    Check basic requirement of KBC first and post the measurements here.

          @techtiger,PSL Logic is most likely working as he has 3/5V standby.

                Look at page 97 of schematic, there is a 'power up sequence diagram'. Start with step -7, -6, -5, etc..

                    Don't blindly replace parts, it can cause more harm than good.

                    Start with finding out why RTC voltage is missing. Do you have a power supply? It'll be helpful to know what the current draw is.
