Question about ViewSonic VPW425 42 in. Plasma HDTV

1 Answer

Viewsonic 425 shuts itself off.

I was recently given a Viewsonic 425 that use to be in a dealership.  Well, I'm an electrician and traded some labor for it.  It works perfectly for about an hour or so then shuts itself down.  If I reset it in the back it runs for about 15 minutes then continues to turn off.  Any ideas?  I have basic electronic knowledge.

My Viewsonic N3735W power will not come on.

Hello Carl, check first for:
  1. AC mains voltage.
  2. Open Main line.
  3. Open TV cord.
Then we go to the TV itself,
  1. check for power switch does they feel spongy, sluggish or not operating properly.
  2. If you use a remote, check for batteries.
This is now TV power supply problem. need to open the back panel. Caution this should be done by a tech person.
  1. check the ac line from mains to power supply board.
  2. check for open fuse.
  3. check for output voltage on the main board.
If you see bulging capacitors, check for power regulator. This part of the service requires a technical person. as this point the logical next thing to do if the trouble was not found, replace the entire power board. Replacing the power board is costly. Hope you decide what is reasonable. Replace board plus labor and effort, and a possibility that the TV may not work due to poor analysis. OR call your dealer for service.

Your unit has entered "Burn In mode".

E-Mail viewsonic tech support and ask them how to turn the burn-in mode off. You might have to try plugging the unit in while holding down one of the control buttons (or a combination of the buttons.

Have parts for Viewsonic VPW-425 42"

If these are used parts or from a scrapped set, buying used parts would be a very risky investment.

Broken plasma tv model

The plasma usually has 2 sheets of glass, the outer one sounds ok which is not good news as these can be replaced.
The inner panel is the actual plasma layer and if it is craked or broken it usually requires a swapout for a new panel.

Viewsonic n3251w - no power

A lot of TVs are having their power boards go bad due to a poor brand of capacitor (CapXon usually).

If small problems are noticed with the tv, the solution is to replace the capacitors. However, once the TV gets to the point where there is no power at all any more (not even a stand-by light) then the power supply has to be replaced.

Visit Viewsonic's website or call your local Viewsonic repair shop to get a price on this board. They are usually under $100.

Viewsonic N3000w LCD TV randomly shuts off...

It seems that the power fails quite often with this one burning the Inverter boards transformers. OZ960G chip may not be broken, so try getting a new power from somewhere. Measure the transformers. suppose to be somewhat 5 ohms. tolerance is +-1.5 ohm. of more, replace.
