≥Go to Video in the SETUP menus, and change "TV Aspect" to suit your television.
≥Use the television to change the aspect to the correct one.
If your television cannot change the aspect when input is progressive,
try changing 4:3 Aspect with the on-screen menu icons.
≥Ensure that the unit is connected directly to the television, and is not connected through an

antenna, change to an outdoor antenna.
≥The television antenna wire is too close to the unit. Separate the antenna wire of the
television from the unit.
≥Some distortion is normal during SEARCH.
≥Press [PROGRESSIVE] to turn off progressive output. This problem is caused by the
editing method or material used on DVD-Video, but should be corrected if you use interlace
output.
≥Check the settings in the On-Screen Menu Icons' Picture Menu.
≥Change the zoom ratio to "k1.00".
≥With the on-screen icon menus, change "Subtitle Position" to "0" or change "4:3 Aspect" to
"Normal".

≥You can damage the unit if you play dirty or damaged tapes and this can cause the blue
back to appear. Consult your dealer.
≥Adjust the vertical hold.
