Technics SL-1200 Turntable - Answered Questions & Fixed issues

There is a capacator in you pre amplifier who is not working properly , replace this and it will work again. they use most this type 100uF/35V

Could be a couple of things. Could be the alignment, weighting, tracking or all of those causing this. It could be the gain structure on your mixer is not set and is too high. Maybe that the output of the cartridge is to high for standard mm inputs

almost often a wrong set table/arm weight and a dirty needle. . i gues the last. Cleanen record

50hz hum. Turn off most of your home equipment , turn only your table on, if it still hums it\'s your transformer and that\'s too bad for your wallet. And you also don\'t have those led lights which is a fashion statement at the moment on your table, they are not quite good for causing distortion. And in your home are saving-lights. especially with dimmers and lcd plasma tv\'s a major cause of distortion. But a steady , low freq hum is your transformer and i have a stethoscope, not for that purpose:). Then you don\'t have to search. But they ain\'t cheap, the upgraded in 2009 ones.gr richard

can you be a bit more specific , do you want no music to play or else take a look on which type of music is in your pregerences coupled to which device and switch it.

More than likely either an issue with an IC (integrated circuit) on the main PCBoard such as IC301 (Pitch Control IC) or one of the Regulators like Q2 and Q3. While your at it, you might want to check IC201 (Turntable Control IC), and IC101 (Turntable Drive). Doesn't sound like anything is busted just yet, if it comes and goes. This means something is about to fail, and your just seeing the failure in action.

Good luck.

It needs to be taken apart. The bottom needs to be removed. Not an easy job if you are not mechanically inclined. There are pots inside that need to be sprayed with contact cleaner. Pots are under the knobs that control the speed. They have holes on the sides of them. You can purchase cleaner at a radio shack or electronic parts store or online.

The closest font I found is "Arial". I based it on the numerals used. I do belive the fonts for the word "Technics" is different

Hi, check to make sure the headshell is fitted properly to the tone arm and that the stylus is not damaged. Cheers john. Styluscity

You can soon find out by leaving out the EQ. Best to check the cables that connect the units.

Hi, it needs to be earthed to your mixer or amp. Cheers john

Is it a belt drive turntable? If it is then either the belt is off or broken.

a) "dirty" main power switch, comes from sparking when power switch has been used a lot (happens also with some CD/DVD players - makes them loose some power - consequently, focus and/or spindle will not work properly). Try cleaning it up or replacing it (bypassing it will tell you if the switch is really the problem).

b) bad contact on the speed control slider (try moving it while slightly pressing it downwards, see if there is any change, if there is, have it cleaned up or replaced)

c) a problem with electronic speed control, possibly a loose solder connection or a bad capacitor somewhere in the speed control circuitry. If the circuit has fuses in it check if they are all ok. I once had a problem with a turntable that had a fuse "partially" blown (people were using the turntable a lot for "scratching" which overheated the fuse but hadn't blown it out, yet it changed in resistance from zero ohms to a few hundred ohms - the turntable began to **** and the speed was changing).

d) none of the above, it could be something else that i can't think of right now

hope ya get it workin'

Most likley the pitch fader has worn / become faulty.
Look here for a new one :-

Clearly there IS a setup issue. Take serrato out of the loop for the moment and the mixer. Plug each deck (one at a time) into a hifi with a MM Phono input. Are you getting stereo? If yes, you know the decks are ok. Now reset the mixer completey. All eqs and pans including volumes to 12 o clock position and volumes to 0.Make sure you connect deck one to a red and white of one phono input channel. Do not use 1 channel from phono and 1 from line. Use both left and right of the phono chanels.Ok, now hook up the mixer to the amp. Keep the x-fader on channel 1 and concentrate getting a good stereo signal from this one chanel. Now do the same for the other cahnnel.This should hae helped you to get up an running, if not narrow down the problem.

can you be more precise. At the moment it sounds like you cant beat match. that is not the turntable's fault

Your tonearm might be damaged.

you changed it back and it doesnt work? theres a little switch that is 120 or 240 or something like that US is 120 uk is like 140

Use the slide on the pitch control to move forward or backward until the dots stay steady. If it is a little old the quartz control won't work as well.
