4121941220Hello, I have a NEC Multisync CRT that I am using with my AT, and along the edges the picture is warped. On the top and sides it is warped in, and on the bottom, it is warped out. Please help, I like this CRT and I would like to fix it. I heard it might be the degaussing circuit not working properly.

Thanks, IlikeTech

Welcome to these forums.

Just so that people can be sure about what you are describing, I think that it would good for you to attach a photo of the screen.

It might just need adjustment. Check if there are controls for pincushion and trapezoid. If it's a newer monitor they will be in the OSD.

Iíll see if I can find those controls. I just attached some photos. The monitor is CGA/EGA/VGA Plus BNC, and it was released in 1988, so no OSD.

I managed to mostly fix it. I think it may have bad caps, but I found the pincushion control and it looks much better!
