the problem is with the micro processor on the back of the fx-1169a board (gm-p420ug) this is the board the inputs connect to . yours may be a diffrent p/n due to yours bein a "e" extention model. to repair this problem you need to remove the processor from the socket, remove the socket from the board and solder the processor onto the board. the processor is ic002 on the back side the problem is thermal in nature due to cold solder joints on the socket. i have fixed this problem many times by using this method.

SOURCE: JVC LT-32DS75SJ issue with HDMI
1. Turn ON TV
2. Connect PS3 to TV HDMI input
3. select TV HDMI input for PS3
4. turn OFF PS3 if it is ON
5. Press and hold the [I/O]Power button until the PS3 until you get the "HDMI Detected" message.
Also, this TV has a circuit that deactivates the HDMI if the rear cover is removed. It is possible the HDMI may have been turned OFF. This is reset in the service menu of the TV.

This TV has a sensor that deactivates the inputs when light is sensed. perform this procedure to correct it:
1. press "Sleep" button on the remote
2. while "Sleep timer 0" is showing, simultanuously press "display" and "video" button on the remote
3. you should be in the Service menu of the TV....if not you should do the steps again
4. select "self check" from the displayed options.
5. when the "self check" menu is displayed, Power off the TV.
6. unplug and replug the TV.
7. Check the digital input.
if the input never worked for you, it is possible that you have the DVD/Bluray/whatever set up incorrectly. I don't think this TV accepts 1080P resolution so make sure it is set to 1080i or lower

Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.
