JV-880 Audio Troubleshoot & Repair
 
Hello,
Since starting this thread: Roland JV-880 No Audio
I have aquired a nice soldering station and have been repairing and upgrading various gears.

This Roland still has same issue, lightly tapping on PSU board audio cuts in and out.

Think it is time for me to learn all about diodes. If that is a diode in the image I am pointing at, ** yes, based on the symbol, it is a diode*

it is very sensitive to the issue. Everything else around it is secure.

If you have a great resource or preferred educational outlet, site, book hit me up.

Any thoughts what so ever, please.
Even BS statements are cool, I find pretty much everything funny, except waves over bloated discount city affect for long term use and ik Multimedia's download and archive the internet to use two plugins.
