Top 20 ViewSonic N2750w 27 in. HD-Ready LCD Television - Page 5 Questions & Answers

The problem is in the set. The remote sensor or system control is not "seeing" the remote commands.

Put new batteries in remote control.

inverter board is failing causing shut down

This TV needs a technician to fix it.

Here is the troubleshooting guide for the error

Hold the Vol+ Vol- buttons down and turn on the power switch in the back of the unit.
The screen should turn blue and some square in the middle of it.
The noisy square is actually the bios being reset.
Once the unit turns itself off, you can turn it back as usual.
Note: Some of these units require a 3 button reset.
In that case hold Vol+ Vol- and Menu at the same time while you turn the power switch on in the back of the set.
I hope it was helpful.

how old isw this set, get a flash light and point it at the screen look very carefully and see if you can see a pic if so then open it up you have a small pico fuse going to your lcd screen replace and that should fix it good luck

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.

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. 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 .

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

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.

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.

Did you ever figure this out? I have the same problem. Thanks for any help you can supply.

hey wats up ok do u have a hdmi cable if u do hook it up and tell me if it's d same

just turn the tv down to minimum volume i don't think there is a way to turn them off

this a problem which has 2 troubleshooiting tips 1st disconnect d control panel if d tv still does not woek it's d main bd

I'd say it's more than likely built into the power supply on this model, take the back off, the inverter plugs into the back of the panel on both the left and right, if not, you can take photos of it with the back off and send it to me and I'll identify it for you

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.

Closed Captioning with text mode is on. Press the CC button a couple times and it should be fixed
