Hello, we've been having problems with seeing the channels on our ViewSonic TV before, but today the auto scan doesn't find any channels at all. What could be wrong? Thanks.

First make sure that the current input Source is set to TV to see the option for scanning for channels. There is a Source button on the front of the TV. (It's on the right side as you look at the front of the TV.) The Source button on the original remote is on the left side below the number keys.There are two RF (coaxial) cable inputs near the VGA port on the back of the TV. The digital RF signal needs to go to the port above the VGA port.
To scan for analog channels, press the Menu button. Then navigate to the TV setup option with the Up/Down arrows. Press OK to enter the menu. You can use either the Auto search or the Manual search. However, the Auto will be faster. You can set your country or leave it to Auto. Navigate to Start and press OK for the Auto-scan. There is a DTV menu button above the Volume + button on the remote. Use this menu and look for the Installation section to scan for channels. Again there is an Auto or Manual option.
Press MENU, use left/right buttons to get to input, then select AUTOSCAN using up/down keys and SELECT/ENTER button. This will take a while, 3-5 minutes. When it finishes, it will default to channel 2. At t.his point, push LIST button to see all stations it found.UP/DOWN buttons will let you select station of interest.
Which make/model TV do you have? Are you watching an OTA signal or cable signal?
On my Viewsonic N1930W, I had a period where certain OTA VHF channels had no audio. The UHF channels were fine. The steps I used to reset the TV: unplug for a while. After reconnecting the power, go to the Tools (Options) menu and then reset the TV to the defaults. Then I did a new channel scan for OTA channels. On my TV, the menu is called Options but the icon is a wrench and a hammer in an X. Thus I call it Tools. The Restore Default option is at the bottom of the list in that menu. The reset command triggers several "Are you sure prompts?" Pressing the Enter key on the remote after highlighting Yes is required. After the reset, I can go to the Channel menu and select Auto Scan after making sure that it is set for Air as the source.
If you post a comment with the details of your TV, I may be able to give the steps to reset your TV.
I hope this helps.

I have a 19" N1932W by Viewsonic. I'll give you the steps for mine. First make sure that your input is set to TV. (Press the Input button on the remote or the TV. (My unit has Input at the upper left of the remote or the farthest right button on the TV.) Press repeatedly or use the arrows to get to TV.) Next press Menu on the remote or the TV (furthest left on the TV or below the arrow keys on the right of the remote). Use the left/right arrow keys to navigate to the Channel submenu (the icon on my TV looks like a satellite dish) and press Enter. Navigate down to the TV source line and make sure that it is set to cable with the left/right arrows (if needed). Then go to the line labeled Autoscan and press Enter. You may see an "Are you sure?". In that case select Yes and press Enter again. Another possible question is what type of channels to search (analog, digital, or All). Select the appropriate choice and press Enter again. Wait for the scan to be completed.
On some Viewsonic models, the source and autoscan options are in the TV submenu. The rest of the directions will be the same.
If you've tried all positions with antennae, booster switch is on, and are sure you have all settings on TV correct, try running an alternate cable directly from antennae head to back of current plate where your co-ax from antennae is attached. That will tell you if you have a bad cable or connection from antennae to plate inside. Just get a piece long enough to go through door or window to current spot where connected. If that doesn't cure it, then it's a head or booster switch problem. You can even by-pass the booster and go direct to TV to see if any better.
Do you mean the VT2430? Viewsonic doesn't list a VY2430.
For my Viewsonic TV, first make sure that your input is TV. (Press the Input button on the remote (upper left) or the TV (furthest right). Use the arrow keys or multiple presses of Input to change the current input.) Next press Menu. Use the up/down arrows to navigate to the TV menu (the icon looks like a TV). Press Enter. Set the type of incoming TV signal (Cable or Air or let the tv figure it out with Auto). Then go down to the line labeled AutoScan and press Enter. You may be prompted to begin the scan or to select the type of channels to scan. Press Enter again after making the selection.
As I see it, your problem has something to do with your remote. I bet you have pressed the "auto search" button of your remote that's why your TV keeps on searching channels automatically from channel 76 down. Here's what you've got to do:
1. Get your remote control 2. Turn on your TV. 3. Press the "auto search" button to stop your TV from automatically searching channels. 4. In case it works, I'd advise you to look for channels manually using the number buttons or the "previous" or "next" buttons. 5. If it doesn't work still, contact your technician or your service provider about it. They are of great help for you!
I always tell people to carefuly read their instruction manual and consult the product tech support before determing that there is actualy a fault with their unit.
If sounds like the tuner module or the controler board for the tuner may be failing, or there is a power supply distribution fault to the tuner section and or its controler. This has to be service by the manufacture.
One of the criteria I recommend when people buy an expensive appliance or TV is to make sure that there is local authorized service. I also recommend an extended warrany for expensive items. The warranty is like insurance. You may or may not need to collect!
