Hi I got a Sharp MT180E(S) about a year ago. In the last few months however it has stopped working. Whenever I try to play a minidisc, it starts up ok, but when it gets to TOC Load, it just seems to freeze, and makes a loud clicky noise and judders I cant really afford a new one at the moment, and I looked at getting it repaired at my local music shop (almost expensive as a new one). Anyone got any tips to fix this Thanks in advance Sp1d3r
