Strange Technic 1210 problem - can anyone help?
Strange Technic 1210 problem - can anyone help? Posted on: 21.03.2013 by Manda Pisel Hey,I'm experiencing a very weird problem when I turn one of my technic 1210 mk2s on and I have absolutely no clue as to what's causing it. Rather than explain it, I have uploaded a video showing what happens. Basically, it seems as if there's low torque, the platter judders backwards and forwards and the LEDs flicker. It's as if there's not enough power. Can anyone offer any advice, or suggest what could be causing the problem? Thanks, Adam | |

Corie Murtagh 25.03.2013 | well xone on the front page says to replace the pitch fader. but try and clean it first to see if that helps at all |
Manda Pisel 23.03.2013 | I have just replaced:- 1 x 2SD1265 (Q1) 2 x 2SD637-R (Q2 & Q3) 1 x 5V1 Zener diode (D3) And the problem still persists. So that pretty much rules out the power supply regulation. Can anyone suggest anything else? |

Lisa Lochotzki 21.03.2013 | I'd guess the problem is worst after, say 20-30 minutes and don't happen when the pitch is at 0%? Really common problem usually caused by some defective components on the main board. Usually not too expensive to fix in any good service center. |
Hayden Raugh 21.03.2013 | try this mate... take the platter of the spindler, and check around the magnet for build up of dirty and grease, also give the bottom of the platter a good wipe. unscrew the plastic cover to the main part of the 1210's companents check the power supply is soldered to the chipboard properly. i use a can of compressed air to blow away any debri.... after that check the powersupply lead for any rips / tears maybe even remove them your self... i know it soudns baisic but thats what i would do... ps... nice colour... howd u get that? |
Corie Murtagh 21.03.2013 | ouch! when you play a record does it sound choppy too? have you taken the platter off to look at the motor yet? the leds flickering sounds like you have a bad power source. and something gripping the motor |
