My cousin was like wtf when he seen that it had two flybacks(I told him that how the set is so bright but he hasn't seen it running yet so he is in for a surprise)
I didn't think that two flybacks could be used like this but I guess I was wrong should I have to worry about the cap on these between them and the tubes?
Every posting I see about this set says that the high voltage power section rarely fails just the caps in the rest of the set as it ages(three boards away from finished which I will have done by next weekend if the spare boards arrive so I can do the eliminate process to find out the culprit board causing the video and grids to not show(which will be getting repaired)

Two HV transformers is nothing to do with its level of brightness. It simply means that is was a more economical option for NEC to use two in parrallel than it was for them to create a larger one.

I was joking with him at the time but he knows some about crt tech but never seen a setup like this (he did like me when I was younger and worked on mostly projection tvs)
The flybacks look about the size of the one in my samsung tv (which has a pretty good picture because I seen it when it was new)
I can't wait to get it running though so I can enjoy it instead of working on it(but I am not going to rush my work to get it done sooner and make a mistake)
Just wish I had more free time(been working on a lot of computers lately and I hope I can get them done early so I have a few days of free time to finish the pg up so I can get it set up right)
I have been thinking of setting up a second screen to use with my Ecp (yes I have enough room to use both in separate set ups)not sure yet as it will cost to get the equpment to use with it (and I don't feel like spending the money yet to do it)
Case my Ecp has a video in on it and I thought of using it for my older games because I don't have a line doubler for the rgb(good idea or bad idea?)

I at least get a few days to enjoy my Ecp without my cousins bugging me wanting to watch movies or play games on it(hopefully they don't want to but me when I get the nec set up but most likely they will)
I know I will enjoy it for sure(might do the tube swap and replace the high voltage power supply in my Ecp while I am at it and get both done)

You can run 15.7kHz into the RGB on almost every set except the Cine 9, 909, 919, 912, and RUNCO DTV 1200. You dont need to use composite video, just connect to RGB.

..Or just plug your composite cable to the G BNC on RGB and ready for a great black and green picture

I would still need a line doubler mate(if I connected directly to the set)
I only have a hdmi transcoder box right now(hence why I am using my DVD/VCR) but the DVD/VCR I have can output 480p/I also (which I think looks better anyway for VHS tapes anyway along with older games)
I have a HDfury coming(with the tubes and boards) so I can use the sets to they're fullest(not only at 720p)
I don't like the video in on my ecp(it makes me think something is broke) I wonder if my nec will be the same way(most likely it will)why did they even include a video(composite) input on these projectors if it gives such a crappy quality picture?
I hope I ain't jumping the gun and think the nec will be the same way with the video in as my ecp(which I don't like the multi decoder input card and have only used twice since I got the set compared to the rgb which I use all of the time)

I tried that on my Ecp with a RCA to bnc adaptor (no picture)
Yes it was getting a signal

Youre not listening.
You DONT need a line doubler. Why would you? Connect the RGB of the console straight to the RGB on the projector. Sync connects to the H Sync. I know it works cause ive done it on multiple machines.

I get what you mean but here in the us game consoles with rgb connections are non exesintent as they are NTSC not pal
There was only one game console that had rgb capability and it was the original Xbox the others at the most would be able to have component video(and that's with a different(expensive)cable then what came with the system)
But the latest systems(Nintendo wii u, ps3/4 and Xbox 1) have only hdmi(which is the only connection on them so but I am getting a Nintendo wii u soon so I will see what connections it has)
Anyway I am getting the parts today so I will update when I have them

Update I swapped out the gain board and got a picture but its only on the red tube
I am going to check the connections between the boards to see if something is loose
I feel so close yet so far away from getting it up and running

Update no its back to the way it was with no video or grids
I was going to try the other video output board but one of the connectors is damaged
So I am back to square one(and really pissed also)just when I think I am going to get it working it doesn't ARRRGG

How many times will i need to repeat this???
RGB is neither NTSC or PAL, so it make zero difference. The first US console that did NOT output RGB was the 3DO followed bt the N64, every single other one did including the PS2, and with the exception of the 2600 and NES, which arent able to without major work. All the others put out RGB from their multi out socket.
If you knew what i mean, we wouldnt be going around in circles with you suggesting i dont know what im talking about.
Time to do some research.

nintendo put out very little info on the multi out socket for here in the us on theyre systems(same for sony)
only thing now the hard part would be getting the rob cable(most likely would be next to impossible)
i know there is no way the nes can rgb for sure(no multi out)and i ain't ripping apart my only working console to do it
the n64 does have a multi output like the snes and from what i have heard nintendo didn't make any change to it(there has been rumors of the nintendo wii having rgb output but it hasn't been confirmed yet though it may not be since the wii u system is out)
i wonder if the ps3 can do rgb as the multi out on it is the same as the one on the ps/ps2(may get to hacking a cable someday)
you should have mentioned the multi out port before(almost all of my consoles have one save for the nes)
but where i mentioned using my dvd/vcr to do the scaling making the picture soft it does that on dvds and vhs tapes also but i don't mind it softening the edginess of the older systems graphics but it does it more then i like(my ps3 has a hdmi connection separate and bypasses the dvd/vcr to my av receiver and is sharp)
anyway i got the boards from curt only to find the box had something sat on it(plainly obvious as the top was a bit caved)and the out put board was on top of the stack and took a small blow but the damage is unrepairible(it had bent the output plug to the red tube)i tried it anyway same thing as before
after swapping the output board back i swapped the gain board and got video on the red and blue tubes so i thought i would wait before i did anything again only to comeback later and power up the set to find it like it was before the swap
so here i am with a spare for almost every board in the set(minus the s-video/video board which i do need to replace/repair it works but the picture is kinda scrambled though not sure yet if it is the cause or not) and the output board(the red tube video output plug fell off from the blow it took in the box  needless to say i was not happy  as i can't enjoy the projector because of this(curse the usps person(stupid nut) who sat something on the box and it clearly labeled fragile)
oh well if push come to shove i will box up my original video output board and send it to curt and have him repair it as i know it ain't my gain board(tried both same results)i will wrap the board in bubble wrap like you would use to wrap a projector in as i have plenty if i have to

Im not going any further into it other than to say the N64 and SNES multi outs are not the same, but youd do good to search online for each console and RGB output to learn the facts on each one. I have used a US SNES with RGB, along with many others. Ive also done lots of mods to lots of consoles, ive tested RGB on and owned almost every console, and never line doubled a single one.
The WiiU has the same outputs as the Wii but adds HDMI. The original Wii put out composite, s-video and component, one model had the component removed and RGB was added.
Getting RGB cables for any of them is very easy, search on Ebay. Almost every console had a SCART cable available for them and that is RGB. Simply cut the cables and join them to BNC plugs, use and LM1881 for sync on the machines that used composite video for their sync. Its so easy its almost criminal.
Show pics of the damage to the board.

I did some research and it looks like the only console I have that has rgb is my snes(the insides of the 64 are different and doesn't support rgb but the pinout is the same on both which is odd but oh well I may get me one of those cables just for the snes(I found a site that shows the pinouts of the Nintendo systems just have to find it again)
I have seen displays with the scart plug before(rare though here in the states)but never the cables but I haven't looked online Yet(been busy back of this)
I emailed curt about the board and am awaiting his reply back
He also sent the high voltage power supply for my ecp(just have to get the time to install it)

Use a SCART to RGB-HV breakout board if you dont want to mod the cables, all it does is reroutes the wires and splits the sync. Only the French N64 has RGB without modding it. NES needs an extra chip from the arcade version of the NES.

Ok I finally got picture and grids from the red and blue tubes so does anyone want to recap my gain board for me(and possiblely my video/s video decoder board)?
