Question about ViewSonic N3250W Television

2 Answers

I need to find a new circuit board for my Viewsonic N3250W monitor. It stopped turning on a week ago and I opened it up and found 2 x circuit boards. They look easy enough to change out and I was wondering where I could buy them.I believe that I could change them out cheaper than finding an authorized repair tech. If this doesn't work then I don't know.

I got the same tv from a friend with the same problem. He didn't want to fix it so I decided to give it a shot. I've done a bit of research and happened to find an individual with way more smarts than I have in the matter, but he did put up some links to replacement power supply cards that aren't through viewsonic so they are in stock as of today and other possible fixes. The cards are a little more expensive, but you can order them now and there's an alternate card that may be more reliable. My particular case has a burnt-out chip that I ordered, so we'll see how that goes. All the credit goes to this guy, here's his link...

    just wanted to follow up and say that the small chip fixed the problem. I ordered it for $20 and soldered it in. the tv is working fine a month later.

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.

No picture on N3250W viewsonic


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.

ViewSonic N3250W will not turn on


check out this website:
http://pagesperso-orange.fr/alain.mionnet/enii3210j.htm

I got one of these tvs from a co-worker who didn't want to try to fix it. I stumbled across this brilliant person's work and ordered the small chip from a place in san fran. it was here in 3 days, i carefully soldered in the new chip (not at all easy, be careful not to pull up the contacts on the circuit board when you remove the burnt one) and the tv has been working fine ever since. only $20 with shipping.
