Sl-10

[hansdo]

Hello guys,
I have bought a SL-10 with a defect .
If I pushed the start or cue button the platter goes turning on the right speed , normally then you hear the relais from the arm cueing en the arm moves. but now the arm and cueing do'nt work. If you move the arm by turning the pulley and pressed the stop button ,the arm returns to the rest position and the platter stop turning. I have try the arm motor board in a good SL-10 and there it works oke , the same for the arm itselves. So the fault must be in the motor control board ,under the platter.Normally the armboard get a message from the platter if it turnes on the right speed ,I think that this signal is missing . Who can help ?
greetings Hans

I see a collection of Technics linears listed...... The first one I bought myself 30 years ago ,a few months ago I saw a Q1 and that one is better than a DL-1 so I bought it . Then I saw on Ebay from 1 person a SL-7 and SL-10 ,both with a defect. The SL-10 seems to be a brand new one ,the defect were small and they works perfectly. This weekend a bought from 1 person a SL-10 and aSL-15 with a defect. The SL-15 works fine now but the SL-10 I'am still working on.
Have you downloaded the Owners and Service manuals for the SL-10 from the VE Library?

This thread although for an SL-7 also applies in principal to the SL-10.

Short story, check the tonearm drive belt, de-grease and relube the tonearm drive system, exercise tonearm drive motor using a 9VDC battery in both directions and exercise / push all buttons (don't cha just love doing that? anyway? )

Try cleaning the connectors to / from arm motor board to make sure there is positive contact as it relies on information from MB for proper logic function.

Good luck.

Do you know how I can check the big chips on the motor board ?

yes,I bought 30 years ago a SL-DL1 ,few months ago I see a Q1 which is better than the DL . Then I saw on Ebay a SL-7 and SL-10 from 1 owner both with a defect . The SL-10 seems brand new. They works perfectly now. Nearby mine town I bought a SL-15 and SL-10 both defected. The SL-15 is working fine now only the SL-10 not yet.

The chip(s) is leveraged over several Technics tts. I've come across TP and corresponding values in other Technics service manuals but can't remember where / which tts they are shown.

Thanks to the service manuel from vinylengine and a good working SL-10 I have found in what part of the board the solution must be found and the SL-10 is working good now . Maybe it is good to fill the manuel with the value's wich can be found on the connection between the platter board and the arm board. If there is one pen with a different value then you know where to search, just follow the lead.
