greetings all im pretty sure im in the right place to ask for some help on my newly aquired nec 6xtra this is my first crt and im stuck right at the get go im planning on floor mounting this projector and upon initial start up the images are set for a ceilling set up ive done some searching and read the manual and still am stumped on trying to flip this for my configuration can some one please help me on my first hurdle

Chceck inside the lid for the connector changes. There's 12 in total. 6 pairs on the deflection board right under the top cover, three yellow/brown and three blue/red connectors. Pull those out, turn them around and plug them back in. the inside of the lid should show the corect orientation for the convergence plugs that are under the deflection board. The deflection board flips up once you undo 2-4 screws, depending on how many are left.

What are you trying to connect to the projector?

also, this will aid in the setup:

I wrote that for the NEC XG, a model higher thqan the Xtra, but most controls are the same.

hey curt thanx for the kwik reply yes the first thing i did was check the lid but the instuctions were tore half off thats the reason for posting for right now since im a noob on crt and this unit can only use rgbhv ive got a breakout cable for my pc just for testing im not sure yet if ill set up a htpc or invest in a scaler ill wait and see if the unit is in proper order. i pluged the unit in and all tubes fire up but seems lke the lenses or tubes very off set ive done lots of reading and done lots of searching on this site so far ive got a good understanding on getting her up and running im just at the first stage of it so far oh and yes i read your guide front to back maybe once more before i give it a go

hey curt thanx alot got right side up

When you're doing the setup, make sure you do a signal entry first, and run the computer on the resolution you want while doing the setup. These data grade sets all lock to a memory location based on the input resolution. the NEC should lock perfectly to any resolution around 800 X 600 to about 1024 X 768. It won't do 1080p, but with a good Pc, you shoud be good to go. There's lots of computer guys here that can assist with hardware selection if you go that way.

Cheers!

Just an addition. My 6PG xtra locks to 1080p, the picture is not perfect, but watchable, however 1080i (eg. at 96Hz) looks far better.

thanx again for the good info guys now for my next hurdle upon further inspection of the machine i noticed that the output on the blue tube is not as intense as the other 2 can this mean the tube is soon needing to be replaced if so would anyone hear have one i can buy

[macgyver655]

Are your whites, white?

[illpanteraa]

well honestly i havent made it that far in the set up im still in the set up Electronic astig adjustment phase of the guide but you can tell the difference in brightness i had removed the lenses for cleaning i turned on the machine set up the cross hatch pattern and ther was a signifagent differance in brightness so i got worried a bit so i hooked up my pc to it and the screen had a light blue hue on the the srceen im hoping thats because i havent finished the set up

[macgyver655]

[illpanteraa]

well thats good news that takes a little worry off me

[Curt Palme]

Careful about that scan rate. Not that you're going to go over 1080p, but the set is not supposed to lock to that, and you blow your deflection board if you scan too high..

hello again i have another isue with my projector was putting the set up on hold the past few days and decided to start the set up and noticed somthing else with the blue tube it never shuts off i noticed this when i turned on the machine and all the tubes were off but the blue. when i set up the crosshair just to green or red the the blue will still fire any ideas ? i can ta a pic if u need

[Curt Palme]

If you don't have a signal input to the projector, that's quite possible, as the color balance will be all over the map. If it's doing it with a registered input signal, try going into the 'color balance' menu, as that will reset the gains of all the tubes. Chances are the problem will go away.

But otherwise the blue shows the right image, I mean balck levels and white levels are ok with blue? Otherwise it looks like your blue neck board went wrong.

[illpanteraa]

hi guys well i tried to go int the adjust menu and find the r g b gain levels and i dont have one and yes this aso happens a signal added

[illpanteraa]

hey curt i myself not being tech savvy is there a way for me to test to see if theres an issue with the blue tube
