Nakamichi AV10. Re: left channel softer than the right one.
When i turn the volume knob just a little, i can hear sound coming from the right speaker but not the left one. When i turn the volume louder it seems that the right channel is louder than the left one especially the treble is obviously lack off. Because of this it has affected the stereo imaging during 2 channel listening as well the HT surround effect.

the knob that turns the radio on and off is the volume potentiaometer.turn it 1/2 wayopen.the next knob is the squelch maqke sure it is all the to the left.the next knob is the mic gain and the RF gain.Set the mic gain at 1/2 and the RF gain all the to the right.the next knob is the delta tune,set it 1/2 way the next knob is the calibration knob leave it alone.Now above those knobs are little switches .the third switch from the left is for CB/PA make sure its on CB. check the WX switch and make sure it not on a weather station. and finally the last switch to the right is called a dynamic squelch switch.Make sure it is down. with all said your radio should be on and you should be able to hear sound. If not ,take an external speaker and hook it to the external speaker plug in the back of the radio.If you hear something then you internal speaker is junk.replace it .
Turn the radio on, turn the squelch knob all the way to the left,turn volume up, flip the switch to cb,not to pa,turn rf gain to the left,flip switch to normal,turn channel to 19,make sure the antenna is connected and mike is plugged in,can you hear any talking? If not let me know for further information. hope this was very helpful..
My Pioneer VSX-36TX (circa 2002) does the same thing. Modern AVR's count up from minus something to 0db and go just a few db higher into 'plus' territory. It seems arbitrary but that's how it is.
Ask yourself this: who ever really turned the volume knob up to maximum on any amp on purpose, and had speakers survive it? In other words, why have all that capacity on a potentiometer if you never use it?
Little known fact: With that in mind, Bose Corp actually designed a product that intentionally used the full physical travel of a volume control - the Bose Acoustic Wave Music System.
Good day sir, Hi, your Philips receiver trouble can be any of the ff:
your receiver left fuse is blown, check if it has a user fuse at the back. or
your main IC amplifier for the left channel is bad. you need to replace that IC, but check first the wiring of the speakers.
Check your receiver left speakers if it is producing a soft hum, to do this turn down the right channel, or adjusting the balance knob to the left, or simply remove the speaker connection of the right channel. place your ears on the left speaker as you adjust the volume up and down, do you hear a soft hum that goes up and down also? If yes the problem is on the source section before main amplification, usually the pre-amplifier stage, If you hear no hum at all. problem with the main left amplifier. The main amplifier is usually a single IC for both left and right channel, OR one IC amplifier for the left and one for the right, in both cases, replace the bad IC.
could be the speaker, try connecting another speaker and cable and see if it improves. If the problem is still there and you've checked all the settings insuring that its not turned down, then could be an internal problem with the receiver.
Hope this helps a little at least.
