Question about ViewSonic N3751W 37 in. LCD Television
Won't complete autoscan when we tried to setup without cable box. have no manual so can't trouble shoot,
Do a factory reset to this set. Just unplug it from AC mains wall socket, and re-plug it after 10 minutes or so. This must make the set to a hard reset.

Try pressing the auto button.
If you can't find one try the + button or
right arrow button, then each other button in turn, one should reset to automatic settings.
If the onscreen display (OSD) comes up see if you can find an auto option by pressing the + or right arrow key

your dvd is set to 480p. if it is a convertable dvd player set it to 1080i. the tv sets itsef to whatever the dvd player displays. if not all dvd is 480 to 720 p. blu ray will get you top notch 1080 display.

There is no service manual available for a Viewsonic. You must trouble shoot it from knowledge. If you need assistance after voltage checks then feel free to re-post.

Check that your antenna is sufficient for your location and oriented correctly. Try antennaweb.org for the most likely channels; tvfool.com has a much greater list of channels and the antennas needed to receive them. Both sites assume external antennas and warn that trees and buildings around your location may cause interference.
If you have a splitter connecting one antenna to several TVs, consider using an amplifier to ensure that the TV gets sufficient signal strength. Remember digital TV is has all-or-nothing reception issues.
If you previously could pick up the stations with this TV and suddenly lost them, try resetting your TV. Unplug the unit for at least 10 seconds. Also restore the factory default settings and then rescan for all channels. The reset is possibly Menu, Options, Restore Default or Menu, Setup, Memory Recall. (Viewsonic has changed its menus at intervals so look for something similar). Once you find it, click enter then left or right arrow to YES, hit enter again. Then hit menu twice to exit the OSD menu and then re-enter the menus before trying to rescan channels.
Also check that the TV is looking for OTA and not cable signals. Check that the tuner is still working by retrying the scan in a spot you know that the antenna captures a stations signal. Make sure your antenna cable hasn't been damaged by anything.
If you recently had a power surge (lightning strike) near the antenna or cable, you may be in need of a new tuner. (BTDT with an older TV)
I hope this helps.
