Good morning to all,
My name's Luca and I'm new to NeXT Computer :) I would like to ask for a problem that is driving me crazy.
I have bought a 040 25Mhz Cube on the web, with a monochrome 17" Megapixel Display, it was the first time that I turn on one of these incredible machines, and I think it's really gorgeous.
After a while that I was enjoying it, I saw that the image on the MegaPixel Display N4000A was about 2°-3° counterclockwise rotated.
The Display wasn't placed near magnetic sources.
As I see there are no adjustment buttons on the display, so I was wondering if someone has had the same issue, and if there is any solution.
Some additional information that may helps:
Keyboard and mouse should come from a N8509 part (NeXT Station starting point kit), I'm not so versed, but I think they are non-ADB, and as far as I know they should also work for the Cube.
The connecting cable between Cube and Display comes from the same kit and it's a 1.5m cable with 19pins connectors.
I hope that someone could help me.
Thank you!
I think image skew like that might be caused by a low voltage power supply issue? There are adjustments, but I never found one for rotation (I'm not an expert, obviously).
hi luca
i think there's no other solution than getting inside the display if you want to correct this. but beware, there are high voltages inside CRT displays. don't blame me if you're getting electrocuted :twisted:
maybe the yoke coil got lose during transport?
have a look here ->
http://www.biwa.ne.jp/~shamada/fullmac/yoke_adjustmentEng.htmlhere's what you need to do:
3. Tilt Adjustments
If glue is holding the yoke collar in place, cut through the glue using an art knife.
1. Loosen the yoke clamp screw two or three turns.
2. Switch on the computer.
3. With one hand, grasp the plastic spokes of the yoke collar, and rotate the yoke collar until the top and bottom edges of the picture are parallel with the top and bottom of the bezel. Using a mirror to view the computer screen, make sure the edges of the picture are parallel.
4. Switch off and unplug the computer.
5. Discharge the CRT.
6. Hold the plastic collar in position and carefully tighten the yoke clamp screw so that the collar cannot slip. Do not overtighten the screw.
7. Replace the cover, connect the AC power cord and switch on the computer. Make sure the top and bottom edges of the picture are parallel with the top and bottom of the bezel.

Thank you for your answer!
I'll see if to bring it to a tv repairer to fix it (I don't want to die :)), or to keep it as it is.
At least now I know that is a salvable problem.

Luca
