Question about Audio & Video Receivers
Even if it were a fuse, a blown fuse is merely a symptom not the solution. From the symptoms you've described the AMPs are the most likely problem. They are mounted to a large aluminum heat sink usually about center of the main board. There are several and they are a task to remove and replace because the entire board has to be removed... However, it's not too costly a repair and for a qualified shop something that can be done in a couple of hours - including testing. If you like the receiver get it fixed. Compared to most digital receivers today it's probably cheaper to fix this one than buy another. And a good repair shop will add years more life to that unit... Hope this helps. Bill

The only fuse on you stero is for power it's a 6.3 amp 125 volt it'on the main board. I have the sam problem I found a resistor on the board that controls the power amps on the heat sink. A lab here charges 35 dollar bench charge and if you want them to fix it they will apply it to the job. I own the same model and i went to circuit city they had lot of different system on sell. So before i put that in to an old system i'll buy another one

Since you mention that there is no standby light at all, the problem could be related to the receiver's main power supply, which is not uncommon for a unit of this age.
Now, if you decide to take the unit to a repair shop, do not let the cost of repairing the unit be the only factor that determines if you bring it back to life or to use it as a door stop.
Consider the replacement cost compared to the repair cost, also, have in mind that newer receivers can supply more output power per channel and have more advanced decoding technologies among other features. Hope this helps your decision. Let me know.

SOURCE: reciever won't power up
HI, this amp may need to be reset. also, i would check the voltage selector on the back side to make sure the switch is set to 110-120v. once this is done, you will need to reset the microcomputer. here is the procedure.
The microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If
this happens, execute the following procedure to reset the
microcomputer and return the unit to its normal operating
Procedure- Unplug the power cord from the wall outlet, then
plug it back in while holding down the POWER key.
ok, after this reset, if your receiver isn't operational, it may have serious damage to its power board.

Might be over heating. Make sure you don't have anything sitting directly on top of it. I even put a little fan blowing outward at the back of my system to keep it cool.

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.
