Will definitely try it, I have not played with any setting's on anything or touched any of the pots for it yet.

It's a nice crisp clear still display when it's working it just fades out after a few minutes after it seems to heat up some.

Ropi Jo:

If you turn the lights down in the room you'll clearly see the tube heaters. Watch for the heater going out when the issue occurs.

It ended up being bad solder joints from the manufacture.

Mine all still looked solid shiny and purdy from the cap work I did a decade ago.

I seen at least three points that didn't look good at all so I got those three and then there was about ten more that were questionable if they had a hairline crack so I just hit them all with some heat and added a little fresh solder since I already had it out might as well type thing.

Put it back in and I let it run for 2-3 and was perfect but now the screen was actually too bright where the black was more grey and the white color was too rich so I just barely touched the screen pot on the flyback and turned it down a hair and boom it looks like a brand new screen again.

Thanks for all the help and suggestions, glad it was a free fix and one I could tackle with all of your help again.
