I have checked continuity from cartridge pins to soldered wires inside turntable and from soldered wires to left & right phono plugs and that is all okay.
To really be sure, under a microscope to look at the diamiond, but i haven\'t seen one channel oke and one chanel no sound. Then it should allways makes sound , only ckrackling. So be sure your wires are fit by tightening the connection and measure your output till the last connection with your stylus and move your connections a bit , if that\'s allright , then is it a cable or input from something outside your tt. But have you checked it also with first cleaning your needle well and another record and lift each side of the turntable a bit. Sometimes is one dust particle enough, even with a new stylus. Is your output line or phono? O a technics, take the whole needle out and those fours pins you have to lubricate with right stuf ( a tiny bit ) and move them in and out and you havent cheked the connection with your om/concorde, but i think that one pin won\'t come out totally, so pull a bit ( after lubrication ) push them all inside and watch if they come all four back. And pls replace those terrible quality rca cables from technics, they are crap and a nice pair from another brand is only 30 euro a pair, but you needle ain\'t broke for sure and does it work with another unit?.......(still clean and lubricate the stuff).I hear from you.

If you are certain the new leads/RCA cables and the soldering work was done properly, and you've determined that the issue is from the turntable and not your mixer.
Then there are 2 other factors that could be causing this issue:
1) Bad Tonearm - look inside the tonearm, where the cartridge/headshell mounts. You'll see 4 prongs. Make sure those prongs are protruding and they all look even. They must also be a nice shiny brass color. If they are dull and/or black, try cleaning them out with an contact cleaner (CAIG Lab DE-OXIT works good) made for electronic components. If any of the prongs appear to be pressed in, try to see if you can get it to bounce back. Those prongs are spring loaded, and sometimes the springs get misaligned. Of course, they also tend to dislodge. If that's the case, then you will need to replace the tonearm altogether.
2) Faulty Cartridge / Headshell - Make sure your cartridge & headshell work properly. The easiest way to do this, is to swap your cartridge with a working one. If you have 2 turntables, just swap them out, and see if that changes anything.
I am going to say, it's more than likely a tonearm issue. There really isn't anything else, other than the Tonearm and RCA's which would cause sound issues. The Circuit board will not affect your sound, unless you burned it, or damaged it in some other fashion when replacing the RCA cables.
As for a Service Center in the UK, not sure of any, but you can contact Panasonic, which is the parent company of Technics - www.panasonic.co.uk - go to the Support Section for a list of auth service centers in your area.

I have had the same problem on my 1210 MKII. I have taken it apart a number of times to replace the original lights with LED's, and naturally thought I messed something up in the reassembly. I actually found that the problem was in the connection between the tone-arm and the pick-up "housing".(Pardon my bad english) There is a little rubber band in between, and sometimes you have to unscrew the "housing" flip the rubber band, and screw it back on pretty hard. Also try cleaning the four contact pins before screwing it back on. I have heard of quite a few having this problem. A pretty obvious thing to do, but I had not thought of it, and it would have saved my from taking the entire machine apart several times.
Good Luck

is the wire loose on either end? sometimes the electrical plugs can cause noise due to resistance, so trying different outlets might help too

hi,
Here is the wiring of the turntable RCA plug ( RCA wire will have 4 connections like red and its outer wire then White and its outer wire.). connect these as follows.
For right channel
Red wire from the turntable to the red center wire of the RCA plug
Green wire from the turntable to the outer wire with red wire of the RCA plug
For left channel
White wire from the turntable to the white center wire of the RCA plug
Blue wire from the turntable to the outer wire with White wire of the RCA plug
OK
