Oh dear
one of my guys has had a glass of wine over his Dynacord tonite
Shorted the whole lot out towards the end of the gig.
Drunken punter slipped over ...£1400 quid up in smoke
Any suggestions to salvage the boards???

OK, in THEORY - You could try disassembling the unit and drying it off VERY VERY carefully - first by hand and then leaving it (stll disassembled) in a warm place - like an airing cupboard for a couple of days. Then put it all back together again, and power up.

In the case of sticky drinks, like lagers, coke cola, etc... you may want to disassembe the unit and actually wipe the board with a water-dampened cloth - but again make sure its given a couple of days in the airing cupboard to dry off 110% before attempting a power up.

At best, you've lost an internal fuse, at worst, you'll need new components, PCB, power supplies etc..etc..etc...

Thanks Gary
Just what I thought
I did wonder whether he could open it up and dilute the wine with some water before it eats into the boards but it is a very tricky thing
As you say maybe it has just taken a fuse out

The other thing to watch for with "water ingress" or in this case "alcohol ingress" is that not everything inside is waterproof, even without power.

EG: Insulating tape stopping spark jumps, stickers which might be covering "UV" windows in EEPROM chips, warranty stickers etc...

If, once opened, a loose piece of insulating tape is found "drifting around" its worth making a very detailed search to find out where it came from.

If it was powered up at the time then it is highly likely that you've got some extensive damage. PSU's are the least likely to fail surprisingly. In modern equipment which uses closely packed surface mount components spilling liquid over "live" components is the equivalent of shorting all of the legs of each component together. Which basically means you run the risk of power going down the tracks of audio circuits .

If its limited to one pcb or area then you may be lucky and get away with having a few components on the faulty PCB replaced, more than likely the Op-Amps will need looking at.

Of course, you can try and salvage or "clean up" the inside of the mixer, you've got nothing to lose by trying and you could get lucky. Use Isopropyl Alcohol to remove the sticky residue from the PCB(s), pay particular attention to cleaning between the legs of the I.C's and components including edge connectors and bus connectors. ( Take time over this since Even if the mixer works immediately, the slightest bit of conductivity can cause shorts and crackles or poor audio in the weeks to come). Squirt switch cleaner into switches and faders, although if any faders have been contaminated then consider having them replaced, since they are very difficult to clean internally.

If he has insurance consider telling him to make a claim, it's likely that if the internal components have been seriously damaged that a dealer would term it "Beyond economic repair" in any case!.

Hi Guys
Update on Dynacord clean dried out appears to be working at the moment
Hopefully will be ok
Thanks for your advice Chris/Gary
