[sci.electronics] Elderly CD players misbehaving

Hi,
    I have an old (5 years) CD player that jumps while playing most CDs.
It's not the CDs. I suspect either the laser is dying or the tracking is
off. Anyone know how to tune the tracking, preferably without an oscilloscope
(as then I'd need to know where to wire it to) ? There are a number of small
potentiometers at the side of the board. I've played with them (minimally)
and can always make it worse ...

As a clue, it's recently started playing the start of some CDs at double
speed ... !

Thanks,
