ViewSonic N2750w dtv input not working

When the tv is set to dtv input it shows only a blue box in the center of the screen (about 1/3 of the screen) and a black background. Nothing else works. The menu comes up and the input menu to allow you to switch to another input. But if you try to use the tv menu it freezes and nothing can work. The other inputs (tv, compnent, hdmi, all seem to be fine). Just the dtv is causing the problem. Any help would be greatly appreciated.

    Mine just died today. I contacted tech support and got this response. I plan to replace the main board if that is where the DTV tuner is. It costs about $375 from Viewsonic. I am wondering if I can get one 3rd party.

Since the unit is already out of warranty, I suggest to visit your nearest local repair shop to further diagnose this issue. They can provide series of test to your unit determine the problem.

    Well looks like I'll be shopping for another TV for the home office. I was looking around to see if I could find the price of the parts, but nwood61 says it's $375 plus labor it seems better just to get a new set. I probably won't go the Viewsonic route though. keep up posted nwood61 if you can get it working again for a reasonable amount.

SOURCE: Picture goes out after 1 second, audio is fine

the problem is not the mian board but the DC to DC inverters that drive the lamps behind the panels some manufactures make them available seperate from the panel but most are a part of the panel. so the whole panel may have to be replaced.

Not an expert on this model but generally if you switch the TV on by pressing the remote's power button it will come back using the input you previously used. If you press a channel button it will come back to DTV.

I am trying to hook up my Dell inspiron 1520 to my viewsonic n2750w tv. Is there an easy way to do this?

Yes there is... You are going to need a VGA cable and an 1/8 audio cable (for sound) - On page 29 it shows a picture of the right side of your computer. You will hook the VGA cable to the VGA port (Number 8 on the diagram).
The on your tv you will hook it up to the vga port as well. Page 7 of the following document shows a pictures of the back of your tv. You will hook it up to "L" on the diagram. Be careful to not bend the pins in the connector.
Switch your tv over to the PC input by clicking the "Input" button. Then make sure your PC is sending a signal, you might have to hit the function key to switch the view.
