You will need to have the Screen Control PCB replaced, however as a 27" TV it is most likely 3 or 4 years old.

It is unlikely to be cost effective to repair.

Sorry.

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 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 . ..

Hi
Go here for an invertor you seek. Is from a different make/model, but is the correct part,
Thanks for using FixYa. Good luck with your repair.

There is either a bad color tube or bad cap that will need to be replaced. The caps are about $4 each and can easily be soldered.

Hi. can you list the symptoms so the people here can confirm that the main board is the problem?
do you have the back off of the tv? is it a VS10576-1M?
with a bit more info it may be possible to make less costly repairs .

Yes , point it at your digital camera or video camera and
in the viewer you should see the remote blinking a blush white
light when you press any button . sound like the pads are
dirty ,and need to be opened and cleaned.

This TV dose have PIP (Picture in Picture), Press the PIP button on the remote and see what happens. If fail then I would recommend to call Viewsonic.

ViewSonic N2750w... | Answered on May 14, 2009


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
