Disconnected system for moving furniture.....when reconnected no sound whatever,,checked all speaker wires OK. rolling panel powers and cd,s rotate,everything powered alright but nothing from speakers.Are there any fuses inside the main componenent box?
Hi there, I realised that with my MX-J900, if clock has reset to '0.00' after being unplugged, it will initially show the demo mode, then once switched on it will work as normal, but once switched-off to stand-by it will not respond to power button if the clock wasn't set to the correct time. To fix this; simply unplug from power for a few minutes, plug-in, then switch-on at demo, set clock & unit should work as it should! Cheer, Stevie-Ray ;)
When you switch the unit on make sure that you hear two clicks, this will tell you whether the protection relay is working. Should you hear the two clicks this will indicate that the audio ic`s are working. There are fuses inside the main component box, four on the transformer. Let me know the outcome
Hi Guys I Have Just About take My Jvc mx-j900 totaly apart and i have only foun the three fuses on the transformer can anyone tell me where the rest are.

Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.
First disconnect the CD head unit from the sub amp and see if the other amp works. If yes, the problem is the wires to the amp, the amp itself, or the subs/sub wiring. If no, the problem is the head unit--probably an internal short. If the other amp works with the sub amp disconnected, reconnect the sub amp to the head unit, but disconnect the sub wires from the amp. Try the CD player. If the amp goes to protect with no speaker wires attached, the amp is bad. If the amp is OK, the problem is the subs or sub wires. Hook the wires up to the amp again, but disconnect them from the speakers. Try the player again. If the amp goes to protect, the problem is the amp wiring. If not, the problem is the subs. Check the impedance of each sub using an ohmmeter to determine which amp is out of spec. Please let me know if you have questions, and thanks for using Fixya.
It's in protection. Disconnect all your speaker wires at the receiver then power it up. If it stays on, the receiver is ok and you need to check all wires and speakers for shorts. The easiest way is to reconnect one speaker at a time and test power until it shuts down, then disconnect the speaker wire at the speaker and test again. If it stays on, meter the speaker for shorts or bad voice coil. if it still shuts off, check your wire or replace. If the receiver's power still flashes with all speakers disconnected, it needs service or replaced. Before reconnecting your receiver after repair or replacement, check all wires and speakers 90% of the time, that's the cause. Hope this helps. If you still need help, post a comment and I can help you troubleshoot further.
You have a speaker short. Disconnect all speaker wires at the receiver, then turn it back on to test. If you don't get the error code, your receiver is still ok. Reconnect your speaker wires one by one and test the power on the receiver until you find the wire that's causing the problem. Then disconnect that wire at the speaker and test again, this will determine if you have a bad wire or a bad speaker. If the receiver still reads error without speakers attatched, you will need to send it for service. While it's at service, check all wires and speakers for shorts with a meter if you can. This is the most common failure of all receivers, a shorted wire. Hope this helps
Make sure you have the right speaker wire (green plug to green socket) You should have three wires going into the right speaker, the left speaker, sub woofer, and the power wire...and one wire coming out as mentioned above. double click on the speaker (lower right corner of the monitor) and make sure the volume levels are normal. And too check the volume level on the right hand speaker. hope this does it for you, PLease leave rating...thank you
please reconnect your system again and confirm that cd cables in cd in in your receiver and try with another cables- and check another input if your system is ok the problem will be in the the cd itself or its cables-if not tle problem will be in receiver or its speaker cables(check that the wire of the cables does not touch each other)
PLUG IN YOUR HEAD PHONES IN - do you get sound ?
If you do Get sound from your headphones it could be that your speakers blown and would recommend Bose to take a look if still under worrentee.
if NOT You could still get it covered by domestic general
find them at this link
otherwise if you dont want to pay for a repair take a look yourself - get a screw driver open up the case as best as you can look at the speakers, you may well find that you have a dry joint or a cable could have come disconnected if so solder it back on and you've FIXED IT!
hope this helps.
if it does OR IT DON'T, please leave feedback Anyway
