Go into the service menu using the remote (hit the sleep timer, then video status and display at the same time), go into the status menu #2, then power off the tv. This will reset the HDMI port. If your sitll experiencing the issue, probably a dead board.

Most new HDMI DVD players use High-bandwidth Digital Content Protection (HDCP)on the HDMI output.If you try to play this on an older TV that is not compliant with these new standards it will not work.This standard came out late in 2004 that is why your older player still works. There is also a service bulletin from JVC about upgrading the software on your TV for HDMI compatiblity issues.If you want a pdf file of the bulletin I can send it to you.

If the TV works ok using the component,composite and tuner inputs otherwise then the HDMI module is bad.

Hey guys, had the same problem. Found this solution on the web. Worked for me.

JVC HDMI Port Fix

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. Reconnect the power cord, turn the TV on, and the HDMI port is reenabled.


Here’s how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.

This should work.

I had the same problem with my JVC projection tv. It would flash green, then go to regular picture then back to green flashes. Not sure if this is the solution you were looking for, but I was able to get a good crisp picture using composite cables instead of the HDMI cable.
