SOURCE: I cannot find hdtv channels on my viewsonic n1930w
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.

Hi,
This kind of problem related to bad firmware saved in ROM that is part of main board so main board will be rpelaced to solve this issue.
It has nothing to do with power supply board that was replaced.
I'm not sure if main board is available some where as I could not locate it.
Thanks.

I had the same problem. It appears to be due to a bad tv tuner. Turn on your computer and leave the coax unplugged. Leave it for a while (15-30 min). When you see "snow" on your screen, you will be able to use the source button to change to another input and see if you can get a signal. I am running my cable through a dvd recorder and using the AV input to watch tv. Also, my HDMI, component and RGB work fine. After thank don't try to access the TV source until you have had your tuner replaced.
