I have a MCS Series 3236. I hear sound from the right channel only. The watt meter for the speakers, only indicates signal from the right side.
I was using MCS speakers and I have changed those out with other known to be good speakers ( tested on my friends JVC stereo system) Still no sound from the left side. Out of curiosity, I plugged my stereo head phones into the head phone jack of the 3236, and the head phones mimic the speaker problem.
Out of curiosity, I attached a stereo cassette tape deck to the MCS receiver. and Surprisingly, the recording meters indicate sound levels on both left and right channels.! Also the tape deck records sound from both channels! I recorded stereo music onto a cassette from the FM receiver of the MCS 3236 !??

Can you tell me what is causing the problem and where I will find that problem inside? Or give me tips/ suggestions/ direction to direct me to the problem?
I checked both fuses to be good, and they are good.
while I wait for your reply, I am going to look at the solder joints on the underside of the board, maybe I will find cold or cracked joints.
Do you think the problem could be with open coupling capacitors? but where exactly would they be located in my MCS? and where would i buy replacements? and is it truly worth the money to buy high end caps?
or will OEM caps be just fine?
would I really notice a significant difference in sound with high end coupling caps?

I thank you in advance.
