Technics 1210 one channel not working
Technics 1210 one channel not working Posted on: 10.05.2011 by Makkins Clifton I recently bought a 1210 and a system (Ortofon QBert).Today I tested it and sadly the output of one channel is missing completely. I grabbed a voltmeter and tested the connectors inside the tonearm with the cinch-cable. There are four connectors inside the tone arm. I could successfully check the upper two of them. One of each is connected to one side of the cinch-cable. I don't know about the lower two connectors (I got no connection to any end of the cinch-cable with them). Sounds like the system is broken or may I have overlooked something? | |

| Thresa Treon 14.06.2013 | I have the same Qbert Concordes connected to my Technics 1200... and in Traktor it says Right Ch. missing... I have used 2 Shure M447s and the other Qbert concorde and all work fine w/ that turntable and the other one as well... I even sprayed the recommended Deoxit on the back contacts of the Qbert Concorde, which I didn't believe they're were necessary since I just bought them a couple of months ago... Any help with this? Thanks, Ollie |

| Shanda Takashima 07.03.2013 | almost brought new decks because I replace the phonos and it was still down on one side and couldn't work out why. thanks for this tip I just cleaned the connectors in the tone arm and now I'm back in business. Cheers for the tip saved me hundreds and the cost of new decks! LukeDaLoop |
| Lisa Lochotzki 10.05.2011 | it's a bad idea to use screwdriver on the long long, If you use a screwdriver, you scratch the contact "protective" layer, and then it will just "oxydate" faster than before. Not to mention that you'll no longer have a "Flat" and uniform contact area/surface. However, depending the shell type you used before, the contact are maybe no longer flat anyways. You want to use Q-tip (foam one = the best) with some sort of contact cleaner (without lube, isopropyl alcohol usually works, Deoxit D5 also work), then use a can of compressed air. Repeat until the contact are 100% neat. On Tonearm and Cartridge side. |

| Teresia Janusch 10.05.2011 | the lower 2 are ground. if you get the upper two then that would indicate the tonearm and cable are good it is possible that the connection between the cart and tonearm isnt clean. try looking at the 4 pins inside the tonearm, if any have dark spots, use a small screwdriver to scrap them off, also try removing the cart, lick your finger, and rub it on the pins of the cart, then screw back on |
| Neville Blackinton 10.05.2011 | I had a similar problem with one of my 1200s and I ended up having to open it up and patch the RCA cable. It had severed just inside. Not too difficult. IIRC took me about an hour or so. Hope that helps. |
