I had the problem on a very old version of the TDM card (brown card)  I contacted Digium and after a few WTF's they sent me a shiny new blue card that to this day is still blue!!!
 
Contact your reseller or Digium directly they always stand behind their products.
 
I would double check for ground loops and good connectivity on the molex connector.

Subject: [Asterisk-Users] Melting TDM card

Yesterday FedEx brought me my new TDM400P with 4 FXS modules.  I installed it (in the correct type PCI slot) , plugged in the power, and fired up the system.  A few minutes later everyone in the office is complaining about something burning.  I open the server again, and the top of the Digium card is black, slightly deformed, and looks and smells of melted plastic.  The funny thing is…the card still works just fine (as far as my testing has revealed, anyway.  I haven’t tried ringing the lines, just placing calls from them).  Maybe this is how Digium knows if a card is returned used or not?

 

Still, nothing was touching the card, it was in the right slot, and it was installed as instructed.  Beats me what happened.  I’m just not sure I like spending hundreds of dollars on a card that arcs and melts when I install it – even if it continues to work.

 

Has anyone else had this problem with the TDM cards?
