I have Panasonic model TH-50PZ80U plasma. Cable box gives error message EF01. All 3 HDMI ports are not working. R/G/W ports work. Have had cable checked out and replaced Connecting the box with another HDMI TV works.

Is ther some way to reactivate the HDMI ports?
Hello my name is Anthony
Thanks for the Question

If you try another HDMI product (other than the cable)does this work or not please?

Blu-ray player does not work also. Two HDMI ports on back appear not to be working as well as HDMI on front of TV>


The mainboard will need to be replaced do you think you can do that yourself?panasonic term it the A board its the board with the actual hdmi sockets on, however you will need to get the partnumber found on the board itself then come back here with that I will then look for a board for you.

Let me know if you can do this.

If you need a tech to do it will locate a tech in your area charging about $300
