Just a little point in the right direction please.

On occasions my flippers don't work when I start a game. Sometimes they do, sometimes they don't.

I've tested them in switch tests and they activate and beep as they should. I also gave the optos a really good clean with some IPA not that long ago which removed a lot of dust and dirt.

What else should I be looking for? A mate has suggested replacing the U20 chip I think he said???

Thanks.

U20 on the CPU has nothing to do with flipper which run through the fliptronics board.

I'd reseat ribbon cable between CPU and driver board for a start.

Thanks LTG. Will have a look over the weekend.

This may also be as simple as making sure the coin door interlock switch is fully closing enabling the high power.
IF the ball is always kicking out of the trough though you can skip that suggestion because the coils are working and just not the flippers so a look deeper is needed but it is worth a glance if not. The bracket that closes the interlock switch can easily bend back a bit and not engage it well.

Thank you for the tip! The balls have been kicking out perfectly but will triple check this as well.

Why is it with this machine one issue opens a Pandora's box!!

Re-seated ribbon cables and now I have the VUK constantly firing when the game turns on?! Originally it was one of the Juggler holes, now this?!?

Thoughts please.

We have a CV in our club and it has been a PITA sometimes by locking multiple coils on at start and other random stuff going on. Eventually we reseated the ASIC (large square IC on the CPU-board) and it has been working ever since. Also, some ribbon cables might need to be replaced, reseating them doesn't always help. The sockets in the header has lost its contact pressure and/or its plating.

My first test would be to change the ribbon cables with another game or new cables.

with the VUK firing it sounds to me like you might have an opto board issue. That game has a 7 switch opto board under the play field. I would start by reseating all the plugs (game off) on the opto board. If that doesn't help, try swapping the board from another game that uses that 7 switch opto board if you have one. TOM, TAF, TZ, ect...
