Hello to all!

After spending some cleaning (score reels, player unit, etc.) the machine developed an odd behavior at start up:

I will turn on the machine and:

- "match" number is lit
- "Game over" is lit
- Plenty of credits on wheel

Pressing the start button at the door nothing will happen, -but- if I manually push the "S" relay the machine will reset all the score reels back to zero, drop targets will be reset, ball 1 will be lit but no credit will be taken from the credit wheel, nor flippers will work or scoring can be done, ball is also not ejected to the shooting lane.

Any ideas?

TIA!
