Sony PVM 2730QM Calibreation Issues.

Post by Thamiel »

Hey lads, just picked up this beast today and it's in generally good condition. However i'm having a few issues with the picture, just some geometry niggles and what I believe is a convergence problem on the right side of the tube.

Here's some pics:

Any help getting this fixed up would be great, already taken the back off the monitor and had a tweak with the pots but still not getting it all the way there.

Unlucky with the convergence issues..... this is something you can't adjust via the chassis (that's BVM territory only I'm afraid).

You'll either need to adjust the purity rings on the back of the tube (not recommended unless you really know what you're doing) or by applying stick-on magnet strips to the back of the tube. That convergence issue you have is fairly bad.

Started messing with the purity rings and have gotten things quite a bit better, most of the convergence problem is localised to the middle right of the tube now, I'm thinking some magnet strips might might solve the last niggles. Probably gunna have to remove the metal frame behind the tube though. Not excited about that as just loosening the yoke to mess with the purity rings was fucking nerve wracking haha.

Any particular sort of magnets, or can I just cut strips from a fridge magnet or something?
