I'm not sure the question - perhaps your TV is set to the DVD2 input and it's not a DVD issue.
If so, using your TV remote, push the "input" button until you reach your desired input.

On the remote press 1 and at the same time "OK" for 5 seconds.

If you point the remote towards sensor, simultaneously hold down the number (1, 2, etc) you want AND the enter button for 5 or more seconds it should switch to the number pressed. Remember if you have a second one, make sure it's off or put towel over its remote sensor. Sue

Press functions,go `to others`select set up,go`to others`select remote control and change to dvd2.Then on the r/c press and hold enter and 2 at the same time for 3secs or more.

Check lower portion of remote, you will notice a button having 3 command modes. set it on DVD2 and operate dvd recorder with remote.

sounds like it needs to be reprogrammed get hold of manufacturer
as its new they owe you one

press stop button then the power button together the player will go off. put it on again the remote should work.

I had the problem where when i would try to use my remote, it would say "check remote2". I've got a DMR-E55. I called panasonic and they told me to hold down the "enter" and "2" button for about 10 seconds. then it worked. hope it works for you too.

push enter and hold 2
