42" Nexus NX422 won't turn on.

Hi, I have a 42" Nexus HDTV model: NX422 and i was trying to figure out why it's not working, the light comes on but the screen won't, i opened it and saw a burn out diode inside on the board, i searched what diode i needed by looking at the code on the board and on the diode itself but i cannot find what i'm looking for, i also went to radioshack but they doesn't have anything matched to what i really need, does it really matter what type of diode i buy or not? and where can i get it?

SOURCE: Nexus 42" TV turns on by itself

This is easy and so many people forget about the in built oscilating swivel diode!

It is a static caused effect affecting the remotes receiver depending on what surface the television is placed on.

Cover the zone on the television that receives the remotes signals (just place something in the way of that and the remote but closer to the television) remove the batteries from the remote and hold the 1 button, place the batteries in again whilst still holding one and remove the obstacle blocking the signal.

The signal is reset and the static will not affect again.

As you know the TV is in protect mode because an internal fault has been detected.

I think that you already tried leaving power cable disconnected for ten minutes. After connecting back restart the TV with no device attached.

If there is no sign of failure (bulged capacitors, burnt spots etc.), then the parts must be tested.

There is a service manual for a model of same series here: Samsung Plasma Pn42a45.

Nexus nx422 42" plasma tv picture is grainy sometimes and has shadows. Not even a month old yet. Have HD cables and HD plug running from cable box.


Thanks for using FixYa. As the TV is under warranty, it will be better to get it replaced as opening it will void the warranty.

Please do rate the solution and revert for further assistance.
