Please help guys. I been having this problem for 1 week and haven't figured out the answer yet. Hope someone came across this problem and got it solved. Left left is fine. Right one is very low.

Thanks in advance.

I have had this problem for years, and the only solution I found is every 3 or 4 months (when it happens) I open up the case and press down the plug on the CN2 connector on the output board. This seems to return the right volume to normal until it happens again. I have been trying to get a replacement cable for ages without any luck, so I just keep using this remedy.

Hello Tassy, thanks for the response, Please tell me where is the CN2 located, which part of keyboard. If I open it the keyboard I will be very confused cuz I have never opened it before. Thanks .

I do this correction every half of year.
For others, CN2 is located in the middle of output board. 2 black cables from master volume place

Is it hard to open the top case from the korg. Do I have to unscrew everything? Thanks Gino and Tassy.

I have a sketch of which screws to remove, but I don't know how to insert it here. It's a MS Word file.

I converted the file to a jpeg and uploaded it here, I don't know if it works.[/img]

Heyy again. I finally opened the case, and tried everything, pushing the cables and other things in, I followed the cable from right speaker and also pushsed that, but nothing seemed to help Sad

Then I'm very sorry to say you have much bigger problems than me.
Probably your best bet is to take it to a service centre. Although I took mine to a service centre 3 times and they couldn't find the problem.
I only found it because I opened the case when the problem was present and checked each lead one at the time.
BTW. I have heard of someone found the problem was from the volume slider.

PA80 is simply a stupid keyboard to work with. I have it for the past 12 years and have driven me crazy. So many problems. But need to have it because our styles have been made for it. And I keep hearing it from every body. All of them have speaker problems.
