Technics sl1200mk-2 turntable shorted

I have 2 technics that shorted, well one was finished with led installation, it fried, the other had finished led install with regulator, i dropped the pop up light on table and it sparked and shorted. any idea of what is out? nothing shows any burn of any kind one table has fuses and the other no fuses, both probably need transformers.

    The euro table had a switch set at 115Volts, and was wired correctly just no regulator was attached when finished and shortly after powering on it when out and smelled. turned over the mother board and seen it was from 1988 august. old bought it used.200.00 but the other i had purchased in 98 and had finished the strobe, 33/45. pitch was finishing on the regulator for the pop up LED the light didn't com on but all the others did so i turned off the unit took out the pop up light and looked at it the resistor was soldered wrong. So i took off the covering and screw and I dropped the lamp covering over the power circuit by accident and sparks came up and smoke this table does not have fuses, the other looked in bad shape since it was from 1988? Before I started on this i noticed after putting in the strobe the platter was turning counter clock wise when powered on I couldn't make since of it i figured it would correct it's self when the popup light was finished. instead i ended up with 2 burnt sl12000mk-2's ouch. I still have my new table that i haven't touched since putting the 33/45, strobe and pitch light on. i have not put in the pop up light and left this table alone to work on older tables to learn but i would appreciate any advise. on either table thanks so much.

    It was making weird sounds when rocking back in forth the platter that is before i worked on the pop up led. before i dropped the lamp cover. I have a extra regulator +5V 3 prong left-live middle ground right output. is how i did the wiring on the pop up light. and the spliced wires going to the plug in on the mother board. but the reason it burned out is by me dropping the lamp cover over the power circut board and transformer, i think it might be the transformer. can you get this at radio shack.

SOURCE: 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.

SOURCE: Technics SL-1200MK2 Turntable i need to replace the on off switch on a mk2 technics 1200 any

The part is located HERE - but you will have to take apart your turntable from the bottom in order to replace it. It's not very hard, but if your not mechanically inclined, I would not suggest doing it, as you could cause more damage.

SOURCE: Connect turntables(technics SL1210MK5) to a mixer?

None. The cables are already attached to the turntable. They are hard wired to the unit. The red & White cable. Just connect to the PHONO INPUT on your DJ MIXER, and connect the thin ground wire to the GROUND terminal on the mixer. That's it your ready to go.

SOURCE: Technics sl-1610 mk 2 turntable

OK. Whoever stated that the Technics SL-1610MK2 is direct drive, probably did not notice the "belt" being sold for only $14.90 online. If this belt is being sold, there is a strong possiblility that this turntable is belt driven, so maybe the belt just slipped off or busted. order a belt and replace. Good Luck.

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 plugged my turntable into a 220 surge protector using an adapter. When I turned it on the red light went out. I hope I didn't fry it. Is there a fuse in the turntable that I can replace or am I...

You have not mentioned if it was a 110 volt version turntable plugged into a 220volt outlet ??.You have not mentioned the model of the turntable too///.
Any way most of the Technics have a glass fuse if you turn the player over and remove the bottom cover. Remember to lock the arm or even tie it up to prevent stylus damage. Typically it would be a 500mA glass fuse. Easy to replace just remember to unplug it from the wall socket before you attempt to do so.

My technics 1200 mk5 is blowing a 125V 250 mA fuse on the board just after the transformer

There must be a shorted power transistor in the power supply area. Check the voltage output of the transistor to determine which part is having a short circuit.

Fried power on technics SL 1200MK2.

If you are lucky then just the fuse may have failed - usually F1 / 250mA / 20mm type.

If your unlucky the transformer may have fried - mail me for a price [email protected]

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

Power problem

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.

I can't see the digital readout

There may have a been a slight power surge which fried either a resistor or IC inside the unit. This is NOT a self repair, and you will have to get it serviced by a professional service center.

Good Luck.

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.

Turntable grinds to a halt.

The Technics SL-BD22 is a belt driven turntable. It is most likely possible that the belt wore off, wore down, or could have spun off. The platter should have 2 holes in it. One of them should alow you to see, and replace the belt. YOu can lift the platter off the turntable via those two holes. MAKE SURE IT IS TURNED OFF AND UNPLUGGED......

You can find a replacement @

http://1200s.com/Store/PARTS-TECHNICS-TURNTABLES-Drive_Belts/c271_272_278_398/index.html

And the part should come with instructions. Those guys are very thorough.

Keep me posted.
