Question about ViewSonic N2750w 27 in. HD-Ready LCD Television

8 Answers

No picture but audio OK

I've had my n2750w for couple of years and just recently while watching the screen would go completely black. i would turn it off and back on and it would work again for few minutes. Now, when i turn it on, a picture on tv comes up for maybe a 10th of a second and goes all black. I can hear the audio but no picture.

Any ideas what the problem is?

    hye I have exactly the same problem

  • apollobc May 02, 2008

    I have the same problem, the tv went out of warrant in January (2008). Picture for about a 10th of a second, then black screen (no raster or images faint or otherwise). Sound and all other functions working normally. Set is also cold, use to be very warm on top. Just wondering how it can have a picture momentarily, indicating that it is capable of producing a picture but something is switching that ability off??



    ViewSonic was very helpful?? "We're sorry your warrenty has expired". That was the only information they where willing to provide.

  • bugeisha36 May 19, 2008

    Ditto here ... I still get a picture for about 20-30 seconds, then it goes blank but audio is fine. Looked around in menu settings but can't find anything.

    Then the audio didn't work at all, finally no power. Everything's gone.

    My 2 year old Viewsonic N2750W just went black in all input modes. Audio on TV input works fine.

The B-00008166 is in fact the main power supply board and is the same one in my N2750W. I shipped it back to Viewsonic today. I did strip down my panel to the bare bones. The inverter is attached to the panel. Long board apx 16" x 5" and has two cables plugged in to the board. When I get the inverter out I will continue to pursue getting a replacement. I did find another website offering inverters http://www.lcdparts.net/LCDTVInverterdetail.aspx?InverterOriginal=4H.V0708.001.

This board looks close to what is in my 2750, but I want to get it out and compare it in more detail. Just have not had the time yet.

I will past a follow up.

Are you guys sure the p/n# is B-00008166???
I think is B-00008116 for the PSU.

Posted on Nov 11, 2008

  • 2view Nov 12, 2008

    Can any body confirm the inverter p/n# for N2750W?
    Or the inverter is part of the PSU circuit?
    i check on VS web site B-00008166:
    Main Board
    Part Number: B-00008166

    Compatible with: VG721M-4 VG921m-4
    So is not the PSU and is no inverter and is not for N2750W????
    Something wrong here!!!


  • 2view Nov 18, 2008

    I was told that the inverter was in B-00008166 well NOT!!!
    So i have to RMA back this PSU B-00008166.
    THE B-00008166 IS a PSU NOT INVERTER!!!!!! crisss!!!

    t53186 the part link from you post seem to be the inverter.
    G that $$$ for a inverter i will try to find a equiv with cheaper or try to fix my board.
    it the XFO i hope?

    for others i repeat B-00008166 is the PSU NOT the inverter.

You have a bad inverter board.I have seen this in quite a few units,various brands.Call electronica 303-322-3037.This is the only place i have found that can supply the part at a resonable price.The part usually comes as a display assy.

No Picture


Backlight Bulb is out.
You cannot purchase these as a spare part, you must purchase the complete backlight.
Backlight cost is more than or equal to a new TV
You may sell this TV on Ebay (list your exact symptom). Start at 100 you will get about 250. Take this money and buy a new TV.
LCD backlights don't fail often but when they do there are no part available to repair them so you get stuck buying the complete assembly part. This is more expensive than a new TV since LCD prices have dropped so much in recent years.
