That depends on what has happened.
Begin by checking that the cables and leads are all attached correctly. It may be a simple loose joint.

If this is a separates system where the amplifier is a separate unit from the other devices, then makes sure that the correct component is selected (if there is a physical switch).

When you are satisfied that the amplifier is definitely not producing sound, then it is likely to need repair. Depending on the repair shop, you might be charged a lot of money. If your amp is still under warranty, take it to the dealer from where you bought it.

It will also depend on the initial cause of the problem. If something was connected to the amplifier that was not recommended, the front end may have to be replaced. That's a term to describe the delicate pre-amplifier circuits.

If non-compatible speakers were used, these may have had an effect if their impedance is not matched to the amplifier.

And if the volume (gain) was increased to 'see how loud it goes' then this may have damaged the output stage amplifiers.

My sound keeps going off .so i have to swith off and on again


It can be the power amplifiers may be over heating and cut out. Try hooking up the powered PC speakers to the AUDIO line out of the TV to see if the sound cuts out there also, if it does cut out then the problem is in sound processor section which is part of the main board, expensive part. Try my suggestion and post back.

Expensive? Depends if the house burns down with it. Call the Fire Dept before the next time you turn it on. Kidding.

Only a qualified tech with an eyeball on the unit could answer the cost question. It sounds bad. Not only does the smoking component need to be identified but the cause of its demise might still exist.

Cooling Fan Not Working


There is a fan drive circuit in these that will control the fan speed depending upon the load on the amp. It sounds like this citcuit is defective, This unit should be sent in for service. Crown units are not the easiest to repair and I would not suggest it be attempted without prior experience. This should not be an expensive repair.

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Can you help me?


Sorry to tell you this, but that sounds like your amplifier's DSP or DSP power supply/control circuitry has failed. DSP stands for Digital Sound Processing - Source Direct bypasses all internal amplifier digital processing, which is why you have sound here. Unfortunately, you'll want to brace yourself for an expensive repair, because DSP components are difficult or impossible to troubleshoot for a servicer, though sometimes it is something simple and quick.

If it's under warrantee, obviously it'll be covered - if not, you may still consider contacting the manufacturer for repair. They're often less expensive than local servicers.

Sound cuts off


OK,  That means there's some kind of crazy fault in the temperature sensing circuits. I'm afraid you'll have to take it someplace and have it looked at for a more thorough diagnosis.
