I have a Sony X-Plod amp 760w 2/1 channel xm-1902gx. Everything is connected properly and the amp contains 4 lights (power,over current and two others). Power lights up like it's supposed but the over current lights up as well. I am unable to get any sound from it. Can you help me before I trash the amp.

Why does my Audiolab 8000s mute light stay on?


Your amp is probably in Protect Mode, meaning you have DC Offset( a damaged amplifier). That will have to be repaired, before you can switch the unit on. If you need more assistance, or would like to inquire about repairing it, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

Red power/protector light


The amplifier has gone into protect mode and will stay in that mode until the cause is corrected.

My Harmon kardon is stuck in protect mode


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

My protection light is green but i get know sound.


If no channels are heard, it might not be the power amp section to blame, in any case the protect mode would only activate if an overload was present, caused by faulty speakers or wiring often!
Having said that the power amp could be to blame, but only if the amp used a single IC to output stereo channels.
Apart from that what you are looking for is something that is common to both channels, perhaps a pre-amp IC?
Hope that narrows the culprit down for you.

After playing for a while my Sony Surround Amp cuts off and shows a PROTECT Reading in the window.


Sounds like the amp is protecting itself from an over-current situation.
This happens when the machine has to try too hard to get sound out to the speakers.
There are several possible reasons.
You may be using the wrong impedance speakers for the amp.
-some amps only work with 8ohm speakers
-some only work with 4ohm speakers
If you have a short circuit in the speakers or in the speaker wiring, that could cause the amp to overwork and go into protection.
If you connect up multiple speakers to the same single output of the amp you effectively short out the amp and cause it to overwork also.
Before troubleshooting, blow out the amp, dust inside can cause lots of problems with the electrical systems. Use canned air and do it outside with fresh air.
To troubleshoot :
1. check to see that the amp and the speaker have the same impedance number, either 4 or 8ohm. This is usually printed on the back of both. If they do match go to step two.

2-unplug all the speakers, add one speaker(left one) and test it for awhile to see if it goes into a protection mode. Next move that same speaker to the right side output and run it for awhile to see if it goes into protection mode. Repeat the test with your other speaker, moving it to both outputs(L&R) to check if it works. If the amp fails with either speaker on either output, you may have a mismatch of speaker and amp or a bad amp. If you have only one speaker that causes a protection, then you have a bad speaker or it's wire. If both speakers go into protection, get different speakers and test again. if it works for all of these tests, go to step three.

3.hook up both the left and the right speakers to the amp. be sure that the wires are stripped cleanly and twisted tightly, if you have screw on outputs that is. Test for proper operation. At this point you should know if there is a single speaker causing the protection or if it is a amp malfunction.

My Sony XMGTR2022 goes into protect mode at


I discovered that there is a compatiblilty problem between the Bose receiver and the Sony amplifier. If I disconnect the receiver from the amp then the amp starts up normally. Apparently the receiver sends out a dc offset or a "thump" that the amplifier doesn't like and goes into protection mode. I solved the problem by putting a 1 second delay circuit between the receiver startup and the amplifier startup. A simple RC delay on the remote input to the amplifier solved the problem.

Protection lite and over current lite stay on


Sounds like a problem with the coils. Coils are known to short-out during periods of high-use. This happens when the insulation between wires break down and allow for a path of lower resistance for the current to travel. If this is the problem, you'll have to replace the coils in the amp which is a weekend job, but completely do-able. Hope this helps

Marathon 2000 amp... PROT light


Ok this means the AMP is in protection mode!..most likely the cause is a short in your wireing from the speaker wires! check all wires going in and out of amp! Look for stray wires touching metal or other contacts! (If this does not fix it the short may be inside of amp!
(This has nothing to do with a fuse!)
Please rate this FREE response!
THANK YOU!

Long startup


There is a bad connection in the other channel or the speaker relay has a bad contact in it.
