Hi All,
I bought this TV 2nd hand & works well...except it appears to be "zoomed" in. I'm losing data on the edges of the screen. I've tried everything the menu will allow with no luck. Is there a way to restore ALL settings to factory default?.....or to undo the zoom?....Thanks, Butch

Two ways I can think of that could cause your symptom to occur:
1) a component (or components) have either failed or "drifted" in value (finding and replacing the bad part(s) corrects your symptom - NO
adjustment(s) required; if you try instead to compensate by adjusting item(s) in the service menu, you may find yourself regularly revisiting to compensate some more;
2) gremlins (or a human being) "changes" one or more of the adjustments stored in the EEPROM. Both have been known to happen. Readjusting the right items to the correct values would then correct your symptom.

WARNING: Entering the Service Menu and adjusting the wrong item to the wrong value MAY permanently make your set inoperable!
Proceed AT YOUR OWN RISK!
If you try to reset (as if you've replaced IC802) read top of page 3 FIRST!
You may want to write down each item & value BEFORE you change them, or better yet, get one of our opinions FIRST.
