I finally decided to upgrade my input to HDMI once my cable company got a new box that had HDMI out. When I hooked up the TV the HDMI input gave me only a black screen then after plugging it in and out a few times gave me a green screen. I know the box and cable work since I hooked up another TV and it worked fine. I called JVC and went through the whole HDMI reset without any luck. They said I need to get this serviced, but I really don't want to pay for this for a TV 3 yrs old, especially since it obviously never worked from the beginning (I just never used the HDMI input until today). How much would this cost me (or is there something I could replace or check myself for less money?)
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.

This works great, but for a JVC model lt-47gz78 to get to the service menu press the MUTE and DISPLAY buttons simultaneously.
My remote does not have these buttons. The remote is RM-C1813H, can anyone help?
this worked like a charm on our HD55G466 - for a $68 blu ray player we can now wirelessly stream Netflix on our 2005 projection TV! Thanks

JVC AV-48P575 HDMI reset procedure:
1. Unplug HDMI cable from tv.
2. Unplug the tv.
3. Remove the rear (low) back cover.
4. Find the 6 pins on the board of the HDMI module and shortcut the pins no.1 and no.2 using a jumper(i use an old hard drive jumper).That's the higher to pins if you can't see the number.
5. Put back the rear cover.
6. Plug the tv.
7. Turn on the tv.
8. Unplug the tv(without tunrning it off).
9. Remove the back cover.
10. Remove the jumper on the pins 1 and 2.
11. Put back the rear cover.
12. Plug the tv and you're done.

On JVC HD-ILA TVs the HDCP is triggered off by light.There is a light sensor behind the rear panel. If the rear panel is removed and the TV is powered on the sensor will lock out the HDCP of the HDMI signal. You all tried to do the reset procedure but you didn't say if the back panel was on or off. If you do the reset procedure with the back off it will just lock out again. Very strong sun light hitting the back of the TV will cause some light to get in thru the vents and trigger a lockout. An NG next to the IP is normal. All of the items listed on the two vertical columns need to say OK. If you reset the HDMI and you are still getting a green screen there is a possibility that the light sensor has failed thinking it is seeing light and causing the HDCP to stay locked out.
IF you get a black screen when you connect a known good HDMI signal this means that there in a compatability problem. A black screen means there is HDMI protocol communications going on but the signal can't be decoded.
It is the same thing if you pick up the phone and dial a number in Moscow, the phone there will ring and a Russian will answer it, So communications have been established but if you can't speak Russian and they can't speak English you don't have a picture.
Many people confuse a green screen and a black screen as being the same thing, They are not.
It would also be good if you give the exact model number since there are several generations of HD-ILA TVs now and the service menus differ a little.

Thanks Dwightvwolf !!!!! This solution should be more accessible. I read somewhere that there was a "fix", but it took me an hour to find this page.
Again, Thank You,

I have the exact same problem. Very frustrating
Same deal... new Blu-Ray player with HDMI cable just giving me a greeen screen. Samsung player, 46" (or so) JVC HD rear projection tv. Returned the cable, same result. Didn't work coming from the PS3 either. Someone please help!!!
I tried "Solution #1" It says "NG9" next to the HDMI. What does that mean. It didn't change anything, it still doesn't work
Same thing here. I have done the reset several times and I still have NG9 next to HDMI, RGB, and TUN. It says NG3 next to IP. How do I fix this problem so it would reset to OK My product is the HD- 52Z585. Thanks
Hello,
I am having the same problem. I have a 52Z575 Dec 2004 Serial 17984527. upon searching the Net, I found out how to reset the HDMI port and did so without taking out the back cover. I am not using any HDMI input. It is still showing green pictures with regular cable tv (Comcast), xbox and dvd. I am not sure if this is relevant but it takes about 15 seconds after powering tv on to get any pictures and Lamp LED blinks slowly for 30 sec then went out. When entering the Service Menu; Self Check, everything is showing as OK, except for the SYNC M:OK S:NG HD:NG. Any ideas what could be the problem? Thanks in advance!
Im having a similar problem. I have Direct TV and Im running the HD box thru an Onkyo Surround Sound System and then to the TV. I was getting picture at one time but obviously it is no loner working. I have tried to run the DTV box directly to the TV and it still didnt work. The Box is under a year old so Its unlikely that its the box. I have tried to run the HDMI from my Playstation 3 thru the TV but Sony said that its possible this TV is unable to read the HDMI from the Playstation 3 anyways. Any suggestions? I've tried the reset, changing HDMI cords.
My HDMI port just stopped working. I used same cables to input in to other port and it works fine. Now I have anly one HDMI input instead of 2. Any ideas why the first port doesn't work?
I was getting the black screen on my jvc av-48p575 and I read your instructions and followed and It worked perfect for only about 6 hours then back to the black screen again?
i tried the jumper fix and sure enough it worked great, but as soon as i changed to a different video input it stopped working again.
any ideas as to what is happening? am i missing somehting?
The model # is 52Z585 and as you said, I do get a black screen but neither my PS3 nor Toshiba HD Player can't be seen. How do I resolve the communication problem?
