Technics 1210 Stroble Flicker and Low torque

As everything was normal before you started the work, I'm thinking you might have disturbed something. Such as caused a wiring plug to come loose. Maybe even a bad solder joint somewhere?

You need to move the tone arm across to the record for it to start. Cheers john

how do you know theres power to the unit if theirs no strobe light pitch adjuster light & the platter doesn't spin?
the power comes in & to the transformer first,then through the strobe switch, the transformer is what blows when you short the target light out.....i've seen this many a time when people try & change the target lights to blue neon.

1, The regulator circuit has failed, usually transistors Q2, Q3 and zener diode D3.

OR

2, The drive I.C (I.C101 / AN6675) has failed, this can be natural failure but also can happen if the deck is turned on and started with the platter removed.

The bridge rectifier is shorted with gives Q1 and Q2 the appearance of being shorted and blowing the 15 amp ceramic fuse

hi! there is a problem inside your turntable (on the main board) check the components  TRANSISTOR    Q2, Q3,  ZENER DIODE   D3..

CHANGE IT IF POSSIBLE..

hi there,

you can try to this store to order the parts to be replaced part number & description was also indicated in HERE.

just let me know, for further assistance,

Your wires are crossed. You'll have to switch them out. Make sure when you put the wires back together, that they are covered properly with either electrical tape, or heat shrink tube. If any part of the wire is exposed and it touches the cabinet, it will ground/short out your turntable, and you'll have an even bigger and more expensive issue to fix.

No flying screws on the lamp (on this model anyway) you should have no problems!
Good luck!

No, this has nothing to do with the fuses. The problem lies with one or a combination of faulty IC's (integrated circuits). More than likely IC201 (Turntable Control IC), but IC101 (Turntable Drive) and IC301 (Pitch Control IC) will also cause this sort of issue.

Also take a look at R213, it generally gets very hot, and you can tell by looking at it and seeing discoloration, and might be the starting point to this mess. It's good to replace this as well, while your at it - however, it is no longer available from the manufacturer, so you'll have to match up the rating for it. In addition, take a look at Q2 and Q3 (Regulators), those also tend to burn out at the same time.

Good luck.
