1971 Sylvania TV - Need Help with Horizontal Hold

[Username1]

You need to look for a control called Horizontal Hold, most likely it will be in the
front of the tv, maybe inside a secret little door that only you may know....
It may just say Horiz. But I'm gunna stick to it should be in the front.....
Trun that one a little, and the picture should straighten out. Then later
if you need to, you can turn the AGC, it should be in the back....
