powersoft k10 no sound/dsp error

i bought 2 broken k10's

1 had a the left channel that didn't work and a screen that was only lid.

switching the front panel solved the problem, channel was on mute.

contacts where heavely corroded en components where falling of.

that i cannot fix so thats being repaired by a professional.

now the next amp has everything working but started with a 'sharc error'

that was solved with armonia, after connecting the firmware was updated and the error was gone.

al the settings where set on factory settings.

my hands where itching to test my recently bought 13x mach ms118 cabs.\

so i hooked 8 of them to the amp, the bottom led's lid up after applying signal and bass came out.

then the bass stopped, whent back on for 3 min, then off.....take an other xlr cable to rule that out.

when the bass stopped the bottom leds where out, so no signal present, checkt the xta en yes it's giving signal.

took the amp inside for a closer look, discharged the capaciters en started checking.

after my experience with the first amp i checked the front panel for corrosion(ok).

took the amp board out and checked the link/stereo switch (ok).

checked the bandkabels(ok).took the dsp board out to clean the contacts but they looked in perfect condition.

put everythinh back together and hooked it back on my laptop,connecting was nog problem, all the basic settings and data was in real live and worked, dsp settings opend for a brief moment and then it flipt to (initalizing) en after a min it flipped over to a workspace that worked??opened somethin en that it when't back to (initializing connection)

i put in a xlr bluetooth audio device and when the dsp is working the bottom led's lid up.

they go out when it's(initializing connection)

i'm thinking powersuply, bad contact?something like that.

does this familiar to somebody??

indeed corroded, the one just under the red connector is also a bit corroded.

i will have them replaced! thank for your tip!! much apreciated!!

I have the same problem.

Does anyone know or has a board they could measure or a circuit diagram ???

this helps diy people a lot!

Mine is stil at the repair shop, so will get back to you when it's back.

al the problems are solved, dsp works perfect and the screen of the other is also working.

cleaned both amps,  washed the filters and replaced the led's that where broken.

also took the powersuply connector out en made a permanent cable connection.

thanks all for the help!!!
