All of the HDMI ports on my JVC lcd tv are not working.

Tried replacing the HDMI cord, but none of the 3 ports work - all i get is a weak signal graphic.

    It is a 47inch JVC LCD with 3 HDMI ports in the back. None of them work when I try to connect my HD DVD player with a cable that I know works (tested it and the DVD player on another TV).

    I have seen elsewhere about needing to reset the HDMI but can't figure out how to do that or even how to access the system menu on this TV to try and do a system check.

    The order of powering up the TV and DVD can be important. It shouldn't matter but some handshakes are sensitive. Have you tried each first?-Ken

    What is your signal source? Why 3 ports? Amazon says "Dual HDMI v1.3a Input".-Ken

I had the same problem on mine. It is a factory defect. It means your HD box that controls HDMI, USB, and RED GREEN BLUE component. Usually the red, green, blue, (720 HD) component is still functional, but the HDMI and USB are shot and can only be replaced not repaired. If your warranty is still valid and you have your receipt call JVC and they will give you the number to a certified warranty repairman. If you do not have the receipt they will not fix it. If you do not have the warranty and decide to repair it yourself or send it out, the fix is not difficult but it is costly. The box is about $1000.00 and the labor varies. The last option is to sell it for parts. If you decide to do this I will purchase the broken television from you. But if you have your warranty info there is nothing to worry about.

I have a 2009 Lg 37lh30 Tv and for the most part it works until recently. I am now getting a HDCP rejection when using an Apple tv or Roku and no screen when using my bluRay Player (which use to work


Some TV's & cables are not HDCP compliant . Sometimes you can replace the cable to fix the problem & other times you have to replace the tv because its not HDCP compliant . First check to see if your tv is HDCP compliant .

Westinghouse 1080P 42" LCD TV - HDMI stopped working


I know this is late, but this happens frequently. If anyone else has the same problem try unplugging the TV for 60 seconds. Plug it back in and then hold the power button down for 30 seconds. That will reset the TV.
You should see the Westinghouse logo come up and the HDMI should work. This has happened twice with my TV in 1 year.

1. Turn ON TV
2. Connect HDMI from TV to PS3
3. Select the correct HDMI input on the TV for the PS3(important)
4.Turn OFF PS3 if it is ON.
5. hold [I/O] Power button on PS3
6. Wait about 5 second and you should get the "HDMI Detected" or some similar message.
7. Configure the HDMI output for the PS3

Also, If you set the PS3 to "auto" for hdmi, it may set the resolution to 1080i. You may want to deselect everthing but the 1080P.

No video input -- all ports -- for JVC LT-37X688


JVC may allow warranty exception or some accomodation for 15 days out. You have 2 seperate issues

1. White lines spreading is probably a video process problem. I think this TV has 3 Boards inside. Middle one is most likely suspect followed by the one on the Right

2. HDMI input not working is because they were turned OFF. JVC TV's have a sensor that will shut off the HDMI if the TV's back cover is removed. This must be reset in the Service Menu.
