First of all, thank you for all your help. I just checked my adapter... it's definitely an adapter problem. I can't believe I missed it.... Basically, I bought the player many years ago oversea... so the adapter is a 240V input adapter... hence, didn't work when I plugged it into the wall outlet because the voltage is 110V where I live. Do you suggest I buy a voltage converter for the adapter or just buy a regular 110V adapter? I checked the original Sony 110V adapter for this player and it's really expensive. What do I need to look for if I am buying a regular 110V adapter for the player? Input voltage, Hz, watt? Output voltage, amp? DC or AC? Does it matter if it's a no-name brand adapter? Would this adapter work fine with the player? http://www.ncix.com/products/?sku=26601&am...ufacture=Others Thanks.
