Are you an experienced tech? In most cases (unless there is a defect in manufacturing) transformers are not a common cause for failure. If it blows the fuse disconnect the secondaries and see if it still blows the fuse. If it does then the transformer is likely the cause, if the fuse doesn't blow then the problem is elsewhere. If you have 120vac at the primary and nothing(or very low) at the secondary(s) then the transformer could also be at fault. If you have done this already and narrowed it down to the transformer, sorry I cannot help. I used service Samson but no longer am able to get parts. Good luck!

Is the input cable okay on othe systems? Is the voltage switch setting correct for yourpart of the world? Is the GND/LIFT switch fully set to one side or the other?

If you are plugged into the 1/4 ich jack- is you plug the correct length? There are 5 different lengths on thses.

It also would not hurt to spray some LPS-1 into the controls and switches and cycle them to clean contacts as well. And into the 1/4 inch jack directing the spray towards the interrupt contacts.

hi, my samson xm610 have a problem even i tern off the voluem of each chanel still have a sounds be fore is not just like that.. can you help me

Have you checked the cables? If that doesn't fix it, you probably have a loose connection inside between the "mixer" unit and "amp" unit

Ok. First, check your power supply voltages....then check IC2 for correct voltages and also check C9 ,C17 for ESR...clip signal can come from either woofer or horn circuits...lift one end of R19 in the preamp ckt....this will break the woofer signal and see if the light goes out...if it does, look for issues with the pre-amp after it seperates the hi and low signals...if not, then look for problens in the horn circutry.....and get a schematic....it will make it so much easier....good luck....

This is likely a power supply failure within the unit. Needs to go to a shop for repair.

if its not right next to where the AC power plugs in, or part of the power plug itself ( lil notch in cable recepticle that will allow it to slide out ) then it would have to be inside the mixer on the power pcb. ( the board the power cable connector is soldered to)

Use INSERT cables to insert into the MAIN's. This will compress the whole level going to the mains.

"Tested with other speaker and cable" ... you did not tell us the results of the test. If swapping the speakers and cablles still had the same dead side, it is probably the power amp for that side and not the mixer part. Take in for repair. If you had an accident of speaker cable not being plugged in fully or pulled out while operating, this pops the power amp real quick. They also just plain fail at times. Plug a set of headphones into the MONO out jack. If you can hear audio going through the unit then the mixer is OK... and the power amp on the failing side has a failure. Note the headphones will be low level and probably only one side, usually the left as this is a mono signal and headphones are normally stereo.
