Started trying to learn how to set-up a 9PGX last night and it's rather awful. According to the instructions here you should not have the raster Horizontal width, called "amplitude" any closer than 1/4" from the tube edge or the deflection circuitry will run very hot. Problem is the actual projected image is even smaller than the raster, so you wind up with 1/2" on both sides of unused tube. It definitely seems like the previous set-up (wear) was used exactly like this but is it correct?

Also, certain controls like Keystone don't really seem to do anything, is that normal? Biggest problem of all is the remote doesn't work if pointed at the screen, I have to look at the screen and have to remote twisted around backwards pointing at the PJ, is that normal?
Did a search for 9PGX set up and only found one thread talking about someone who was buying one

First, the NECs are very good little sets, feel the power to controll the whole image
Well, you can max up the actual image in the raster with the right porch settings, otherwise it was suggested by someone to pull back the deflection coils therfore maximalising raster width, however the tube neck would very sensitive in that case.
That link, you referred gives a very good setup order.
Try to change batteries in the remote, it should work pointing to the screen, or connect it through cable. As for the keystone issue, probably there is a problem with the wave-board

Makes you love our marquees more doesn't it?

[draganm]

thanks, I'll try some new battery's. I also need to print up about 50 pages from the factory manual it seems. At this point I just want to verify function since it will likely be parted out. Waveform might be bad, CHECK

Crafty Japanese. Did you try the konami code?

NEC PJs are a different breed I will admit that. The only other brand CRT PJ I have ever seen or used would be the Sony 1272Q, and I did get the honor to see Jerry G90 in action with some HD Star Wars material.

I still prefer how an NEC operates as far as controls and functionality. Yes they are pains in the ass sometimes (as I have re-re-re discovered last night) but all in all, they are worth the hassle when the cooperate

And don't you just love the setup remotes? I got so sick of batteries dying in it I just do as you do, and face it towards the machine

[CasetheCorvetteman]

Firstly if youre trying to use any type of rechargable batteries, they are not going to work well, voltage too low for the setup remote. They do tend to chew them up abit, so use very good batteries or youll only get a couple hours out of them before youll be pointing back at the projector again.

NEC machines are not hard or complex to set up at all. If you understand the controls, its a piece of piss to set one up. And they are VERY stable too.

Which keystone menu are you adjusting and getting no result? There are numerous keystone adjustments on an NEC.

Well im glad you liked that one too

I never gave it a second thought til you brought it up...

[wallace123456]

Heck, use a cable from the remote to the front of the pj; at least during set-up. It saved me a boat load of batteries.

The problem with the remote not working unless you point it at the pj, well, that is odd. All my (6 total; only 4 remaining) NEC/RUNCO 6pg xtras worked fine pointing the remote at the screen.

Ken Whitcomb was the best person I met for NEC/RUNCOs. He is a true wizard with the machines.

It's not the worst user interface I've seen. that honor goes to the G70. I'm sure once I learn it will be fine. Printed up 70 pages of user manual last night since the guide above didn't explain some basic yet still mysterious functions. I need to learn the one in my garage since I will be setting one up in a brand new HT at a friends house.
BTW, his a 6PGX and this ones a 9. Any reason why the one in my shop would be a better choice to the point of justifying swapping tubes? 720P max rez in either case

[A Rogers]

[CasetheCorvetteman]

If youre only using 720p why swap to a 9? Probably not much point really, unless he wants the comp and S inputs, and wants point and doesnt want to swap 3 boards... Do we know yet if the keystone is working on this 9 or not?

A Rogers, youre right as far as im concerned, the NEC makes perfect sense and is easy to set it up.


Draganm, what do you need explained??

[draganm]

Of course you can converge without point board. By the look of your first picture your red vertical amplitude is too high, try to decrease, and play also with red vertical linearity, adjust vertical (red) key-stone, and adjust the red upper-keystone, and a bit left-pincushion at the end. (hint: if you see small arrows in certain menus in the direction of the four edges there you can select which area do you want to adjust by pressing CTL+arrow)
You can't blank out the AKB but you can switch it off, hit INFO and set AKB to OFF.

[CasetheCorvetteman]

Personally, i wouldnt have convergence any other way than it is on an NEC, cause it is quite simply the best there is. You can get it flawless with the point board, but you can get it extremely close even without it. You just need to know what youre doing. Once you play with the controls and know what youre doing when you adjust each one, youll wonder how you ever did without such control.

And what's more, with an NEC, when you set the convergence, it STAYS SET. Its not like a Marquee where you need to wait 25 minutes before it lines up with where it shouldve been all along.

[CasetheCorvetteman]

Turn that AKB crap off.

Ok, question number 1, the reason it is like this is cause you havent set things up right yet.

Do the phase first. Then get the green spot on, which is easy.

Do the bow and tilt/skew again with the cross hair. Then touch up the pin and key and the balance settings of each one.

After you did the linearity, you will need to re-center the image on the red and blue, and re-aim the tubes. Then you may need to make some very minor adjustments to some settings again, but this doesnt take long.

You can usually get it pretty much perfect without the point, but it will sometimes time a long time with some things to get the corners perfect, a couple touches of point will fix it.

There is 2 different settings for point convergence, fine and coarse, and to go between the 2 you change the grid type. If you put it on cross hatch coarse, you get more movement from each press, on cross hatch fine, you get about a 3rd of the movement from each press.

Use point and dont let anyone else tell you not to, cause in my experience NEC convergence when set up properly does not drift. Not even a little bit. It would drive me up the wall if it did cause i cant stand anything less than perfect convergence.

I cant see where anyone would have an issue with having SO MUCH control over the geometry as you do with these projectors, even if you had a wrinkle in a drop down screen you could still get the picture 100% spot on with these things. Sure, i can set up my Sony VPH 1001 analog convergence in under 5 minutes, but if its not perfect on the whole screen cause the screen isnt 100% perfectly flat, then im f***ed and there is nothing you can do to fix that.
