I reset my hdmi on my jvc and the menu stills show a NG3 Code, what does this mean?

unplug it let it set hit power button plug back in might work for you

Is there a master reset?
Look in your user manual, or get in touch with a JVC tech.

Good Luck.

Hello
If a power interruption occured to your household power supply, V-Chip has to be resetted. To reset the V-Chip do the following.

Channel guard and V-Chip settings are protected by a four-digit lock code. Your TV comes

preset with a lock code of "0000". You may change the code to any four-digit number you wish.
To change the lock code, follow the steps below.
Press the MENU button
To SET LOCK CODE use UP/DOWN buttons.
To operate (lock icon appeares on pressing =>/ Press ZERO to access the lock code
The first digit will be highlighted
Use =>/<= button to

Press Up/Down button to
To move to the next digit
Continue to follow these directions for all four numbers
Press the OK button to finish (your lock code is now set)
Press the Menu button when finished
OK. Thanks for using Fixya.

Set the remote to "TV" and 'VCR". Press the sleep timer once and "0 Minutes" will show up on the screen. Afterward, press and hold the "Display" and "Video Status" buttons simultaneously and then let go. A menu will show up on the screen, then press "#2" on the key pad. A new menu will show up on the screen, then shut the power off. I was told it could take up to 3 times for this to work. Hope this helps.

TV seems to reset it's settings for some reason (it happened to me with similar TV - LT-32A80SU). I have found the way to solve this situation - service menu.

Press button "i" and "mute" on remote at the same time - service menu should appear. Now press 8 and there should be menu that allows to change few advanced features. Pressing down and up arrows allows to navigate, pressing right and left arrows changes values. You have to change "dual HDMI" to YES (this will enable second HDMI port) and change "remocon" to other option available (this will change how the remote behaves). Save settings by pressing OK button. Now you can leave service menu by pressing "i" button twice. You should now be able to use your TV like before.

Remember - these are instructions for my TV and they worked for me but playing with service menu can be dangerous so you're doing it at your own risk. Ask JVS support if you're not sure what to do.

If you swapped directv receivers and the problem followed to a different tv then there is something wrong with the directv receiver. Need to run satellite setup again on this receiver to fix. repeat satellite setup is accessible through the setup submenu by pressing menu from the directv remote. look under satellite submenu once in setup

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.
