I have a VS10576-1M and
If they are static and not moving, kida look like someone took a thin magic marker and a ruler and drew a straight line across the screen, then it is the panel and the cost of repair would be prohibitive.

I have 2 ViewSonic N2750w and and they both have black screens
i have repaired several n3750w viewsonics .. that may be similar to the 2750 .. in my case all the failures were caused by the same faulty part in the power supply .. the power supply has a 48 volt supply at about 7 amps .. the design uses a syncronous rectifier .. these are normally not used in supplies with that high a voltage out .. syncronous rectifiers make sense when the output voltage is low .. like 3 or 5 volts .. the parts are designed for that range .. but in this supply an IC is over stressed and fails frequently .. you might hear a chirping sound as the supply cycles thru an overload condition .. i modified the power supply to eliminate the syncronous rectifier and replaced it with a single shottky diode .. dissapation goes up slightly but reliability goes up a lot .. i have written an article on this. if anyone needs it i will try to find it . ..

SCREEN SAYS OUT OF RANGE
I assume that you are using a DVI to VGA connection since this TV dose not have a DVI connection.
Make sure that the resolution are set to the following supported resolution:
1280 x 1024 @ 60 Hz
1024 x 768 @ 60, 75 Hz
800 x 600 @ 60, 75 Hz
640 x 480 @ 60, 75 Hz
Or just make sure its set to 1366x768 @ 60Hz
