Members 77inOctober Posted February 14, 2007 Members Share Posted February 14, 2007 i have a yamaha emx660 powered mixer and it doesn't turn on, hit the switch and no light or fan or signal. anybody have any ideas what the problem could be? i took it to my local music store, but they charge 53 just to diagnose it, and i figured first i'd try to find out what's wrong and decide if i want to pay for the repair or something new (i'd prefer to have a mixer and power amp sepeartae, but this is an old thing my friend ddoesnt want anymore). thanks Link to comment Share on other sites More sharing options...

Well... this might be out of left field, but I've seen it before: I believe that mixer has one of those detachable computer style cords. From what I can tell, the panel mount receptacle is sized to the amperage draw, being that the "pins" in the receptacle are shorter in length in higher amperage rated receptacles, while the female sockets in of the female cord end are "deeper" in lower amperage rated cords. Point being, is if you plug a 10A (like 18ga. IEC 320-10) cord into a 15A (IEC 320-15) socket, it won't pass power... and the device won't power-up.

Members agedhorse Posted February 14, 2007 Members Share Posted February 14, 2007 That's why the repair shop charges to diagnose... it takes somebody time to figure out what's wrong, and they need to be paid for that work. No idea that would be even remotely customer serviceable. Link to comment Share on other sites More sharing options...
Members hamer Posted February 14, 2007 Members Share Posted February 14, 2007 $53.00 just to take a look and its your local music store that you support?? umm ?? Link to comment Share on other sites More sharing options...
Members hamer Posted February 14, 2007 Members Share Posted February 14, 2007 im sure you done all this,check the fuse(sometimes its inside) sometime if you look inside it could be a lose wire? Link to comment Share on other sites More sharing options...
Members W. M. Hellinger Posted February 14, 2007 Members Share Posted February 14, 2007 No idea that would be even remotely customer serviceable. Maybe that mixer has a IEC 320 power inlet with an integrated fuse? If so, maybe the fuse is blown, and replacing it might just blow again (cause the output transformers are shorted)... but I bought more than one piece of used gear that was DOA, just to find the fuse had been removed (for undetermined reasons), but replacing it brought the unit back to life. I guess that is one possible customer serviceable item... maybe? Link to comment Share on other sites More sharing options...
Members pro1-54 Posted February 14, 2007 Members Share Posted February 14, 2007 1- leave the mixer unplugged2 -there are 3 screws on each side on the back of the mixer. Remove them and pull the back cover off using the plastic hooks the power cord wraps around3 - You should see some fuse holders. If you have a friend with a multimeter, check to see if they're blown. If the fuses are good then you can also check the power cord and the on/off switch with the multimeter. Beyond that I would take it to someone who knows the mixer.

Members agedhorse Posted February 15, 2007 Members Share Posted February 15, 2007 If the fuses are bad, do not replace them. Replacing them without proper precautions upon powering up can cause a lot more damage. Yeah, it costs a lot of money to run and staff a good repair shop. I am making the assumption it's a good shop thoough. Link to comment Share on other sites More sharing options...
Members 77inOctober Posted February 15, 2007 Author Members Share Posted February 15, 2007 yeah i understand the charge for labor and such, but they shouldn't call it a deposit, because i was under the assumption it could be reimbursed. and there are only 2 guys there that are cool, and when i walked and asked the young kid at the desk if the one friend was working, the kid got uppity and said "so, what is chris the only guy you do deals with?" and i looked him in dead in the face and said "he's my friend and i wanted to say hi" it's one thing to be jerk where you work, but if you're going to deal with customer's upfront, they should definately work on their people skills. anyway, more to the point, i got out my drill and such, and the majority of the screws are all ready stripped so i can't take the back panel off. i think it's maybe time that i retire it and spend money ona good mixer and amp. oh well...
