grhu8175 0 Report post Posted March 1, 2010 (edited) Hi all! Recently, i bought a mini3 from a online forumer and got conned.. think its spoilt... the seller changed number immediately and cant be contacted... initial advise given is that the left and right channel got short circuit.. cos now everything seems mixed together and theres no stereo seperation at all... even the highs seem distorted at times... moreover, the battery can hardly last an hr despite being charged overnight as i have no DIY experience nor the tools required... will anyone will be willing to help me repair it for a fee? Thanks:) SUPER THANKS TO JACJ once again!! he repaired it for me!! i really learnt a lot from him! great friend!! Thanks!! Jacj!

dennis28288 0 Report post Posted March 8, 2010 (edited) would anyone like to help me with this? sounds like a volume pot problem.... cos i still own 2 mini3s myself. One of its problems is that the huge volume imbalance when turning up the first quater of the pot. You can try changing the pot to something else. U can get one easily from koba, a 10k ohms integrated switch alps pot......RK0971221Z05. gd luck. Edited March 8, 2010 by dennis28288 Share this post Link to post Share on other sites
