I had the heat issue with one of my players. I sent it in and a heat sink was added..no problems since . I had both my players modified in this way. I have had my players about 16 months. I use them about 3-4 times days a week at about two hours each day. In addition to that more hours depending on how many gigs I have for the weekends. I usually play for 4-5 hours in the club.
