SOURCE: samsung tv stoped working, it now wont power on, the red standby light dosent come on.

Yup I would tend to agree it's probably the PSU... It shouldn't be too expensive to fix, probably an hour or so labour and either parts OR a complete new PSU, in saying that ensure ya take it to a reputable service place.. and get a "quote" B4 allowing to continue.

SOURCE: Stopped working

I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

If you followed the instructions correctly, then the amp must be defective. This is sort of simple.

My generic suggestions:
You have the power, the ground, the outputs to the speakers, and then the input.

Make sure that none of the speaker wires are somehow being grounded. Make sure that nothing is shorted that feeds the speakers.

Not very likely that you can fix it yourself with little electronic skills. You fried the channel you had it connected to. It will require the replacement of a lot of parts in the amplifer circuit. When a channel blows it has several transistors, several resistors, sometimes a couple of diodes and capacitors, and sometimes with the sony amplifers a pre-amp driver IC that will need to be replaced. You will require a multi-meter to determain which parts must be replaced, a soldering iron, some solder, and some solder wick to remove the solder from any bad components that must be replaced.

Any time you connect more than 1 speaker to a channel you risk over-heating that channel and shorting out some components. There are no amplifiers that are designed for more than 1 speaker per channel. I have repaired many sony recievers, including the one you have on several occasions, in the 18 years of working as an audio repair technician. With 2 speakers on the same channel you will draw double the amount of current thru the amp circuit than it was designed for. With 3 speakers on the same channel you will draw triple the amount of current and so on, and so on. I am really surprised that it played for more than just a few seconds with that many speakers on one channel. It must have been in really great shape to start with. I am sorry you did not know this before your party, it would have saved you some money.

Now the good news!

It should be able to be repaired. If all the speakers you had connected were really all on just one channel, you should have only one channel bad. This is a nice receiver as I am sure you must know, since you own it. It is worth getting repaired. As I have stated, I fix these for a living and I would expect the repair cost to be around $125 to $150 if it was taken to the service center that I work at. I can not be certain what another shop would charge, but this is a pretty good estimate considering I do not have it right in front of me to troubleshoot. Some shops are more honest than others, and there is always the chance that there may be more damage than what I would anticipate, or even less damage than I would expect resulting in a cheaper repair.

If you want to take a crack at fixing it yourself I would be happy to guide you thru it, but you would need the proper tools as I stated above.

I hope that you have found this information helpful, and if so, a rating of "FixYa!" would be appropriate and very much appreciated. After all, it is the only reward we get for offering people like yourself this free information and help.

Let me know if you want to try and fix it yourself, or if you have any other questions I can help you with.

You are overloading your amp. IMO 640A cannot handle heavy loads.

Better change the speaker combo and connect something that puts right load on the 640A. Else, get a meaty amp from CA.

Just make certain that the connections are all good with no wires touching. If it still doesn't perform after that return it to where you bought it and get a new replacement or your money back.

Cambridge azur amp 640a working brill till yesterday !! now protection light !!!! turned it off numerous time etc plenty of venterlation carnt get it to work


Looks like the fuse blown.. or the classic symptom of electrical fault inside the amp. 640A uses a sensitive protection circuit often ends up in this irritating situation. Normally, there is nothing much you can do, but just check your wall plug connection for Open Ground or Left & Neutral reversed issues. If the wall plug is free of error, then you should better contact CA technical support.

Hello, I am trying to plug my Mixer into my amp but only one speaker has sound..I am using a Rane ttm57sl mixer with technics turntables & cambridge audio azur 640a amp...I've gone from the Aux out on...


Why don't you try using the main outputs (the 2 XLR connectors). With 2 cables connect these two (left - right) outputs at your amplifier's aux in. In that case take care that the "output level" of the mixer works like master volume controlfor the signal that the mixer sends to the amplifier.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Connection of ipod touch with Cambridge Audio 840A


Get a 2.5 mm stereo cable to dual RCA ( phono plugs)
Radio shack or Walmart will have them.
Connect it to the aux or CD input in the rear of the amp.

My amp


Yup, looks like someone who does not understand the quality of a Cambridge amp connected it wrongly, or with mismatched components. Since you state that the Amp was very hot,It suggests that the Speakers hooked to the Amp were of a Higher Rating than what the Amp could Handle. That it worked for about an hour is credit to your machine. In all likely hood. 1. The Power supply fuses are blown, and 2. The Audio Aoutput Transistors also. can be fixed, but very expensive job, and only in the hands of the right Technician.
