My Samson Auro D415 peak light stays on, and i get no sound when powered on
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....

won;t power up
Try changing out the Pico fuse. Only 50cents from online West Florida Components. Buy a few. Mine went out twice. It is Item # F021. It is a .5amp (500 mA)fuse-green and looks like a resistor. Location on the circuit board is near the transformer and on back edge or board behind the 2 brown wires connecting to the board and to the side of the 4 diodes there. I left the bad fuse in place and soldered the new fuse to it's legs-a lot easier and does not damage the PCB.

Fix f on a psr 740 yamaha keyboard
If it is just the one note that has stopped working it is probably the contact strip.
you could check this by moving one of the contacts from a working octave to the non working octave, if it solves the problem just replace the contact strip.
report back if this solves the issue and I can point you in the right direction for the part needed.
