Re: left channel not working
Probably Broken solder connections in unit. I have seen these units have many poor broken connections throughout amp espcially around poweramp ic .IC701
I have a service manual if you are interested in it email@example.com

Check the speakers if they work. Connect the speaker terminals using a short wire to a 1.5 volt battery (AA or any dry cell batter) and listen if there's a thumping sound when the wires are connected to the battery terminals. If there's no sound, your speakers are busted. If there's a sound, check if the wires are okay. Use the same method with the battery with the wires from the back of your stereo. Make a small cut on the wire and attach the short wires you used earlier.
check your speaker wiring, make sure both terminals are connected properly. or could just be left speaker is disconnected. and is set in stereo mode which will only play left and right front and Sub, if you have one. try chaning the surround mode to play in multi channel speaker which will send sound to all speakers. i trust your using a Digital audio cable from your source ( cable box, DVD player) if your using analog audio cable you will only get stereo sound, and nothing will ever come out of the rear speaker unless you change the surround mode to multi- channel speaker. also in the setup menu you should be able to perform a speaker setup, make sure all your speakers are able to produce sound. follow speaker setup mode in menu, make sure you have checked the boxes or Yes to speaker you have in your system. then perform calibration and a test tone will come out of each speaker as you select them.
Check the connection on the back of the receiver. Check the balance setting, make sure that it's in the middle. Try another mode like stereo, you should hear left and right front only. Also, if your receiver has an on screen menu, check the dB levels for the front and rear left speakers. Good luck!
It may sound silly, but can you check all your speaker cables again and confirm whether they are connected to the right connections. please check all cables as also the severed one and please repair it also.
Now please go to the system-set-up and do an auto setup and set up your speakers. Listen to the test tones and confirm that they are coming out of the correct speaker.
Once these are set, then if still there is mismatch of sounds, then we could further trouble shoot.
1) just trace the wire of working channel and plug out that and connect to opposite side of that channel
for example: if front left is not working, remove pin of front right and plug it into front left
after that listen the sound if front left is working then no need to open amplifier just check the wires of satellite speaker which is not working
how to check broken wire:
1) just observe your speaker nearly if you found any screw holes open it, if u can not find any screw holes remove front net which is fitted by press lock or any stepped groove, you can remove that and if you are removing front net you have to open speaker from casing then after you can find speaker's wire shouldered or bolted to it just check wire and go on after that u'll be sure that weather your speaker is failed or wire!!!
With the radio on u will need to push audio button it will change to something different on the face push until speaker balance comes up & then push butons below it left or right to balance each side of speakers. For me it was the left speakers that i needed to balance good luck John
Hi, since the speakers themselves are ok, try checking the BABY PHONE PLUG that goes to the music/sound source. It is normally three (3) in 1 stud. The metal topmost would go to one channel, followed by a blak plastic ring then another metal band which goes to the other channel, followed by another black plastic ring and the final metal part which is the ground. With power on to the Z-5300, try touching the ends of the baby phone plug. Touching the top and 2nd metal part should produce a sound on either of the left or right. No sound (but spkrs good) it is possible that the left channel (front and rear) of the amplifier is dead. Hope this helps.Regrads.
So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck
