My hdmi port in the back of the tv does not work..i have never used this before and we bought a ps3 when i hook it up all i get is a green screen but i know it is not my ps3 or cable because they both work on different tv can this port be replaced on this tv or do i just have to deal with not having hd capability on it ..thank you

1a) make sure the two slide switches on the top of your remote are set
to TV and VCR (both to the left).

1b) Press SLEEP TIMER and make sure it is set to "0" minutes. (Only on
screen for 2-3 seconds)

2) While "0 minutes" is being displayed on the screen, press DISPLAY and
VIDEO STATUS at the same time. This will pull up a service menu on
the screen.

3) Press the option # 2 (SELF CHECK) on the service menu

4) Turn the TV off and allow the set to run its normal cool down
process.

5) Turn the TV back on and set the TV back to DIGITAL IN mode by
pressing on the INPUT button.
