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.
ManualsLib has the manual for the Viewsonic N3246W here: https://www.manualslib.com/manual/306714/Viewsonic-N3246w.html. See page 23 for the start of the analog TV channel scan information. See page 30 for the digital TV scan.
I hope this helps.

(For any channel provided by a set-top box, you will not be able to use the TV to store the channel lists.)

Hi All
I have the PFM-42V1E with DVI and SVGA inputs only.
I have a special lead that you can get with scart one end and SVGA other - perfect. It also comes with video sync and a little transformer - this is why you have no picture!
Try looking for SyncBlaster cables - there must be many suppliers / variations but i got mine at www.keene.co.uk
Be warned though a good cable will cost you 50-70 GBP.
Hope it helps
SOURCE: power lock enable
To get rid of the power button enable you need to either press and hold the power button on the tv ( not on the remote control pad) for approx 15 seconds or if that does not work do the same using the source button
SOURCE: ViewSonic TV sound but no picture
If an LCD TV has sound but no picture do the following:
Use the source button to ensure that source is not set to the wrong input.
Try unplugging power cord for ten minutes, to ensure it is not a setting problem.
Check all the video cables at the back of TV.
Check Light /Color settings.
If problem persist and does not depend on external receiver or settings, then it is likely an internal fault.
If it has sound but no picture then one of the following parts is faulty, and must be tested and replaced:
Theinverter is the high voltage board that provides variable power to thebacklight lamp. This is the most common. When inverter is faulty youcan get no picture, or a very dim picture that can only be seen bypointing a torch light with a 45 degree angle on the LCD surface fromvery near distance.
The inverter must be tested by reading voltages with a multimeter.
The LCD ribbon cable/LCD display and connectors.
Thisis quite uncommon, but happens. If the TV had been hit or moved the LCDcable may have slipped out, or the LCD connector may be damaged.
The LCD controller board.
Thisis the board that controls the video signal, it is difficult to test,as there is need to read determined values on IC pins. To test thisboard you need to purchase a service manual and follow thetroubleshooting diagrams on service manual.
Input/Output Signal boards.
This are the boards where youconnect the video and audio cables, if a signal board is defective,then you may get no picture on particular inputs located on faultyboard.
If under warranty contact the manufacturer ringing the number on the user manual.
If you want to repair at your own expenses, just locate any good qualified repairer.
