Hey man, any progress? I have pma-770 myself and it is starting to get anoying. I keep loosing left speaker after this video i understood why display sometimes gets back on. Spraying switches with cleaning fluid and mushing buttons helps, but not for long so I am very interested in solving this for good, and your solution looks promising.
