    tottally black but can still get on screen display.

    fault is very intermittant, yet freeze, heat or movement don't appear to affect it. Some days it will run all day others it will come and go and sometimes nothing at all.All inputs are affected.

    I have an NEC PXT-42SV1, probably 1-2 years old, and for the past month
    I would get an intermitten "No Input Signal" whilst watching t.v. This
    would happen if I was watching a DVD, Foxtel or Broadcast free to air.

    NOTE: I have a switch box, as I get confused easily by different
    buttons on different remotes. Everything (DVD, Foxtel, & Aerial
    (using RGB plugs)) plugs into the switch box, and then the RGB lines
    come out of the output of the switch box and goes into INPUT 1 on the

    Tonight it finally died. I turn the NEC Plasma t.v. on, I see the
    friendly NEC logo, it says AV1 (or AV2) in the top left corner, and
    then "NO SIGNAL" "NO SIGNAL DETECTED..." in the middle. It then goes
    to 'screen saver' mode.

    I have unplugged the 3 leads from INPUT 1 and moved them to INPUT 2.

    Same thing.

    I then tried to eliminate the switch box as the culprit by plugging the
    Foxtel leads straight into Video 1 (same results) and then Video 2
    (same results).

    Happy frickin' New Year, eh?

    And I'm due to have surgery and be confined to the house with no use of my hands for 14 days... :(

    Gonna have to call the t.v. repair guy tomorrow and see if he'll come the 30 kilometers to collect the tellie and try to fix it.

    Anyone here have an idea as to what's wrong? I couldn't replace the
    bad component, but I'd like to know if the repair guy is gonna try to
    shaft me.

I need a replacement remote for a nec plasma pxt 42xd2

You can purchase just about any universal remote as a replacement. If you are looking for the original equipment you are looking for part number 301-1P42HB9-01A. You can find it for sale at AWA Parts at the following link:


They currently have 96 in stock and they cost $44.00.

I hope this helps.

Nec plasma problem same as yours

Hi Berni, sorry don't have any good news. the nec guys took the plasma away and it turns out that we needed a new mother board. can u believe it, the plasma was not even a year old yet...Not Happy Jan indeed...
We're still having different problems. there's speckles on the left side of the screen no matter which imput we use. They thought changing the board would fix it but it hasn't. We have extended warranty and will have it looked at soon. Hope you get your working. cookie
