Nanao MS8 slow sync?

sterlingrush on here is the master at the nanao i would contact him and he does fix them i am sure also.
 
Quick view of the video, looks like a Nanao MS8-26A chassis, clear pics of the chassis could help identify it for sure. As for what it's doing, I can honestly say I have never seen that before.

Need more information. Is this how the chassis arrived to you for repair? How do you have the monitor wired up(be specific)? Is it plugged into the cab it's used for? Is it on your test bench, and possibly not wired right? What exactly have you done with the monitor? Anytime I read "I fiddled with xxxxx" scares me, because if you're not sure which adjustments you're turning, you can destroy the chassis and/or tube. Is the monitor set for std or med res signal? What are you attempting to use for testing, std or med res?

Detailed description can get you better help. The way it's clipping like that, is not good, something's being over driven or fed wrong.
 
Thank you very much for the answers, I am away from home so I couldn't answer sooner.
I can surely post clear pictures and post relevant information, but later.

BUT I tried to connect the arcade which is originally for this monitor - SCI from Taito:
http://www.arcade-museum.com/game_detail.php?game_id=9700
I used a color TV with RGB capable SCART and this connection:
R.....pin 15
G.....pin 11
B......pin 7
sync.....pin 20
ground.....17 (or 18)
5V.....pin 16 (in series with 120-180ohm resistor).

But the picture is out of sync, I can see the arcade board is working but the picture is garbled.
Do I need to invert the sync or is it completely impossible to connect it this way?

On your description above, what is the 5v running to? What is its purpose? Unusual to see that listed with RGB, sync, and ground. Is that connected somewhere it shouldn't be?
 
If you have, or can get the chassis out, take clear pics of it, with some close up of any area with any connectors. Post the pics, and I can help ensure you have it setup to run std res.
 
Ok so I succesfully managed to connect my S.C.I. game from Taito to an old TV but I also succesfully resolved the issue with the Nanao monitor!
It was a simple problem - the trimmer on the high voltage transformator responsible for brightness was set too high. Nothing else :facepalm:
I have connected my NeoGeo jamma board to this monitor, and I got a nice colorful picture. But the image is rolling from left toright and vice versa when I turn the trimmers responsible for the horizontal placement (H-HOLD, H-PHASE and also onboard trimmers H-SUB1 and H-SUB2). Vertical is OK. I cannot find the right spot to stop the picture from rolling. It's simply impossibe. Are the capacitors responsible?

You need to reflow large resistors and blow off the board.

and lift the transistor, above the H-Hold control???

it should be standing up, and may be killing something because its in the

wrong position, that's a heatsink laying on other parts.


watch out you don't break a transistor leg

when you straighten it up?

after you unplug the monitor.

You do need to replace the caps.

then adjust the image.
