NEED TO REPLACE THE BOARD OF CONVERGENCE

you would need the service manual the adjust the vertical size through the service menu

ptc or decosing coil is bed or notworking proper so u have replace it

need replace the capacitors at side of the ic vertical marked on the , init to the big first.

Convergence amps are failing which is very common. Several hundred dollars for a repair.

Your vertical height needs to be adjusted or you have a capacitor that needs to be changed 100uf 35v, 1uf 50v.

Go to the picture control menu and turn the color to minumum so that you are watching a black & white picture. Do this to determine if the color offset affects the overall screen or just the lower corner. If the center is off, go to the convergence adjustment menu and align the red and blue onto the green as described in the owners manual. Some models also allow you to align the outer edges as well. If the bottom is still bad you may have a problem in the convergence circuit. If the outlines are not seriously bowed or distorted a minor convergence toutchup by a qualified technician should correct the problem, otherwise parts are involved and the repair is considered major.

Usually when the vertical starts shrinking slowly, it is due to capicators getting out of tolerance in the vertical output section of the chassis. If it can be adjusted out through a service menu, you'll probably need a tech with the right equipment to perform it.

Hope you have fixed this problem by now, if that tv is unserviced, I mean if nobody has ever opened it, it could be a problem with the positioning of your tv, just tilt the tv in different positions and find out the position in which it will show the right fit. If it is serviced, especially yoke is changed, this is rare, it could be because the position of yoke is not aligned properly.
