Turntable hesitates when turned on. sometimes the 33rpm and the 45rpm will light up at the same time and the turntable will go very fast . some time the light on the on and off switch will go on and off.

Re: technics 1200 mk2
Sounds like a short on the pcb, one of the IC's could have gone bad, or
the 33/45 have shorted out. Unless you have the proper tools i can only
direct you to who you could send it to or order the part(s) from. If
youre good at soldering and can work in square inch spaces, go for..

Hello the turn table has two speeds. 45rpm and 33rpm (rotations per minute) If you are playing a record that takes up the entire turntable you need to set it on 33rpm. For the records that only take up half of the turntable you want to set it on 45rpm. Setting the turntable on the wrong setting for a certain size record can make the record play to fast of to slow.
Try plugging it into a different power point. The problem is with the power supply fluctuating. You can eliminate that with a UPS, here is a link to wiki http://en.wikipedia.org/wiki/Uninterruptible_power_supply
Mismatch speeds on older turntables is normally due to either 1) a kink in the speed switch mechanism or 2) a hardening and slipping of the rubber drive wheel.
A very small motor with a chamfered shaft drives the rubber drive wheel, and the wheel is moved by the speed control up and down the drive shaft to produce various rpm speeds.
In your case, it's likely turning at 45rpm because it isn't settling onto the 33rpm part of the shaft.
Piddle with the speed control, then count the speed (number of turns in a minute) You'll figure it out!
I don't know if this model is direct driven or by belt. If it's belt driven then the belt could be fitted incorrectly, or faulty. Another possibilty is that there's a fault in the motor control circuit.
Check that the lever is actually making the contact with the 45 rpm switch position and completing the circuit as it would seem everything else works. The only other thing it could be is a break on the pcb, but that is unlikely.
need to know if it powers up. Does it try to spin, do you hear it trying to spin? More than likely the on/off switch went bad. No, I am not referring to the ON/OFF knob. THere is a switch this engages when turned. The part is S601. You might also want to replace the Start/Stop switch as well. If neither work, then the issue is on the main PC board, and probably IC101, or IC201 with the problem. At this stage, you will have to have a service tech look at your unit.
