N3250w fix did the replacement board fix the problem?

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......

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.

part or repairs in uk ohm supplies

you may have a bad inverter board. check for 24volts to the board.

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.

You may be able to fix your device by re-touching all the solders on the video in/out board.
good luck

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 have the same model and same problem. i found a listing for a control board at the viewsonic online store. here is the link:

i also called viewsonic parts at 1-888-881-8781, and they said they still make parts for this model.

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.
