Videosphere front cover split open, any advice?

H. hold = horizontal hold if set wrong will get diagonal lines.

V hold = vertical hold if set wrong picture will "roll"

height = vertical height or size adjusts for top to bottom pix size.

AGC = automatic gain control if set wrong may cause snow,
washed out pix, tearing, audio buzz.

The hold controls are usually customer controls. They should move
& protrude out the back. It may be frozen up from age.

If you ever adjust the screwdrive controls such as height use
an insulated screwdriver. Also they break easily so be sure
to go easy on them. I have broke more than a few !

As far as everything goes start with an old book on how to fix TV's.
Learn the B&W TV block diagram, what each stage does & what
happens if not working right. Also get a book on very basic
electronics or better yet a course with labs.

Your welcome.

For an electronic book " Electronics 1-7" was a good
& commonly used book in schools. DO NOT confuse it
with "Electricity 1-7".
Nothing comes to mind for a TV book, there were tons of them.
Start with your library. Also look on e-bay, they cant be much $$.

You can learn a ton on this forum, I fixed TV's near 40 yrs & I
learn something new every day. And dont be afraid of asking
questions, we all knew nothing once.
