Solution

output port on the back of the VCR and the TV. Make any cable you have attached

For best image quality, view HD wide screen programs where possible. If HD
content is not available view "Standard Definition" from a digital source. Standard,
analog TV will always be noticeably inferior to HD because your digital flat panel TV
has video that is many times better than old TV's and so you can see interference
and deficiencies you did not know you had.

technology, however, sometimes some pixels of your LCD HDTV may not display.
Pixel defects within industry specifications are inherent to this type of product and do
not constitute a defective product.
When your LCD HDTV's digital capabilities exceed a digital broadcast signal, the
signal is up-converted (increased) to match your TV's display capabilities. Up-
converting can cause noise or trash.
The TV remembers the volume level from the last time you adjusted it. If the sound
level is higher or lower from another source, then the loudness will change.
