I got this TV, a Sony TV700U, at a yard sale today. It works but the picture is too short. There are two holes in the back for adjusting this but the screwdriver I used just made the picture bounce around. Any thoughts on how to fix this picture? Google says almost nothing about this TV.
Here's another picture from Flickr.

Try it with a plastic tool. The metal screwdriver changes the resistance and throws of the adjustment. If that doesn't work, then I think that there's not much else you can do. Hope you didn't pay too much for it.

Just $3. I'd love to gut it and put a Mac Mini + LCD in there if it really is broken.

Not to rain on your parade but after June 12 it won't work unless you use a converter box. Which kind of defeats the purpose of a portable.

The picture tube is going... that happened to my 32" Sony TV
The picture is squashed - sometimes the picture will flip upside down tear it apart and put a mini into it... maybe a Dell Mini

It has a cute Mac 128k look to it. Wish there was a way to modernize it but keep the functionality of the controls.

Usually can be replaced, problem is finding a replacement high voltage supply and also finding a repair guy who knows how to do it. The adjuster can sometimes bring the output back to the right range for a while, depends on how far gone the high voltage supply is.

Ah, I got a tiny metal screwdriver in there and got the picture the right size. Now I have to figure out how to connect my analog cable through the VCR tuner and into the antenna jack. It looks like a mono 1/8" plug. Can anyone confirm that this jack is an older analog standard?
