In the customer menu page thru it until you come to a page that has an item called convergence. move the cursor down to hightlight this and press enter. The next screen will have an Auto on the top line and a Manual of the second line. Hightlight the auto and press enter. The TV will attempt an automatic convergence alignment. BE WARNED>>>It will either correct it or make it worst. If it gets worst then the TV's convergence circuit has aged and is starting to fail. If it corrected it it's the same aging but not as bad, YET. If there is no change or it got worst then you will need to have the TV serviced preferbly by an authorized JVC service center because they have access to the service literature and buttetins.
