Hi all can any one help us my JVC HD56rf7 Rear Pro HDMI Ports stop working
and i read that they need to be reset in the service menu
done a search of the forum and found some codes but none work for my set
Can any one Help us

Never heard of that model? I know the problem of which you speak, but dont know the info off the top of my head. A simple google came up with this: http://forum.ecoustics.com/bbs/messages/2/172208.html

Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord and wait for 10 seconds. Reconnect the power cord, turn the TV on, and the HDMI port is reenabled.

Thanks Guys for the info
