In all inputs including digital cable you can see a dark top of a circle across the bottom of the screen with a blue outline of the top circle above it. above that is blue lettering matching whatever the bottom reads (i.e.: TV VIDEO: TO SELECT)

Try unplugging TV while it is on and let sit for 20 minutes. Re-connect and see...
It sounds like your horzontal control is bad. It requires a new circuit board.

Picture only in middle of screen


Sounds like vertical problems on your circuit board. Unless you have some electronics experience you'd better take it in for repair.

The inside of a tube TV contains high voltages even when off and unplugged.

Picture to wide


This trouble symptom picture wide or"blooming", the picture becomes dim even with the brightness control full on,and there is an abnormal enlargement of picture or raster.Usually,the enlargement is uniform,but there may be some defocusing.In some circuits,the brightness control operatesin reverse(rotating the control for an increase in brightness produces a decrease) after reaching a critical point on the control. If the picture wide is not accompanied by insufficient width(a symptom of horizontal output failure) the probable cause is a high volatge circuit ony,particularly the HV rectifier and HV winding.Any circuit problem that reduces but does not completely eliminate the high-voltage output to the picture tube second anode can cause overscan. The most likely defects are leaking high-voltage capacitors,defective high voltge tube rectifiers,leaking high voltage leads,defects in high voltage circuit protective resistance,and shorted turns in high voltage winding of the flyback transformer.

Hope this may help you;

Color is not good around outer edges of picture


When the colors are off around the edges on a regular picture tube TV, it usually means that the degaussing thermistor's solder joints have cracked loose. Another possible cause is that a strong magnet, such as in a stereo speaker, was brought very close to the picture tube and has magnetized the tube. Resoldering the solder joints on the degaussing thermistor and demagnetizing the picture tube should put the color back to normal.

Missing channels


Try going through the auto program feature first and see what happens. Otherwise if the set is new have it replaced.
