Sigma-aka "mikohn" yathzee bonus error

[PWRSTROKE]

This is some info for the yahtzee sg-300 upright which very little tech. data is out there for the bonus section.  I had two of these and still have one-My mother in law has the other so you might as well say I maintain them both.  Problems occur with these mostly with the bonus section.  Most common is a "bonus error".  Numerous things can cause this,  Most common thing is the pwr supply in the top box left side.  The fan gives out and cap.(s) blow.  When this happens you will have bounus sys error and be pulling your hair out!  .  The other symptom will be upon pwr up the top dice Will not spin.  Have not isolated which cap(s) blew but just the root cause as I replaced the whole pwr supply and kept old.  Just wanted to share as this game is tricky and mis-leading to work on but a lot of fun to play!.  -Barry
