If you are using a DTV coverter box, you may have changed the aspect ratio with your remote control. look for a button marked "aspect" or "picture size" use that to change size.
If you have a cable box, you may have a similar button.
Or you may find a picture size adjustment on your TV remote.
If you do not have "aspect" button on your remote try going to set up menu and look for picture size.
Older TVs used to have a vertical size adjustment at the back. look in the manual.
If none of the above, you have a biiger problem with the TV internal parts needing attention
yes let me know if you still need help on this one it is in factory defalt, i will look up service manual and let you know the codes to make it a regualr tv again, they have it set to display setting.
sounds like the typical power supply or sweep problem in the zenith chassis. depending on how old this set is will determin if its even worth trouble shooting or taking it in to be looked at by a pro. If your not experienced with tv repair i would call a repair shop or take it in as tv sets have high voltage stored in them even after they have been unplugged for a while. If youve tinkered with tvs in the past or know someone who does zenith tvs are made for a complete chassis exchange. you can Call PTS Corp at 1 800 844 7872 and see how much an exchanged referbished chassis would cost and go from there. Good Luck
