1/4 of the screen is cut off when the set is turned on
When the TV is first turned on, approximately a 1/4 of the picture is missing from the bottom of the screen. As it warms up, the picture starts creeping down to the bottom of the screen, but anything pictured on the screen looks as if they are midgets or there legs are very short.

Re: 1/4 of the screen is cut off when the set is turned...
You have a bad vertical IC or leaky capacitors in the vertical circuit.
The capacitors are usually red colored and are 1 uf at 50volt capacitors and are readily available at radio shack. If you have some skill with a soldering iron you can probably fix it. Just make sure you unplug it before working on it and that you never work on it while it is plugged in

1. A button on your remote that says either: ARC, Ratio, 16:9, 4:3.... Some remotes have a picture of a square with arrows pointing out towards each corner..... I'm unfamiliar with this set, but it sounds like a widescreen, so give it a go
Your screen somehow got switched to theatre/cinema mode. There is a setting on the remote that attributes to aspect ratio. Sometimes it is called "ASPECT". Look for it, and press it until your original screen aspect shows.
Hello This is an indication that your vertical output stage is beginning to malfunction. It could be the vertical output IC or the vertical coupling capacitor. I would suggest using the schematic and an oscilloscope to determine if the signal is correct. You may have to replace the IC or the capacitor.
When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.
if your tv has a warranty take it back to where you you bought it.or check if your remote has the zoom feature,if it does zoom it back.or else you will have to call the repair man to program it for you.
No my freind, im afraid that you have bad waveshaper capacitors in the vertical sweep circuit in your TV set. This is not an adjustment. you should have a pro assist you with the repair of this set as it is dangerous because of the high voltage inside these sets.
