When dealing with stereo amps you should treat them as two mono amps joined together. So if one channel is dead you can compare the good channel with it. For example if you prod around with a small insulated screwdriver, each channel will buzz, so if the left side is down if it buzzers in the right at one point it should do the same in the other channel in the same place. Just be careful not to short anything out with the screwdriver. Keep away from the power supply as that is common to both channels and so can't effect just one. You can also compare the voltages for each channel. And if you see something burnt in one channel and not in the good channel you know something is up.

One channel missing at switch on. Can be recovered by switch off, or A/B switch

Could be caused by a dirty or faulty switch. Perhaps even a bad soldering joint? Servisol Switch Cleaner sprayed on might cure it. Make certain you use the one that is safe on plastics.
The fact that the channel is still present is a good thing. It's just something not connecting right.

Developed a hiss crackle and pop on the right and channel [ analogue connected] This is present when the cd player is just switched on but no cd is playing. If a turn the volume up on my amp the noise...

What happens if you select the CD but have NO CD player connected? It could be garbage leaking in through a signal cable.

Or it might be a flaky switch contact somewhere in the signal path on your amp. Typically, it might be a switch you rarely use, like a Tape Monitor or Mute. It's wise to occasionally (with power OFF) manipulate all manual controls throughput their ranges a number of times to wipe oxides from their contacts.

I have a Cambridge audio turntable which looses sound quality about halfway through record, as though it looses one of the channels (on the right hand side). I've tested the speakers, the amp, even had it...

Might be a weak relay or transistor in that channel, they both will stop and reset when overheated. make sure you're ready to test it when it does this again, this may help you locate the bad component. I'm leaning towards the transitor, because they also amplify sound signals in radio frequency.

The left channel in my Cambridge Azur 640 amplifier keeps cutting out. Wierdly I can often 'shock' it back to life by quickly turning up the volume a lot. Any ideas?

have the volume control cleaned by a spray of electronic contact cleaner. If the carbon coating material is already wiped-out due to use, have the part replaced

Cambridge A5 Amp, only one speaker works when phono selected

If both speakers work okay on other inputs .Then cable from pre-amp to amp and main amp are okay. If phone RCA jacks go directly to electronics board .Then its possible solder on phono jacks need to be resoldered or other connections in that section.If unit needs repair you can also purchase a phono preamp from radioshack hook up your and use it on other good inputs such as CD etc..Please note PHONO inputs are only for turntables .If a non turntable input such as CD,TAPE,TV Etc is used on PHONE .Then you will overdrive this input .

I am Having problem restoring my dell 2400

Well you may have a bad mother board or IDE port to which the HDD is connected. If the CD is connected to the same IDE channel as the HDD, move it to IDE1 which is the second IDE channel. If it then recognizes your CD, IDE0 is bad and you need to replace your board. Let me know how things are connected inside the computer.

Cambridge 540A something blew up when connecting input to amp!

mmmm... i had a problem like this before, it seems that you have blown a IC or 2 or 3... if you have blown all your channels IC's then it would be better to buy a new amp, it also depends on what watts your amp is... if it isn't a very high watt amp then it wouldn't be that much to fix, if u only blown 1 or 2 Ic in a channel then let it get fixed, and NEVER switch ports if your amp is still running/playing... its like fixing your car when the motor is running...
