I have an N3250W-L it has the screen White, normal sound.May be one blown fuse in the "T CON" Board?


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

Hope this will help out in solving the problem......

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.

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...


i have the same model and same problem. i found a listing for a control board at the viewsonic online store. here is the link:
http://store.viewsonic.com/html/ibeCCtpItmDspRte.jsp?a=b&item=122065
i also called viewsonic parts at 1-888-881-8781, and they said they still make parts for this model.

ViewSonic N3250w has black line


Unfortunately, my experience with LCDs says that when you see something like this, it usually indicates that the LCD screen is cracked. If you press gently in the area of deformity and it goes clear then returns to black when you remove pressure, it's a tell-tale sign of a cracked screen. Go to e-bay and see if you can get a replacement screen if you're mechanically up to changing it yourself, else an electronics repair shop might be your only hope.
