Question about ViewSonic N3251w 32 in. LCD HDTV

1 Answer

Viewsonic n3251w went bezerk!

I was playing with my ps3 when out of nowhere the sound started to go up until it reached max. Then i tried lowering it with the remote and still went up. I took the batteries out of the remote to check if it was a bad contact in the remote and it would still do the same thing. I turned it off and would not come back on. I unplugged it and replugged it. it came back on but started that volume frenzy again. Where should I start looking?

The button board or the IR board in the TV. A stuck button can cause some strange behavior. Typically, the TV has 3 control lines: POWER BUTTON, FUNCTION BUTTONS, IR (Remote). Try disconnecting the button board, it should have a connector right on the board. If that fixes it, you can leave it that way or try to find a replacement board (not sure where you should look). If it's the IR board and the button board is daisy-chained through it, you will need to either replace it or repair it. Most often the little receiver is bad when there is a problem with this type of board. You may be able to find a Receiver IC, but just know that it has to match the TV. I hope this was helpful and points you toward your destination. Best wishes.

I was playing my xbox 360 on my viewsonic tv and it just went off


From the symptoms it sounds like the TV requires an Inverter PCB.

This is the part that "lights" the screen.

I hope this helps.

Viewsonic n3251w not power on


Do you have sound? If your have sound then the mains are working correctly but the High voltage to the screen is not. The screaming sound like the High voltage is shorted or at least drawing very excessive current. In either case the power supply for this unit is specific and made by JeanCo in Taiwan and good luck finding a supply. The LCD modules are made by CMO and they have an office in Califronia and might have a power supply.

Good luck!
