Trouble with my ViewSonic LCD/HDTV NX1932w MFG: ViewSonic DimaniDuo (tm) DESC: 19" LCD / HDTV COMBO P/N: NX1932x Couple of problems: 1) Must turn on 3 times before it will come on, every time. (When I hit the on, it tries to come up with a blue screen, but then goes black, and shuts off completely.) 2) It works fine for about an hour, then I get the blue screen with the message: SIGNAL LOSS - both signals, HD and UHF. If I turn it off for a few minutes, and then do the 3 x's on and off game in #1, then I it will come on again for about 10-20 minutes more. (I do notice that it is pretty hot near the back of the TV towards the top where the air vents are, if that makes any difference. It seems odd that an HD TV would overheat?) Antenna info/background: I purchased $54 radio shack HDTV antenna (SKU: 15-2186) (HDTV Outdoor/Indoor Antenna) and it works fine both indoors and outdoors, but I had to upgrade from the cheaper antenna $29 (circular shapped) that did not work so well. The wait time to get help from ViewSonic has not been helpful, can't get through... Any guidance / assistance would be helpful! Thank you!

Look in your manual for a channel scan entry. It should be an item in your setup menu. What this does is re-scan for all the signals it can receive.
Once the scan is done, it should display all the channels that are viewable in your area

Re:I use an outdoor antenna along with a small indoor back-up.

That is an uncommon configuration. connect only the outdoor antenna, and and use a signal booster inside your home. That will fix the problem.

Here some example:

Philips USA PH61111 24dB Dual Output VHF/UHF/FM Amplifier

SV 9512 TV

Is the antenna the correct one for your environment? Do you have the antenna pointed at the stations you want to receive? Use or to get an idea of the location and likely channels you can receive at your location. Antennaweb assumes an outdoor antenna but is very conservative in the list of channels you can receive. (These may match the limits of the indoor antenna.) TVfool lists the stations and the appropriate antenna that will likely receive each station.

Tall trees and buildings will block the signal. Get the antenna as high as possible. Move the rabbit ears and UHF loop to maximize your signal strength. Then make sure the TV is set to use the OTA tuner (ATSC for digtal stations). (That may mean changing the source in the setup menu.)

Then scan for channels. Move your antenna or parts of it and rescan or edit the channel list. (For some TVs there is a weak signal setup option that will let you manually enter the station number (including sub-channel). Then it will provide the signal strength information as you move your antenna.)

I hope this helps. An amplifier may help you bring in weak stations with enough signal strength for the tv to see them.

SOURCE: I just bought an LCD

Few things,

  1. You will have to go into your menu settings and be sure to select "Air" instead of Cable for your antenna connection
  2. Then run auto scan channel setup to find all available channels in your area
  3. Once completed be sure you are on Input Source TV you should be able to select Channel up/down on the remote to select your channel to view

If you ever see No Signal you are probably on an AV input and not on your antenna input.

I hope this helps

these monitors are tightly held in place by clips. After removing all the necessary screws, use somehing like a credit card to pry open the lid. Just need to be careful not to crack the case, or your hand.

Have a nx1932w; worked fine until this morning; turn on the monitor (using it as tv) the logo is in black and white and it says no signal - can't even get menu button to work.

the most common problem with LCDs today is failing electrolytic capacitors, especially in the power supply section. Look for bulging, leaking, blown or missing capacitors and replace them.

Have had the nx1932w for 4 years. turned on this morning and it only shows a blue screen with message stating no signal. have digital cable and all other tv's in the house work. please advise.. thank you

If the ViewSonic logo first comes on followed with no signal the monitor is okay, check the video cable connection between the monitor and the computer, if okay the video graphic's card may be the problem,or the motherboard, but this is speculation you will need somebody to check the system for exact cause.

My ViewSonic VX910 monitor will not turn on, It just blinks on and off every 5-6 sec

Try unplugging it wait a while and plug it again. Sometimes that cures the problem, but I can't promise you it will. i had an HDTV that did that. I unplugged it for a while, and it never did it again.

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.
