[katis74]

Hi Iam new to this forum and very happy to found it.My creative zen x- fi 16 gb was dead 5 days ago (wont recogniced from pc, led wont turn on etc).Before this happened i had noticed the last time that that the screen turning on white for 1, 2 seconds..even the player was off many times without reason .Connecting to pc the reset button couldnt fix the problem ,so i dissasembled the player .I solderd the wires keyboard loudspeaker and battery about three times cause are so little & sensitive.My main battery cant use(wires burned from solder) it any more so i use an other 3.7 v battery from rc little heli .The player has a main chip damaged or something??What do you suggest me to do?Can i fix this or it is to late.I love this player and i would like to fix.Is that possible in some way ?The firmware i used it was the stock.Can you help me? Really appreciate your interesting.Thank you .
