wait five minutes and then re-apply power.

Viewsonic N3250w. Power supply went out and I replaced the bad capacitors. TV worked for a week then now when I turn it on, the screen just turns on and off


Check to see if the 24vdc disappear when the screen black out, it is always there then you have problem in the backlight inverter board. Did you replace the caps in the 24vdc supply also? I replace the whole set.
