Anyone know where I can get calibration/repairs for an old Sony CRT? (Probably a long shot)

I've got a couple of old Sony Trinitron WEGA CRTs that I'm trying to hook up to my old game consoles & such. They both need image calibration and I'd rather have someone who knows what they're doing take care of it. (One of them belonged to a family member who is deceased, so I really don't want to risk damaging it.)

Anybody know of a repair shop or even a hobbyist in Houston who might be able to do this?
