Does the display show you are in protect mode , or is a light indicating that? The unit automatically switches to standby when the
"Hardware" - "Power Management" - "Auto Standby"
setting in the Setup menu functions are set. The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.
• The protective circuit function may have been activated
because the temperature of the unit rose abnormally.
If this happens, then the power will continue to turn off
after you have turned the unit on again. Make sure the
unit has plenty of space for ventilation around it, wait for
the unit to cool down sufficiently, and then try turning it
on again. This is out of your users manual.
General suggestions are to remove all speakers and speaker wiring with unit off. Turn on and see if problem has stopped. If not, let unit cool down if warm and try again later. If problem is still there it needs repair shop work. I fht problem went away, shut off power and connect one speaker at a time and testing. Keep adding speakers one at a time with power off and see if a bad speaker or wire set can be located
Do you hear the speaker protection relay click after about 10 seconds when you turn the receiver on? Does the display show PROTECTION on the display? These conditions indicate a bad channel that will keep the receiver from functioning but you still have lights. Steve
Hello Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service. Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display. Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.
Hello Protection display will come over this type of set, when it is overloaded or system confused condition. Just unplug the device from AC mains socket and replug it after 4 to 5 minutes, and see whether it shows any protect display. If it shows it again, just disconnect the output loads, ie, connected speakers, and check. Again it displays 'protect', the internal circuit, especially the output amplifier circuits has the trouble, and the system need service. if it does not show protect display, after disconnecting the speakers from it, check the speakers or its connecting wires for damage. OK.
If, after four (4) minutes the pressure switch still senses foam in the wash tub, the Central Control Unit will go into Failure Mode. The digital display will show, F02. Cause: wrong detergent, too much of the right detergent, detergent placed in wrong compartment.
xp:
1. right click on unused space on your desktop and click properties to bring the display properties, (you can also go into start>control panel and double click on display)
2.then go to the screen saver tab and click on it
3. modify the time for screen saver to come up and uncheck the box that says "on resume password protect" so you're not asked for a password everytime your screen saver is on and you're returning to work on your computer.
vista:
it's a bit different than xp but similiar in some sense..
when you right click on the desktop go to "Personalize" to bring the display properties and then go to screen saver and modify the wait time and password protected settings.
push power protect is error signal shows problem in power amplifier board, mostly power amp out
IC STK402-100S found deceptive.
contact nearest Sony service center for proper repair.
Take every single cable out of the unit, now power on the unit.
If the power protection still shows then there is an internal fault, usually a short or a component defect.
If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.
Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.
