Question about ViewSonic N2751W 27 in. LCD Television
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.

As with most LCD screens the two most problems that cause black screen are bad a solderjoint on the inverter board or bulging capcitors, the next problem would be most likely the power mosfets witch break down after time.
