Is my Centipede cab eating monitors? & WG 4900 problems...

[ifkz]

So, I turned on my restored Centipede cab last night and I'm having monitor issues...again!

A little history:  I rebuilt the Atari power supply and audio regulator with a new cap kit.  The first monitor I put in this was a Hantarex MTC 9000.  It died and not even a cap kit or new flyback could fix it.  This is the second monitor it's had and I'm having trouble with it too!  The one currently in the machine is a WG 4900 that I rebuilt with a cap kit.

Here is what it's doing:  the colors are far off.  I don't know if the guns in the tube are bad, or if it's something else.  I spent all night adjusting it, but to no avail.  The chassis has been rebuilt with a cap kit.

The 4900 has also only been able to display a picture in 90% of the screen.  Remember the older VGA monitors with black borders around the image (before stretching controls were availabe)?  That is what this looks like.

I have another WG 4900 chassis to steal parts from if necessary.  Do ya'll have any ideas?

I hope it's not time for a new monitor, they're expensive!!!

Could be the picture tube is weak and needs to be rejuvenated.

As to the small width, it's common that this chassis may need to have the width range capacitor value changed. See Bob Roberts' width cap page.

I can replace a cap simply enough, but how do I go about rejuvenating the tube?  Take it into a TV repair place?  Do you know how much does this costs?
