How do I get rid of "Line" on my 14" TV with built in VCR?

I'd bet on the panel but you can try replacing the t-con and see if that gets rid of it

Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

You must have a show that has an anti-copy signal imbedded into the show causing it to not be recorded. This is due to DRM rules on copy right materials.

Connect one end of the VIDEO
(yellow) CABLE to the AV1 in VIDEO
jack on the back of the TV. Then connect
one end the AUDIO (red and
white) CABLES to the AV1 in AUDIO
L and R(left and right) jacks on the rear
of the TV. Connect the other end of the cables to the appropriate color on the DVD player (yellow to yellow etc.)

Press the CH + or – buttons on the
remote to scroll the channels until AV1
appears in the upper left corner of the
TV screen.
Slide the TV/VCR/ACC switch to
the VCR position.
Insert DVD into player and press PLAY.
