The vertical hold on my tv goes up and down. The picture still shows but its just in the center of the tv but if i hit the side it goes back to a fullscreen.

It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.

Horizontal centering is performed in the service menu. Beware! You can mess up a lot of stuff in this menu.

your vertical hold is out on the tube. new tube is needed. cheaper to get a new flat panel tv.

Check for the cracked solder joints on the IC or dried capacitors on the vertical side

ok
keep tv off.
it will only get wors
if sumon dosent work on it soon
the problem you are having in the vertical section of the tv
hav a repairman resolider all conection on the vertical IC and check the serounding componets for falts.

regards daniel.
PS the repair takes me about 15 min.

You possibly have a cracked solder joint in the vertical circuit, possible the vertical Ic itself. You'll have to remove the board and look carefully at the soldered connection of the vertical circuit and see if any are ring cracked. Some soldering should fix the problem. If you let the problem go too long the heat these cracks generate will eventaully short the vertical Ic..

Your trouble is with the vertical deflection circuitry. You'll need to have it serviced by a professional.

no control over the remote..but impossible not to have vertical hold control in the TV itself. it should have one maybe at the back.

resolder the vertical output IC . bad solder there can make the CRTs blank for protection and you will lose the picture when the vertical drops out.

Vertical lines down the center only means that you have a loose connection on the Yoke. Re solder all the connection on the yoke and where the yoke connection meets the main board.
