I have had no problems with this receiver for 7 years. It recently began not operating upon initial power up (It powers on but no output via speakers). I can only get it to work by cycling through some of the various inputs (this does not always work). I do not know if it is some relay having to do with the various inputs or if has something to do with the length of time the unit has been powered on.
Any help would be appreciated.
the reason of mute command from CPU is fault command from DSP sendin via pin ABOOT/INT. i resolderin Q708,Q709,Q710 pins - solution#1 from Luisa_K and receiver work O.K.the reason of mute command from CPU is fault command from DSP sendin via pin ABOOT/INT.

It seems that one (or both) of the power amps are defective. To have a quick check, take a meter, sett it on the DC voltage and measure the outputs, one by one (with no speaker attached and no signal) for the short time when the unit stays on. If you have high DC voltage on the outputs (one or both) this means that channel(s) needs repairs (most likely the power transistors are blown). If one of the paired transistors is gone you need to replace both of them anyway. Good lock Kostiko
you may have some thing like a "spider" shorting out the power inside the motor maybe,,,but one thing is certain you do have a short in it some were if its popping trips out
Just a further note..
Before you replace the fuses, (be sure to get an identical replacement, wouldn't want to start a fire), so you remember how long ago you began to have this problem, and, if you can recall anything that might have caused it?
Hi,
Yours might be a case of a batch of factory defect batteries. Bring it back to Circuit City and ask for a replacement but ask if you can get from a different batch. If they will not agree, show them the problem and try it in their presence. Though you may also ask for a check up of the output of the adapter and its charging/powering capacity.
Another thing you can try is to power up then shutdown your laptop normally (even if have to use AC). With the PC off let the AC adapter focus on charging the battery for a couple of hours at least (overnight preferably).
Then try again using the PC battery only. If this does not work guess your back to Circuit City.
Good luck and kind regards.
Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
This maybe an easy one. Have you unhooked all the wires going in to the stereo. "SP wires" means you have wires to the speakers are touching and the stereo is shutting down to avoid overloading. Hope this helps...
The control panel may in *LOCKED* mode.
Press the *OPTIONS* and *SELECT* buttons at the same time and hold for about three seconds to unlock the control panel.
Make sure the detergent tray is fully closed too.
Its one of Three problems. The main b+ filter is defective, one of the standby power sources have a bad capacitor on the line, or theres a short in the main amp. section. Its probabvly going to cost you more then you would care to invest in a reciver thats around 5 to 6 years old. Its most likly time for you to upgrade to a suround sound dydtem with new fancy lights bells and whistles. Good Luck
