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

Look at the power supply first; look for burnt parts, bad capacitors, etc.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

This failure might not be in the power cord but the internal power supply. If your LCD is older then 15-18 months for sure it needs a power supply replacement.
Symptons of a failing power supply are:
1- Set does not powers ON.
2- Turns OFF by itself.
3- Needs to be unplug to make it powers ON again.
4- When the set is ON, it produces a humming noise through the speakers.

You can find a power supply replacement visiting this website and you should be able to replace it yourself.

The defective power supply module will cause the following symptoms:
No Display and no Sound, Then Power indicate light changes from Green to Red.
Turns OFF by itself.
Needs to be unplug to make it work.
Works for a few minutes then turns OFF.
I repair these power supplies, if you need further assistance jah2mil@hotmail.com

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.

No codes available. Get a separate remote to control your cable box.
Viewsonic has issues.

Do you get a red standby light at all? If not, I'd look first for the standby transformer as being defective. There may also be a fuse right by the AC power cord. Look around inside and update this with your results. Post whether or not there is a standby. We'll need to go step by step on this one.

Ever get a resolve?

Got the same problem for a N3250. I'm not an electronic engineer and will attempt to fix my TV. Therefore I got the FSP2123F02 ($49.75)and now they have a harness 4WT0062302GP ($8.90) that will do a quick plug and play and will avoid any solder of the pins. That is my understanding can anyone corroborate this procedure. By the way I got both products from electronica-usa.com
I repaired it on June 28th with the lsit of parts above
More deatil information here (of the problem) http://forum.eserviceinfo.com/viewtopic.php?p=149367#149367
