decisive Posted June 24, 2006 Share Posted June 24, 2006 I was cutting on thursday and suddenly the motor stopped, and now it won't start again it's an old (TTX1, but not variable torque) model, thus out of warranty (second hand anyway). Part of me wishes I'd listened to the disparagers now... anyway, the lights still come on and the electronics still work (still outputs sound as line output too), it just appears that the motor has stopped responding to the start/stop buttons. Does this sound like the error that the 'cisco mod' could solve? I'd rather try it first before going to get it fixed for god knows how much... ta Quote Link to comment Share on other sites More sharing options...
Liam Posted June 25, 2006 Share Posted June 25, 2006 Get in touch with Numark ASAP. The TTX has numerous known faults so there's a good chance that you can get it repaired, warranty or otherwise. Quote Link to comment Share on other sites More sharing options...
stalk Posted June 25, 2006 Share Posted June 25, 2006 this happened to quite a lot of people, including me. It can be fixed without problem. Cisco El Nino posted the repair manual on the old Asis site and Reezy just posted this on D-Styles' board a while ago.TTX repairI did this mod and it worked like a charm. In addition, to make things easier, you will need pliers to get the IC out of the PCB because it sits in there pretty tightly. I tried soldering at 280°C but it took forever for the solder to melt, so I went up to about 350°C and it worked. Quote Link to comment Share on other sites More sharing options...
decisive Posted June 25, 2006 Author Share Posted June 25, 2006 cheers for the replies lads, I've sent numark a message detailing the problem (although i was in a friendly drunk mood last night so i think i might have been a little bit forgiving!), if there's nothing they can/will do, I'll brave the repair myself...

Liam Posted June 25, 2006 Share Posted June 25, 2006 Stalk, watch out with using such high temperatures, excessive heat WILL damage components. Also: handy tip... remove components with multiple legs (like the IC) by holding a razor blade in some pliers and heating it in a blowtorch, then holding it against the legs to heat all the points at once. Works a charm. FYI, the only component on the 1200 that gets reasonably hot (a voltage reg) is thermal paste'd and screwed to about seven or eight kilos of die cast aluminium, which has thermal characteristics only marginally inferior to copper. 12's last a long time, and not wihout good reason... Decisive mate, you're only over in Hull right? I should be in York all summer man so if you're about perhaps we can get skrizznatch nerdy on it.

stalk Posted June 25, 2006 Share Posted June 25, 2006 I know that part is temp sensitive but soldering at 280° was a pain in the ass. I gave up after half an hour because the solder wouldn't melt enough. I could've used different solder but I didn't have any other available. it worked with 350° in my case and I put a good deal of thermal paste on the IC before screwing everything together again. but yes, you need to be careful, that's for sure. best thing is to wait a few minutes after each leg soldered.Good looking out on the advice with the razorblade.

Guest rasteri Posted June 25, 2006 Share Posted June 25, 2006 I have a problem with one of my TTXs, in that it only seems to have power when the platter is at certain angles. And sometimes it just stops randomly. It's still usable, but annoying. I may give this mod a go - it should be possible to replace the chip with an IC socket, then soldering at high heats and replacing the chip in the future shouldn't be a problem.

I'll let you know if I'm up north again though... paayce Quote Link to comment Share on other sites More sharing options...
