My receiver still turns on and I can here a faint sound if I turn the volume way up. It was working fine until a day when there was some very brief power dips due to whether or folks working on the lines. Is it a blown fuse and where? Or something to do with the amplification? Is it worth taking to be serviced or cheaper to get something new? (At over 5 years old it's well past any warranty.) Or could I learn to find and fix the blown part with pluck and skill?
Thanks for any advice.

Re: Blown something? No amplification?
If you hear a faint sound I doubt if a fuse is blown?? never Know though. You have to have and know how to use a DVM or muti-meter to trouble shoot solid state electronics, as well as know how to solder and check transistors and other electronic parts. There wouldnt be one particular thing that could cause your problem. There could be a several things wrong as transistors and ICs tend to snowball and short out or open up with power surges. If you want , first get a schematic, but if you dont know how to read one stop right here and save your money and upgrade to a shiney new stereo system.. Good Luck

At this point, I would just take it to a tech rather than poke around in it. It sounds like the power section is the problem as you have guessed, but without the technical knowledge you'd be shooting in the dark. That particular amp is right on the line of being expensive enough that would be worth repairing, but you might do just as wel to check Ebay for another used one.
Are the speakers selected for A or B or AB check the speakers by using a 1.5 volt batter on the cable going to the speakers, if you get a sound from the speaker, you know they are ok, if not, speakers are faulty.
NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. Turn the volume control to something medium. The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.
Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.
There is a good chance that a common control may have developed a high-resistance or 'dead
its more than that i think you have either turned your speakers a/b off or have blown up the sound valve i would send it in for checking by a ppro as no adjustment would be needed to get at least some sound
I have just brought a vw passat with the CM 168 in it and the screen is very faint,you can see it but its not bright at all,is there something you can do to brighten this.also wwhen I try turning down the volume,the volume is sensative and goes up and down wwhen you are turning it and eventually it goes up instead of down,they only way to adjust the volume is to use the remote.so when you turn the dial to left to turn down,the volume will go down in numbers like its going down and then start to rise in volume the more you turn the dial left.please let me know what I can do, Cheers Shane
most higher end integra's have a input level adjusment or input selection for each and every input. Perhaps you are not on the correct input, go to onscreen programming and check out the input level and input select - also try the tape in another input like tape 2 or cd. It will not hurt the receiver for a test. Also, if you are using the cheap cables from the manufacturer - try a pair of cables that you know work or go by some. BTW, you don't need to spend $40 for cables order them online through amazon or other store. Gold / sliver plated oxygen free are best.
could have blown the speakers or if there sub woofers ran off an amp that might be your problem as far as the cause it could be something as simple as a loose ground or some wire that is getting power grounding out on a piece of metal somewhere i would double check all of your connections
I get the same problem with my Nakamichi, but it never bothered me much, since i can't notice any quality drop, besides, its only radio. I remember it happens only on certain stations though, which leads me to believe it might have to do with the broadcast itself which oscillates and varies in amplification from station to station, and is affected by weather and geography.
If it really botheres you, try getting extra juice amp for your tuner from some specialy electronic store.
