Hello
Long time storage may have make electronic contacts to get poor and fungus infected. Your set need a whole service. During service they will clean all the contacts and rectify repairs if any. Get it serviced. OK.

Overload


Have you checked your wiring connections? Wires could possibly be touching each other making it short out and giving you that "Overload". If not that then I would say it could possibly be a fuse that has gone bad inside. ??? Just some suggestions. The reason I say that it could be the wiring is because when I hook up a system and the wires accidently touch each other it overloads the system past a certain volume. Again I would check my wires first and move on from there.

Have Kenwood CD UD-405 not used for many years. Will not now play CDs or sometimes a few tracks then cuts out stating *NO DISC". Seems fine electronically. Tried switched on for several days to remove...


Seemed to have solved problem by using lens cleaning disc. Had no effect at first but kept trying it and eventually started working. Many cut outs but kept repeating and eventually played without cut outs.

Akai s6000 sampler unused for most its life. Just when we need it it fails on the third full day. On power up the display is blank and all led buttong thats 8 under the screen stay fully lit. Power supply...


Same problem with an Akai S5000.
Display gets darker because power supply outputs for the mainboard starts falling after start up.
Don't know if its the mainboard is causing the problem or is a problem of the power supply itself.
A S5000 service manual will be helpful.
Best regards

There may be some missing voltages from the power supply or a circuit pulling it down. Needs to go to a shop that knows how to fix older equipment.

Unit going into protection mode


You should first have or check the impedance and resistance of the speakers. then if all the speakers and wiring checks good, the only way to tell if this unit is good or the output section has no problems, is to hook up load resistors to where the speakers go, insert 400 to 1000 hz @.775MV into an input, hook up an osilliscope to the load resistors and slowly turn up the volume and see if the waveform clips before it shuts down. I doubt if you will have the equipment to preform these test but a good repair shop will be able to help you out. If it does not clip or go out then its all speaker wiring and/or the speakers.

Static and crackling sounds


Sorry to burst your bubble my freind but things do wear out as you had plenty of life out of this unit.. Your problem is a transistor or a driver IC is breaking down under a load and heat and will get worse to where you wont be able to use the unit.. It will probable cost you in a range of 200 bucks or .more!as there is no quick fix for a solid state unit that has no user serviceable parts inside. Its just not replacing the bad part , its the hooking up to the load resistors then seeing that several other parts are not up par and having to start rebuilding the amp statges of your reciver.. If its more then 8 years old Time to landfill it and get a new one .. Put it to rest. It dosent owe you anything as its been loyal to you all these years!! Good Luck
