The remote should have TV, VCR, AUX and maybe CABLE buttons at the top, one of which will light up when any button is pressed. Since it is a universal remote, the button at top lights up to let you know what mode it is in. If the AUX button lights up when any button is pressed, it means the remote is currently set to the AUX mode. To set it back to TV, simply press the TV button at the top. This puts the remote back in the TV mode and the TV button should now light up when any button is pressed. If that works and you are using a cable box with that set, then make sure the TV is on channel 3 by pressing 3 ENTER.

The problem sounds like a vertical deflection issue form what you describe.
On average they are usually in the simple repair categories. On average they would run in the $50 range if you take it to a reputable repair shop.
There are several possibilities
Bad capacitor (s)
Bad vertical IC
resistor in the power supply to the vertical circuit changing value

the variations of the supply causes that. a verticle stability be checked, specially semiconductors and capacitor changing valuas
IT=CV=Q AND frequincy = f=i/t
so if I AND T CHANGES CAUSING MOVEMENT OF PICTURE
SO I is for time and T for tempareture
