Re: tone arm and stylus light spare and replacent .
For Technics parts, check www.1200s.com, for a service center in your area, check the Panasonic web site (parent company of Technics): http://www.panasonic.co.uk/customer-Support/svc-dealer-locator.asp
As for instructions on doing this, it's not an easy fix. You have to solder 5 very thin (as thin as dental floss) to a circuit board, and they don't leave much room for error. Oh, and the circuit board is discontinued, so if you damage the board due to self-repair, you can't have it replaced. So, thing twice before attempting this repair yourself.
Hope this helps!

Hi, at the base of the tonearm you will find a rubber grommet. Remove the grommet and insert a flat blade screwdriver. Adjust screw to the right until arm lands in correct position. Cheers john. Stylus City.
I've got the same problem. When you put therecord on, spin it from the centre, and it will release the mechanism inside,this is what I do, and it works fine. I think the problem is that there are twoplates under the turntable, and there was grease between them, after a few goesthe grease disappears, causing the problem.
Look up underneath the mechanism. You've moved the tone arm with respect to the bracket beneath it (which closes the trip switch). Select a record...turn the machine off...then look up under whilst someone moves the tone arm and you will see what it is attched to. If you are lucky you can hold that tight and gently move the arm back the other way a bit.
Old decks have BAD RCA connectors. I would start there first. Its easy to solder them in... but you have to take the decks apart. As well as look at the leads that run through the tone arm down into the decks.
On some record players there is an adjusting screw at the back of the
tone arm that adjusts the tone arm drop in location but I don't think
it will adjust the pick up point. That is controled by a steel
rod under the record player deck that moves over and pushes a little
trip lever near the center of the platter so that a gear is engauged
and the end of record cycle is started. I'm not sure but you may
be able to find an adjustment under the deck that is near the rotation
point of the tone arm that will adjust that rod so that it will pickup
later. Hope this helps some.
It's a bit after Jim's post, however I had what appears to have been the same problem with my LX770 after it had been stored in the loft for quite a few years.
I found the problem to be caused by the tone arm mechanisms stalling - The band that was associated with lifting the arm had turned to a black gunge and was not allowing the motor to rotate, also the motor associated with moving the arm backwards and forwards was struggling to turn.
I cleaned the tone lifting pulleys and replaced with a small elastic band (for a temporary fix). This was a little fiddly as you have to take off a spring and a couple of gears to get the new band in place. I cleaned the runners and cleaned off the grease on the worm gears associated with the arm tracking (as I suspected it may be more viscus than originally installed), lightly oiled the tone arm tracking gears. It still seamed to take an amount of helping the tracking arm gears until they were able to move freely. With the tone arm mechanisms working properly the whole unit now seams to be working.
Top tips if you attempt this:
WARNING - If the unit is plugged in, the transformer and high voltage wires are live regardless of whether the on button is on or off on the front of the record deck. PLEASE do not take any of my comments as recommendation you should ever do anything with the unit plugged in!
Remove the little stylus carrier before you start taking the player to pieces - saves damaging it!
Remove the record mat and aluminium platter before turning the unit upside down.
Manually push the tone arm to about 0.5cm from its furthest travel - so you can remove the tone arm mechanism plate. May be a little stiff as the wires have to slide of the pulleys for the tone arm to be pushed.
To access the tone arm mechanisms, remove the main bottom plate (and greasy spring), then undo the screws which hold on the rear undertray. With the decks buttons toward you, you should then be able to lift the rear tray slightly and tilt the tray towards you to expose the tone arm mechanisms.
You shouldn't need to remove the circuit board with the control buttons on the front of the unit.
After getting it going, I found that I needed a Phono preamp to get the signal strength necessary to use the deck for transferring vinyl to my PC.
