pic 4 of the large board on the right is too big to post but there are no open connectors on it anyway.
Does anyone here think that all I need is a controller card and power supply? or are there other mystery boards that I need?
any info is appreciated..

Hi, found some info on nec digital interfaces, can you get the model number of the processor, should be the big chip and board ID. What does the black connector say on it? Not sure but that could be a dvi interface. If it is you could use a computer to output to it. Probally the cheapest solution.

the white numbers on the bottom say DIGITAL BOARD 942-200219


the black connector says JAE TX3-80P-LT-1 991

the chip on the opposite side from the controller connector says:

XILINX

XCS40XL
PQ240AKP9937
A1098012A
4C

plus, all of the other chips are NEC. with lots of numbere on them.

Actually, I don't have a clue as how a plasma's light source works. If it's like a TFT, then you'll probably need a backlight inverter. But I don't think it works like that.

As far as controlling the thing, that's all taken care of on the controller end. So if you get the SV-1600, there are several "button board" options, as well as the option for an IR reciever so you can use a remote.

Has Digitalview called you back yet?

man, i imagine if he gets it to work then the price on these panels is going to sky rocket:bawling: . might be worth buying one and holding onto it 😕 :scratch:

last auction ended at $204.00. that $199 shipping charge is all thats keeping me from purchasing one right now.

well the sv-1600 needs 12vdc@4Amps so thats not really a problem. But............ the real problem is finding a seperate power supply that will power the display. NEC tech support doesnt even know what a 4203 display is, but they do know what a 4205 is and the power supply for it is $1000. so plan B is to try to use a 350 watt computer power supply. Does anyone here know how to find out the power needed to run something with out having a schematic for it? If I can just find out how to power the display everything is cool.. its a 22pin connector but I do not know the amperage or voltage needed.

plasmas dont have any kind of backlight or anything like that each pixel is a bubble, filled with gas. with 3 subpixels within coated with phosphor.

I was searching a lot last night, and I found no such thing as an NEC 4203 (I did find the 4205). There is a Fujitsu 4203. The thing is covered with NEC ICs, so I'm sure it's an NEC. Are you sure that's the model number? I don't think it would just have those numbers on it. It would look like "PDP-42XX" or something like that.

Interesting. Well since that's the case, I'm pretty sure that the controller will feed it the necessary power. That's how LCDs all work (minus the inverter which is AC power). Is there another open connector on there or something?

Basically, if Digitalview knows how to drive this panel, that means they know what the schematics are and will know what is required to power it- even if it uses a seperate connector for voltage.

someone is selling a broken plasma 40" display on ebay for next to nothing. It had a $149.99 buy it now but for some reason when a bid is placed the buy it now disapears. i've noticed this recently on all auctions. i wonder why. maybe ebay is having problems.

anyways, maybe the power supply can be ripped out of it and used for this panel.

As soon as a bid is placed, eBay pulls the Buy it Now option... You might have seen it before because the bid has to be above the reserve price. So... if there's no reserve, then the Buy it Now disappears right away.. but if there is a reserve.. the bidding has to go past the reserve before Buy it Now disappears.

I really wish that this thing was a common model. like an mp3, PDP-42XX, etc... but I do believe that a 4203 is a real model because digitalview has it on their list of compatible models. It seems really strange that digitalview knows what it is but NEC doesnt. I think whats really going on is that NP4203MF02 is only the part # for the PDP, just the panel. Not the whole unit that you buy in the store. I think that nec may have put this 4203 panel in many models, but at the moment I have no idea..
 
#36
could it be that panel is not for an nec? maybe nec makes it for toshiba or panasonic or pioneer etc.

just because it says nec it doesnt mean that its only for nec. im sure those of you who have opened up lcd panels will see different brand name lcd panels in there even tho the case says "viewsonic" or similar...

I thought it was an NEC Plasma Sync 42.

If Digitalview has it listed as a compatible controller, try it out.

Dude, Goldmoth. I just looked at the diagram. NEC Plasma NP4203MF02. What makes you think that's not it? I'm sure that's it. Keep in mind, these aren't laptops screens. How many 42" NEC Plasmas could there be? How many with "4203" in the model number? And of all the 42" NEC plasmas, what are they chances that they use different data interfaces?
