GE 10" "portacolor III" AB chassis TV

[radiotvnut]

Here's the little '83 10" GE color TV that's unofficially known as the "porta-color III" and uses the "AB" chassis. This is the set that I got with the RCA CTC17 console and was dead when I first tried it. Today, it came to life when I plugged it in; but, the yoke wedges are gone and it will need some minor purity and convergence adjustments. One strange fault that I'm seeing is a big white band on the left-hand side of the screen. It's mainly noticeable on a blank screen; but, can sometimes be noticed on some active scenes. I jumped the electrolytic cap that's in the B+ line to the video output stages; but, it made no difference. I think this is the chassis that has the griplets that need to be fixed and those could very well be why the set was dead when I first tried it. Hopefully, they'll be the cause of the white band on the screen. I think this set first appeared as the AA chassis and is what replaced the tube type "HE" chassis porta-color. I used to see a lot of these later SS GE's and I think they were made until GE got out of the TV business. I think the earliest versions of this set used the same channel knobs as the later tube porta-color.
