This sounds like the engine or the lamps are bad.

61mp1 nec plasma keeps shutting down after 5 minutes, when switch on picture ok

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

NEC plasmaSync 61mp1 problems

Here is the link for the user manual if you need it; Check page 54 of the manual (61 of the pdf) right at the bottom. The lights you have indicate that either the power supply citcuit, the screen, or one or more fans have been damaged. If you are sure all the fans work, then the power supply is the only repairable posssibility. replacing the screen is not worth it. The fact that the fuse blew but doesn't blow again makes me suspect one of the transformers or capacitors in the power supply has blown, causing the short that blew the fuse, but also then melted the short so it no longer blows the fuse. If you have a multimeter, and ideally an ESR meter, with a good photo of the power supply unit we can hopefully talk you through what to check - otherwise get a repair shop to look at the power supply. Hope this helps :)

Cannot get it to change input on NEC

You may have the child lock enabled on the front panel, visit the NEC website to download the owner's manual to your television, search the manual document for the text "child" and there should be a two button simultaneous depression to disable the child lock feature. Check eBay for a remote control if needed.

Monitor displays half screen sometimes and goes back to full screen later. Some days you get the full screen but today it is half screen one time and then full screen another time. It finally quit...

The monitor have problem in vertical section of the board.Maybe the vertical output or any parts around the vertical ic is loose connection circuit,what we called,cold solder so its better to resolder the board at the vertical section.

The screen remained totally black and the italian nec sayd there is non way to fix it

Everything is "Fixable".
I suspect that if there is no light at all, (in a dark room, nothing) then the high voltage is missing, 125Volts or so. All Plasma screens work on a similar principal; power to make the gas flash to produce UV light and a processor producing the strikes of light. If there is light then the upscaler is not working and that will be panel changing as I doubt their engineers will understand how it is fixed.
That is the only two options that I am aware of. Which includes the power supply of course as that is where the voltages come from.

NEC Plasmasync 61mp1 - won't turn on

Its the power supply board. If you cant get the whole board, check your transistors theyre most likely FSXXX-X (part #). Replacing them should solve the problem. And they're only about a dollar each so youll save a bunch too but it requires a little more work.

61MP1 turns off after 5-10 minutes


I have a 61MP1 that wont turn on. I get the green flashing light to signal power but nothing happens with the plasma. You seem to know a fair bit. A guy in UK said he'd supply a new power board for $500 but wants my old one in return. Sounds like it might be something I can fix here. Any suggestions. Barry
