Sounds like a short. A resistor probably burned out, and is causing unregulated power to hit your system. If you look at your main PC Board, underneath the turntable platter (disconnect your turntable), and remove the board. You'll be able to look at the board, and see if there are any burn sections on the board. If so, than the components around that area will need to be replaced. Generally R213 gets burnt, and Q2, Q3 get burnt, causing this sort of issue. This is not something I would recommend fixing yourself, and I would suggest seeking professional assistance.

You might also want to take a look at your fuses, which are located on the left side on a smaller PC board. If you don't see any fuses, then your unit does not have any fuses (common) installed.

Hope this helps.

Replaced Technics 1200 bulbs w/ blue leds...all work except strobe and turntable not turning when start button depressed, something is smoking...i immediately unplugged...help please?


Sorry to say but it sounds like one of two things. Either A. You somehow may have exposed some nearby wire that allowed for it to touch up against a metallic part of your mixer causing an electrical fire or almost fire. B. The particular capacitor that regulates the amount of voltage to course throughtout your turntable was drawing way more than specified due to the upgraded blue LED's that they themselves may be spec'd much to high for the Technics.

I own a SL1200 MKII and when the light "turn on" in the pitch control slider (green LED) the speed is not correct (big dots on platter move slightly) .Could you please give me some tips to solve...


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.

SL-1200 Turntable: My brand new Technics 1200 MK2 sounds wobbly when ...


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

When i turn on my technic 1200 turntable it the lights flicker and looses audio sometimes


Hi, i doubt the 2 are related as the T 1200 doesnt have a preamp, only speed control.

Maybe try checking to if there are any loose ground wires in the turntable (ONLY if you are comfortable to open)

Other than that it the sound issue might be either on the head, or on the phono outs not connecting properly.

If the speed is remaining good, then the issue is just with the LEDS themselves, maybe loose solder, if it is changng pitch as well, then dry joints in the power supply/pitch control

Hope that helps

Counter clock spinning


pitch slider can cause an unstable motor (clean with can of air and switch cleaner) if it spins counter clockwise it will be the brake. there is a little screw in a hole under the platter to ajust the brake speed.

Technics SL-1200 MK2 French - does not power up


The only thing that would cause a power failure would be a faulty transformer. However, since you had issues before it went dead, it was those issues which probably put a strain on the power and eventually fried it. So, you will first have to have the power transformer replaced, then have it troubleshooted to find out what is causing the warp mode.

It shouldn't cost too much to get it fixed. For something like this, we would charge about $150-180, which would cover everything. New Technics go for $400, and used ones go for about $300 - so it's up to you.

Nothing in AZ unfortunately. But if you call any DJ rental company, they might be able to refer you to someone locally.

No control of platter speed


One of the drive circuits on the main board are faulty, and will need to be replaced. This is not an easy fix, so you will need to take it to a qualified service center for service and repair. Not an expensive fix, but a little time consuming in isolating the issue.

Pitch LED not working


LED probably burned out, or installed reverse (+/- reversed) - Or, you installed a clickless (MK3/MK5) pitch control in an MK2 turntable.

Did you do this yourself? Or did you have this professional done? If professionally, and the LED does not work, ask for your money back! This is electronics repair 101!

If you did this yourself, then more than likely you installed the LED backwards. The longer lead is the positive lead. If the LED did not burn out, you might be able to just remove it and switch it around. If it does not work, then it probably shorted (more than likely). Also make sure that none of your solder is touching. This could cause a bad short to your entire turntable. So you want to becareful.

If you need any further assistance, feel free to give our service dept a call. We are masters with the 1200s, and fix over 300 a year! 1.866.668.1596 ext 1

Technic 1200 mk2 turntable wont spin


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.
