My ViewSonic N3251w TV only displays a blank grey screen. How do I fix my TV?

When I turn on my TV, a blank grey screen appears. The channel number 3 shows in the corner for a few seconds after turning on, but other than that, nothing really works. I have done power unlock and menu unlock. It seems that most things are not enabled. The remote can only turn the TV on and off and pull up the menu. The guide button does not work. :(

There is a button lock in the menu of the television. Using your remote access the menu screen and unlock the buttons.

SOURCE: Powerlock Enable cannot be removed from my ViewSonic N3246w.

I have a 19" ViewSonic and if you hold down the 2nd and 3rd buttons together under the screen, counting from the LEFT, it will disable the Powerlock.

No there are no fuses in that type of flat screen TV. If it will not power on at all then it sounds like a failed or at least failing power supply inside the TV. Unfortunately this is a very difficult repair, and unless you are an electrician I would not recommend attempting it. You will want to contact a local TV repair person in your area if you are sure this is out of warranty, more on that in a bit here. This is actually the most common problem with this type of TV, I see it every day, it just happens - sometimes with new TVs and sometimes it takes many years for it to happen.

If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

If you want to attempt the repair yourself please let me know and I will get you the part number and a place you can purchase it from for what you need.

So sorry that I don't have better news but it is definitely a power issue internally.

Thanks
Tim

I have a n3251 viewsonic and only the sound is working,


With the tv on some channel (and sound working), take a strong flashlight or other light and bring it up to the screen. Do you see a faint picture? Sounds like the backlight has failed. Could be the power supply for it or the inverter board or one of the lamps. Are you qualified to open the unit and look around? Do you have a voltmeter?

I have a Viewsonic flat-screen tv, it displays "menu locked" ??


Try holding the VOL + and VOL - buttons on the TV (not on the remote) down together. You should see a "unlocking buttons" message on screen. This might work. However, I tried it repeatedly, as told to by the Viewsonic "service" rep, and it didn't work for me. Viewsonic is ****, and so is its "service"!

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 will no longer display Closed Captions


You can reset your viewsonic remote control by removing the batteries, and holding the power button down for 10 seconds. Just 10 minutes ago I repaired my remote, which was doing absolutely nothing, not even turning the set off and on, Called Viewsonic, they told me this, and it worked ! Yay !

Viewsonic LCD TV n3251w problem


If the TV will not turn on and you do not have a "red" power indicator light you will need to replace or fix the power module. This is easy to replace, approx 125 USD, but also can be fixed. I fixed mine for about 1.97 USD with parts from Radio Shack.

Powerlock Enable


There are buttons on the bottom of the monitor. Counting from the left, hold down buttons 2 and 3 simultaneously and this will disable the power lock feature. At least that's what I have to do on my 19" model ViewSonic.

Call your insurance agency as this should be covered under your homeowners policy. The main driver board is made by JeanCo of Taiwan and is not replaceable and cannot be ordered as a part.

Good luck
