I have owned a D2 for just over a year. I am an older person who has used the unit very sparingly. After returning from New Zealand the unit would not power up. I tried many of the "fixes" on this forum and finally gave up. I sent the unit into Cowon for repairs. I received a reply a few days later from PayPal wanting $67 to replace the circuit board! I feel this is outrageous to have a unit that has seen little use need over half the value of a new unit to be repaired. Is this common to the 16GB D2? Can anyone help me with an email address to complain or state my case to Cowon? I have tried some of the contacts I could find to Cowon to no avail.
