When i turn on my Tv the picture is majorly stretched. When i let it run for a while it almost goes back to normal but it's still stretched top and bottom. It's like watching a DVD on the zoom in mode. There's no menu to adjust the screen height or anything and i was wondering if there was a hidden menu or if it was something inside the tv that had to be fixed. Any input would be appreciated. Thanks

Sounds like something inside needs adjusting. There are some potmeters, usually *inside* on a TV, that can adjust where the image is located on the screen. On some computer minitors these are outside to let you adjust for different resolutions.
Unfortunately, you will probably have to open the TV to adjust this, and you probably shouldn't do this yourself. Why? Because there are components inside that holds thousands of volts and thay might shock you if you touch them. *Even if the TV is disconnected from the mains!* Don't touch anything metal in there with your fingers or with a metal object!
If you do open it and try, look for the small screws that can be turned. They may have a slit for a screwdriver on the end. Adjust only one at a time, and only a little until you find one that changes the property you're after (image height in your case). If the screw changes nothing, try a little more, or turn it back to where it was and try adjusting another one.
A trained TV repairman should be able to fix this pretty quickly.
If none of the adjusting screws helps the problem, it might be caused by a defective component, and you'll have to know quite a bit about electronics to fix it.
And while you're at it; clean out any dust in there (there will probably be a lot!) to help prevent any fires later on.
I've been in electronics more than 20 years and I still use the shake, rattle and roll method of testing. :)
From what you've described you probably have a poor solder joint somewhere on the CRT board or in the vertical deflection.
Turn it off, unplug it and leave it sit awhile. After a few hours you can remove the back and carefully inspect the CRT board. That's the little board you'll find plugged onto your picture tube. Be careful NOT to touch the printed circuits. But with your glasses on look at the solder connections on each of the components. If something looks like it has a tiny crack all the way around the solder connection remove the board and resolder that connection...
if you find nothing there you can remove the main board and do the same in all the area around the IC's that have metal heat sinks attached to them... If you find something that looks suspicious carefully solder it up...
With all that you should find the problem and if not button it up and take it to a repair shop. It isn't too expensive to have some poor solder joints repaired.. In our shop here it would be about a $60 dollar job plus tax.
Hope this helps
It sounds like you have a "pin cushion" problem. There is a "pincushion circuit in your set that causes it to make a "square" picture. Some component in this circuit has failed.
I am assuming that your set is the "picture tube" type--- not LCD or Plasma.
You need to have a tech check it for you.
Hi. When TV has one color only, Unplug CRT Socket. if voltages for cathodes within 10% of each other, Problem is with CRT. check green video amp on crt socket, it may be shorted or leaky, if ok have crt checked for short involving the green cathode.
