Well I did find out what monitor and tv this plasma display was used in. The PX-42M5 is the monitor version, and the PX-42V5 is the TV version, but I called nec and the power supply for the px-42m5a, the only one they know of is $1500. These panels were also sold to OEMS, and I think the one I have is one of those. So now at least I know which retail panel it is. at least I got the part # 74646461. Hopefully another more common 42" panel uses the same power supply.
"I'm sure that's it. Keep in mind, these aren't laptops screens. How many 42" NEC Plasmas could there be?"
I don't agree.
Samsung, Panasonic, NEC, Sony, Sampo, Hitachi, Akai, Fujitsu, Pioneer, Benq (just a few I found real quick) all have 42" plasma panels.
You think every manufacturer makes their own panels? Imagine the cost if that were the case.
Its very well known in the pc industry that most of the components are made by a hand full of manufactures and rebagged with the brand Sony, Pioneer etc.
Same goes for the panels, lcd / dlp / crt projectors and other electronics. Im sure you've seen some projectors at www.projectorcentral.com that show on the bottom, "also manufactured as" which is a rebagged pj and there is a $500 - $1500 price difference.
Its all a scam!
Even tho it was confirmed that this plasma panel came form NEC, it could still be in other plasmas, cheaper or more expensive ones.

Ok, let me put it this way. It says 4203 on there. They guy told him it was a 4203. It's 42 inches. It has NEC chips all over it. Don't you think that it is HIGHLY likely that this plasma is an NEC NP4203MF02? Ok, maybe it's different. Maybe it's the NP4203MF01, or the 03 (if there is such thing). Even if that was the case, what are the chances that they use a different interface? Very unlikely. Controllers are always designed to work for the panel, not the other way around.
Well, no good news.. I am looking everywhere trying to find a service manual for my display. I've called people who specialize in service manuals, and they dont have it. Ive tried people on ebay who sell service manuals.., no reply. So until I get a service manual, or some sort of info on the specs of the power supply for a px-42m5 or px-42v5 or some other model or brand that used this panel I am SOL... so, ANY help is GREATLY appreciated.
these people have plenty manuals. i got my projector service manual from them for $10.00. Check them out. Send them an email asking if they have plasma panel service manuals.

Has Digitalview been any help at all? Have you asked them what information they have on the NP4203MF02 since that could very well be your panel?
any progress on with the plasma panel? the guy selling them on ebay sent me an email asking if i was still interested in one. i guess he was willing to make some kind of deal.

Broken 42 inch NEC plasma screen. px-42m5a
Hey everyone,
Im new to this forum and just started my diy projector but thats not why im posting. I just happened to come accross this listing on ebay that i though might be of use. It looks to be the model that the replacment panel was made for so you might want to take a look and snach it up before someone else does.
Good luck

Frustrated yet? lol
Hope Im not to late. Not even sure how I found this.
Anyway,
NEC 4203 is NOT an NEC model # for Plasma's. 4203 is the package name which is used in NEC model numbers 4200, 4205 and the 4210.
If Im not misaken the 4210 is alos the px42m5a and the 4205 and 4200 have their own #s as well.
Check on NEC discontinued produts and youll see.
The 4203 # your are seeing are on the left and right driver boards of the dispaly and also on the video feed boards that attach the ribbon cables that lead to the glass.
THe dispaly should have also come with a board in the middle.
This is only PART of whats needed to make this work. I have a 4210 and an MP3.
By the way, the guy in Baltimore which has the dispalys are manuacturer defects.
I had purchased 5 of them from him, 1 of them worked good (used it in a 4210 for a replacement) and the other display has a thin green line. (which is tolerable).
The others and you will see them on ebay, have a chip that burns out that feeds part of the segment in the screen. These are USELESS.
The chip cannot be replaced becasue its over with epoxy cement and its located on the ribbon cable that feeds the glass.
Check your display.
Take apart the 2 long silver brakcets. I beleive there are 10 screws in each.
take out each ribbon cable from the socket. Each ribbon cable lights up 3 sections of the screen.
Hence the reason why there are 3 chips. Look at them closely, if you see a hole in ANY of them, you cannot use that part of the screen, which is usless.
Youll alos notice on ebay that you will see many NECs with a black portion on the screen not lighitng up. Thats the issue with them.

P.S. NEC customer support is HORRIBLE

You guys care, you really do 🙂 ATTN Chipdoo
Well, I still have 2 of these PDP modules. I finally figured out that the px-42m5a and the plasmasync 4210 are the same thing, but I didn't know that the 4200 and 4205 would work as well. I have seen a few of these cracked 4210s, or ones with black squares go on ebay for like $600 plus 200 shipping and that is absolutely ridiculous when you can get one that works fine for about $14-1500.
Chipdoo:
You seem to know more about these than anyone. What would you do with these things? Will only the 4200, 4205, and 4210 models work with these PDPs, or can I buy a later model and use the middle board from it?(mp1,mp2,mp3,etc)
As long as my PDPs work ok, It seems that I could buy a cracked display and use the middle board from it or buy one that has black squares and replace the whole pdp, but please correct me if I am wrong.
It seems impossible to find solid info about these things anywhere on the web.
Thanks for the help, everyone in the thread.

What a fast reply!!! loll
Hello GoldMoth,
Good Luck finding anything on the web about plasma's. Its virtually impossible to find anything about them, simply becuase nobody really fixes them and they cost too much to fix.
Not only that, NEC will NOT cater to us non-authorized people and supply us with schematics.
Ive been on the phone with them on and off, but they simply wont help. If someone were able to fix this part that burns out, they would make a fortune!!!
I URGE you to please check your PDP's BEFORE you attmpt to get a hold of everything esle.
Last thing you need is putting every thing together, and it still doenst work.
You are correct, if your PDP's are fine, you can buy a 4200 series Plasma and pop it in. Ive been told however, that there may be more that one design for these Plasma's.
I would try to stick with the 4210 as it has more inputs than the others and it still lacks inputs.
It only has an input for HD, and S-video. Oh yea, also an RGB.
Also, your still taking a chance on buying a cracked screen unit. Think about it.......... The screen is a pretty solid piece of glass. If something broke that, it would have to be a nice impact, so OTHER items may be damaged as well.
Thats the situation im in right now. I just picked up a 42MP3 with a cracked screen on Monday.
I put in a 4203 screen from the guy from Baltimore in the MP3. Everytihng is together, but guess what, it shuts right down once I power it up.
I have a feeling that there may be a crack in one of the boards or something. I kind of narrowed it down to the right and left driver boards attached on the screen, but guess what, NEC doesnt sell these items nor the middle board seperatly from the PDP. (Talk about money making!!).
After you read this, your probably thinking that you can use a cracked MP1, MP2 or MP3 for your PDP.
The answer is yes, but it requires more VERY PATIENT work. All the electronics in the MP series are differnet than the 4200s. BUT, what you can do is remove the actual GLASS from the aluminum backing that holds the boards.
THIS IS A VERY FRAGILE OPERATION!! lol THe glass is thin, but it is pretty strong.
My 4210 right now is operating with a glass that came from a MP2 PDP.
The MP3 that I just got, I used the glass from the 4203 package. I just had to simply cut the 3 ground ribbons a little smaller to fit the connector.
If I knew how to post pictures here, I would and I would show you the MP3 and I would also show you the burnt out chip that Im talking about so you know what to look for.
-Chip
P.S. These screens that you see on EBAY with the black sections that arent lit HAVE BEEN worked on.
When the chip burns, it causes a dead short and the Plasma WONT boot up at all cuase its in protection mode.
So what they have to do is open the unit up, find the ribbon cable that has the burn in it and simply unplug it.
This removes the dead short from the screen and it powers back up again, though with a black portion not lighitng up.
The black section you see CAN be made thinner but cutting out the power input to the chip and then plugging the ribbon back in. The black section will be MUCH smaller now becuase each ribbon lights up 3 sections of the screen.
The screen I through in the MP3 has a burned chip, but its the very FIRST one. So I isolated it from the other 2 good ones and hopefully I could get everythign to work.
When it does work, I will have a black section at the top left corner which goes all the way down to the middle of the screen. I consider this tolerable since its not in the middle of the picture at all.

Ribbon cable problem, Chipdoo
I checked my PDPs last night in a frenzy, hoping not to find what I did. Both of mine have burned chips in one of the ribbon cables. So, I left the house feeling a little depressed, but I started thinking about ways to fix these burned chips. I was thinking that it might be possible to cut the ribbon cable between the chips and the glass and attach 3 working chips by splicing the ribbon cable. I assume that these chips are the same, and I would gladly cut one section from my other PDP to make this one work. Hopefully we could find a connector that could make this easy but if not I could do some careful soldering, either way its worth it.
let me know what you think, if it does work we could get together and share working ribbons and chips.

Bummer! :-/
Sorry to hear that. That stinks. I had purchased 5 of them from the same guy.
1 worked good (has minor screen burn) which I hooked my friend up with. And another had no burned chips, but it has a very thin green line that shoots up from the bottom to the center of the screen. This is my currnet 4210. The green line comes and goes.
The other 3 have all burns in the chips. Which Bites!
If you could find a way to fix this, you can make lots and lots of $$$. According to NEC, the only way to fix this is by opening the glass and replacing the ribbon. But that requires sucking the gas out of the glass and then reasealing and filling the glass again. Thats WAY out fo the question. lol
If you have experience with Microscopic soldering, then it may just work by using another ribbon. This is real tedious work though.
I have plenty of these ribbon cables. If you dont want to ruin yours, let me know and Ill mail you some.
I would be impressed if someone were to solder a new cable together. Though I consider it highly unlikely. (not to bring you down)
I was also playing with the idea of dumping Masonory Acid on one of the epoxy that covers the chip to see what it is under there. But I doubt that would work as well.
On top of that, stripping the ribbon cable to get to the copper lines is very difficult as well, since its very fragile.
The other thing I thought of was simply cutting the ribbon perfectly straight and dipping it into a solder bath. The solder should stick to only the copper and then quickly somehow join another ribbon to it.
I also had contacted AMP (Amphenol). I gave them a sample to see if the can come up with a "crimp" type connecter that joins the two together then simply squeeze the connector and it would pierce the copper lines together. I have not heard back from them nor do I think I will. 😱
The real main problem is, there are so many lines in that ribbon that need to be soldered and they are sooooo tiny........

Thanks for the auction info chipdoo. I talked to the guy on yahoo and he said he would take $300 for the parts if I picked them up., so that is one option, but I think I might wait until the 4210 ends on ebay. Either way I do think I am going to try the ribbon cable fix. Do you know if a early model 60" or 50" nec would use the same ribbon cables as out 42"s? if so we could fix those the same way and have some pretty sweet displays since I have seen several of those on ebay with the same black square problem. Either way I would like to try this ribbon cable fix. How much would you want for a couple of non burned cable ends? just let me know. Thanks
