Re: Denon AVC1530 Amplifier Protection mode
Protection means that the output stage of the amp has detected a problem. Usually this is because there is DC present on the speaker line indicating blown outputs. Figure on $25-$45 for parts plus the local labor rate for the repair.

That model shouldnt be stuck in stand-by
Are all the speakers connected?
If it wont properly turn on then there is a fault being detected. Could be disconnected speakers / bad speaker or a power supply issue
if ur output power amp is defective u will have that problem - meaning the moment u connect load across it it will go into circuit protection to limit/stop excessive output current. make sure the speaker terminals are connected to +/- output terminals. in bridge mode use only channel 1 and that too with 4 ohms speaker only otherwise amp will clip. considering all connections are okay if it still clips when speaker is connected, u have a faulty power amp section. this the way ur amp is designed
are you playing a cd which you recorded at a higher level? if so, you are overdriving the amp. you may want to check some of the setup menu items which could contribute to this. it also could be caused by a driver or component in a speaker which is getting maxxed out, which is easier to do with the cd source than any other in some cases. denon protection circuits are quite sensitive. good luck
disconnect speakers at the amp, turn unit on, if it goes into protect, it needs service. If it stays on, re-connect speaker wires without speakers attatched at the other side and test again. (make sure wires are separated and not touching metal!) if it stays on still, check speakers one by one, when it goes into protection, you have found your problem. Disconnect the bad speaker and test again. Process of elimination. It can only be one of three things. Internal amp problem(nothing connected and protection) wires(no speakers connected and protection) or speaker(s) (when speaker connected,protection) Hope this helps. If you need deeper troubleshooting with this issue, post a comment and I can help you further.
The numbers of the transistors thay you need to replaced are on the transistor themselfs. Just take out the bad transistors and get the numbers that you need. I ALWAYS replace the output, driver and bias control transistor myself. One thing to keep in mind, if the number on the transistor starts with "A or B or C or D or K" you need to add "2S" in front of that number when you order it. Now that this problem has repeated itself, double check your wire and speaker. They can cause this problem.
protection mode activated to protect your amp from a problem. please disconnect all your speaker from the amp and check if it is fine start to connect your speaker one by one until you find the bad one which make the problem-change its cable first and then speaker itself.if the problem still you will have a problem in amp.
Make shure your speaker wiring is solid hookup to amp and spekers (NO CROSSED WIRING). Also make shure speakers are not wired in parallel or the speaker impeadance will be to low and amp will kick out.Turn speakers off then hook up headphones and crank up volume then see if amp kicks out.If it does you have an internal overload and needs serviced. If it playes ok then you must have speaker problems or wiring.
yes,pls.stop plugging the system,you may harm your system if you do so,the system has it's own system analysis mode,and if there's something wrong in the circuitry,it will activate,you need the authorize service center my friend,it's a technical problem.
