hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

I set the volume to 40. After a little while the volume starts dropping down. If you do not turn the volume back up the volume will eventually go to zero all by it self and turn off the system.

The volume gets noisy, cracking sounds and fades out


Your volume control is dirty. Apply some deoxit or wd40 directly onto the module.

Raised volume cuts sound and gives me "overload" message


A couple of possibilities: Bad solder on power regulators (attached to main heat sink) or cooling fan may not be turning on when volume is raised.

Crate BT50 Bass amp cutting out with high input.


Sometimes an amplifier's preamp can't handle certain signals/frequencies at a high gain, so they cut out. Bass guitars are especially prone to giving such a strong signal.
I bought an older, nonworking bass amp recently and fixed it just to find it had the same problem. Best solution is to put a low ohm resistor at the amps input, but if you turn your guitar down to half volume it'll have the same effect: should prevent it from cutting out.

Sound Cutting Out


We also had this same problem, make sure all speaker wires are correctly connected and have no breaks as any wire problems will cause amplifier to cut out. The system works fine now and also plays from the pc without any cut off. Hope this helps.

Technics receiver SA AX540 overheating


is the fan turning on? many models like these have a cooling system (fan) that kicks up when the volume is turned to a certain level. if your fan has never been on, then chances are some of your soldering points have shifted or gotten a little messed up over time from the heating/cooling effect. this model runs extremely hot especially right where the vent is on the top of the cabinet. make sure that it is not in a shelf or enclosed area. dont stack other items on top of it. use an external device to control the volume so that you can have the receiver volume at a fixed level where the fan will turn on. if your sound still doesnt work, you should consider buying a new receiver or try your local craigslists forum. make sure if you buy a new one, that it is a more expensive model from a brand like sony and check the model online for known problems. stores like best buy offer extended warranties on most of their products which are very wise investments. good luck sinbad
