MONTGOMERY Ward 8" Solid State TV portable turns on with sound-read description

Description

Vintage SHARP 8.5" CRT B&W TV 1970s Retro Portable Solid State Television NICE!!. Condition is "Used".
I am not sure how to test the picture but the tube is working and all the knobs are functional. Turns off with that white squigly line that resolves into a center dot before disappearing, that I remember from childhood. Sounds appears to be working well  but screen is a little off center. Not sure how to adjust it. There are knobs on the back that may help. I am hoping someone that is familar with these units will help this little girl out. Screen is 8 1/2 by 6 1/2", case approx 10 by 9 by 9". Has a handle and antenna is in very good condition. The unit itself is dusty and has a model number scratched into it in multiple places. This unit is AS-IS for parts because I am unsure how to test more thouroughly. It may be fully working but I am unable to test.
