Question about Flat Panel Televisions

Open Question

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

SOURCE: I use an outdoor antenna along with a small indoor

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

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.

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

I cannot find hdtv channels on my viewsonic n1930w hdtv monitor, but it does find them on my vizio 22'' hdtv monitor. Am I doing something wrong

Are you trying to get the HD signal from the roof antenna or from cable? when you set the tuner to scan for channels make sure it is set for 'CABLE' if you are on cable, or 'AIR' if using roof antenna.

Lost power cord

You should try matching up the amperage (A) and voltage (12V) with a universal adapter. You can find at radio shack or walmart. Make sure you get as close to possible to correct amps, anything more than the correct amps can fry your tv. Volts doesn't have to be exact

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.
