Having a hard time on the google machine finding anything but an old schematic for this model. No manuals that I can find or specs. Does anyone have or know anything about the Neotech NT-600DX series? Resolution capability? Thanks!
 
I was trying it on Paperboy and the OSD just read OVER RANGE, I think I read that I'll have to hook it up to a computer to access the HUD and change some settings, it wouldn't let me access the menu/HUD while it read over range. Haven't had time to circle back to it yet. Thanks for the link
 
Finally spending some time on this tri-sync again and not having the results I'm hoping for...

I can get the monitor to sync to signals at 31kHz, but if I send 15kHz or 24kHz the screen will only display 'OVER RANGE'. I have searched the interweb including KLOV and I've stared at the chassis, neck board and yoke but I have yet to find a dip switch or jumper that will change my results when sending 15/24kHz to the monitor.

I'm using Craftymech's TPG and my test bench to send signals (as well as my laptop).

When passed through a GBS8200 I get a picture but the monitor says it is running at 31kHz.

When passed through a std cga to vga 'pass through' I get the 'OVER RANGE'

The cga to vga pass through board seems to ring out fine, so I do not believe that is the issue. It just seems like I am missing something to physically adjust the sync rate of the monitor. Hoping to put this in my Paperboy with nasty APB screen burn at some point. Any help is greatly appreciated!!
 
that's good to know, but the question is, shouldn't this monitor be able to accept a med res signal and display it without a converter? I thought that is the point of a tri-sync?

Have you looked at the schematic?

the cs1,cs2.cs3 lead to different scan mosfets, test point indicates a wide bandwidth.

The different versions may have switch to svga only.

depending on the last few numbers of the model.

But not according to the schematic I'm looking at!

any chance of getting a aerial photo where all parts can be seen in the photo

if it has the these parts around q407,q409,q405 then its tri res.
 




I can fumble around schematics but it's not what I do regularly. Not the best pictures so let me know if you need more, just realized I didn't get the neckboard so I'll add that in the next post. Thanks for the help
 
It doesn't look like the same chassis as the schematic.

and You don't have the parts I mention in the circuit.

the different version have a different bandwidth of frequency's it cover's.

I would say this chassis is VGA and Up only,

It should only have a vga cable only? Right? or just a d-sub female on the board

but the converter board should be able to upscale the med to vga?
 
It does only have a vga cable as signal into it, so far I have only run std res signals through the converter board and it upscales them to 31kHz, I assume it will do the same with med res but at some point I will test it with the TPG to be certain.

So, long term... I'll have to take the Paperboy video output and run it through a converter if I want to use this monitor, correct?
 
Yes, that's correct!

I think theres a NT-700xxxx also different version of that

and tubes. Before they stopped making crt base chassis.

I seen a few problems with the high res models already.



Just need the full model number to define the chassis.

I had the schematic a few years ago.

But got lost, I manage to get from the china guy on Tech Support

before he disappeared.
 
Well it wasn't the outcome I had hoped for but I appreciate the help! With any luck I'll find a med res tube at some point but at least I have this monitor as a fall back in the meantime.

Thanks again!
