Channel not working

Can you be more specific? which light isnt on? the power light, the popup light, or the pitch fader light? and what do you mean by the channel? are you using mutiple technics? and are you using serato?

If all the mechanics work as they should , you're in good shape. The right and left audio channels don't even have any circuitry, so the problem must be with the cartridge. (or bad old cables). Take out the cartridge and rub the connectors with a pencil eraser to clean them. Wipe with a rag and reinstall the cartridge...The missing channel should be back. If not you may have to change your cables. (there are tons of youtube video walkthrough.) It's not that hard and you get to upgrade the cheap cables Technics gives you. :)

As for the light, I assume you mean the pop up light? All you need to do is order a new bulb. I suggest LEDs these days. Longer lifespan and BRIGHT as hell. Heck if you feel comfortable with a soldering iron, get the whole LED kit. Any color you want and it replaces all the stock lights with your custom color for about $10. Cool huh?

If not you can just replace it with the original incandescent bulb for about $10 on ebay (oem always costs more than custom)

If the light you were talking about was the strobe, you will need to learn to solder or just buy a new motor board on ebay. They go for about $120, but then problem solved. I hope this helped.
