I just sold a TV (Panasonic 36" flat screen HDTV set) to someone that was working perfectly while at my home. The individual who bought TV from me did see the unit functioning in my home with no issues using an HDTV tuner. Upon the individual getting the set home and hooking it up the picture size fluctuates from getting smaller to slightly larger. This happens even when the TV is not hooked up to any input source and just the menu is displayed. The menu gets larger and then smaller. I have not seen this myself but I think I am accurately describing what the individual told me.
Does anyone have any thoughts?
Thanks, Mike
