SOURCE: NEC PXT-42SV1B Plasma has picture 10 seconds

Sounds like the high voltage power supply is in the process of dying. This would leave the sound unaffected. I don't know if you have a separate supply for this or if a part of the main supply. If you remove the back (after unplugging and allowing a couple of hours to pass), check inside to see if there are two boards with larger components on them. If so, look to see if one of them has more to do with the plasma display than the other; this would be the high voltage source.
This is probably repairable but you might want to check on repair vs. replacement cost before shipping it to anyone.

Are there interchangable screens to put in this model cause mines broken and need another but they dont make parts anymore

you might try Pioneer parts/support

you will need the part# from your panel. Pioneer makes the panels. If you do find the panel don't be surprised at the cost of it. Could very well exceed the cost of a new TV.

I recommend you shop for a new TV.

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.

I accidentally wired up the alternator incorrectly then started the engine and a smoke came out of the backof it now the alt light stays on have I blown the diode it is a hitachi mounted on yanmar 1gm...

Pretty good bet that you did smoke the diode
and a fair to good bet that the alternator is shot
only way to be sure is take it somewhere - a good home town auto parts store - and have it checked

Smoke from the dash a/c control area

it's electrical. u may have to follow the wires back to see if there are wires exposed. if they are just use some electrical tape. tape them up and that should fix the problem. otherwise it's something more and u may need to re-wire the whole thing for ur a/c.

B;owing fuses, wont power up, just smokes


Try checking the reverse protection diode. This diode would normally be connected right after the power connector and would be the biggest diode inside. One way to verify if this is defective and causing the fuse to blow is even with the power switch at the OFF position, the fuse will still blow.

If on the other hand, the reverse protection diode is good and fuse will not blow when power switch is at OFF, then the short/defective component is inside. There would only be two (2) major components that can cause the fuse to blow with the power switch to ON, the final transistor and/or the audio IC.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Wired backwards

Yes Yes Yes. Before anyone tells you different, Yes. The smoke is supposed to happen when you do that. That is a protection diode that fried. It is there for that reason only. In rare cases, more damage can be done, but about 98% of the time it just fries that diode.

You can take it to any cb shop and have it repaired, just tell them the protection diode was fried. They should only charge between $10 and $15 for it. I charge my customers $10.

If you do not have access to a cb shop and are handy with a soldering iron and desoldering iron, I can walk you through this repair. Just let me know. You can post here or email me at

Problem with 160GB HDD

Hi there! I think it's not possible to replace the diode as these components are machine soldered to the board. If a machine soldering facility is available to you, you could possibly replace the diode (choose the same diode model adjacent to the one which is damaged. All the best to u.
