Quoted from CharlesZ:

Still waiting for C30 to come in the mail, so no update there.
I've posted a full 30 minute video showing the moment I hit the switch to when the game becomes fully powered up and ready to go with all displays, flippers, and controlled lamps working.

What would cause the power to be distributed like this when powered up?
The game boots into attract mode but is basically dead. SLOWLY power is distributed to the displays, the left playfield controlled lamps and backbox "millions" lamps, the right playfield controlled lamps, the backbox bonus ladder lamps, and finally the lower playfield controlled lamps. The CHEESE insert lamps are always the last to light. It always follows this exact methodology. It's as if the game is being powered up with a Variac and distributed as stated above.
About 1:00 minute in I start to go through the audit and adjust options to ensure the game is in attract mode since it's hard to tell. You can see the four digits changing and the five "bongs" indicating the cpu is running as I try to work through the menu screen basically in the blind. The four digits that do appear on the displays say "Free Play Press Start". I go through the tests a few times and little but the sounds work.
At about six minutes in I power cycle the game to ensure it's in attract mode.
It used to power up this way AND power down this way during game play or attract mode but replacing Q50 seems to have stopped the powering down aspect. I can leave the game on all day (12 hours or more) and it will be fine. Turn it off overnight and it has to "warm up".
I've had the game for 10 years and this only started to happen recently. It hadn't been played for about a year but remained in our living room unmoved.
