128 High end Pioneer Elite SC 09 TX receiver repair

This hiend beast stopped turning on. It is very complex and weighs a ton. It was quite tricky to investigate the fault. Even a DSLogic USB logic analyzer by DreamSourceLab was used (perhaps was not necessary, but was fun anyway). It was found that the clock generator of the main MCU was not running. Also a reset was needed, which takes a secret combination of buttons on the front panel.
