Left on DVD Too long ? sad mistake ?

Hello ,

I did a silly thing I have my cable TV connected to the dvd player-recorder[ a panasonic] and I left it on for months . I was not using it but it was on . I went to put a dvd in just now and it did not respond to the open or close command to put the dvd in . I was able to turn it off by the remote and hope it will cool off or mend the problem .
It didn't feel very hot, I really hope I didn't burn anything out .

I would very much appreciate any suggestions .

Alex
