I've had this problem twice and each time it has needed a replacement laser sledge at a cost of £100 (€150 +/-) fitted. I've now given up and bought a new stereo so am selling my entire L7 system (MD, CD, tuner , cassette, stand). It's a shame as it's elegant and neat, but I think the design is seriously flawed as such a failure rate in light usage is not really very good. I don't know if you can replace the sledge yourself - I doubt it.
