I’m a new poster in hopes of gaining some much needed wisdon. I have a light-on 5115 which has a terrible intermittent hiss in the audio. It isn’t there all the time, but when it is there it goes on the recorded dvd. Any thoughts? Also, has anyone changed out the dvd drive sucessfully on a 5115 or 5116? I took the cover off and it looks a little perplexing. Thanks for the forum.
From what you are saying, it most likely come from the electronic circuit. Replacing the drive itself may not be a solution.
I would first check all the outside cable connection, making sure the cables are sound and have a good connection.
If that does not help, than back to a repair shop or getting new unit, whatever is cheaper.
