[quote user="joeyboygolf"] My 6000 clicks, which I think is the end stop microswitch deactivating! [/quote] Yes, but it doesn't click pressing "PLAY/START" in itself! Back to the topic, I read in a post or two that there should be a spring inside the bearing? Maybe around the recess at the bottom of the shaft? Jacques

[quote user="Dillen"] Don't know if you are aware that it's an IR LED. [/quote] Ah yes! It's because I saw all these posts on how to replace the bulb with a white LED, I was confused! And the service manual only says "LED"! Thanks Martin! Jacques

Hi, The LED in the carriage position circuit is good but it doesn't light up. The mechanical switch works. Any ideas? Is this related to the previous problem? I can't find any schematics for my deck (SN 054865) which makes it harder to comprehend! Jacques

Right then. 2N1711 2N2907 don't work at all here. The BC142/143 used here are audio drivers. I've ordered 2 of each. Jacques

Thanks Martin, I had got that... One hour later... Done! but no cigar... Same symptoms. Exactly. Jacques

No, voltage arrives at the first and second transistor (+21.8 v at collectors and +14 v or so at base of the first transistor) when I press 'play' but somehow never manages to power it through. No voltage at the emitter of the second transistor (metal), however tested good. The motor works normally when I press 'back' or 'stop'

I have tested the electronic switch: it is alright in all its functions.

Okay, the deck lights up when I press "play", the motor turns, but it stops as soon as I release the button. I will check the diodes and come back to you. Thanks

The transistors are all good... What next please? I have re-soldered everything and still nothing. I just don't get it. I've been studying the diagram (not that complicated on the paper!) but I can't find anything. By the way, my 4002 has some funny kind of phototransistor (in a transparent TO92!). Must be the ancestor of all this! Any ideas

Thank you for your time Martin! This is my board exactly. What equivalents do you advise? For instance, BC 547/557 for command, 2N 2222/2907 for power? (you guessed, I have them at hand!) Jacques
