On my Flintstones, hitting the right flipper increases the score 800,000 points.
Unfortunately I can't just do a switch test to see what's being triggered because I can't activate the right flipper during a switch test.
Has anyone had a similar issue?
Your on the right track with vibrations causing a switch closure. I would put the game in switch test and knock on the playfield near the right flipper to see if you can find the switch closure.
Ok, wasn't from vibration but inconsistent 12v supply to the drop target opto board due to the jumper for the dino/building led mod. The "D" bedrock drop target was blinking when you hit the flipper.
The voltage drop? from setting off both right flippers simultaneously was messing with the opto board. Removing the jumper out of line for the dino mod corrected the problem.

Today I noticed the exact same problem with the right flipper that increases the score by 800,000 and the blinking "D" in bedrock.
It also suddenly starts the "go for the strike" mode without it being fired, I wonder what could have caused these problems.
Could you please explain me how did you fix your problem? I didn't quite understand
Thanks
The 800,000 opto problem is going to be on the opto bank for those drop targets. Try cleaning the optos.
As for the go for strike mode I’m not sure what switch triggers that. Pull the glass and test switches during gameplay to find out which switch triggers that mode. If the switch is an opto it may be dirty. If it’s a micro switch check the solder joints on it or the switch may be worn out.
To fix my D drop bank problem I had to replace the opto for the D target on the board.

Thanks for your answer!
It was this board:

It was the "O" of Rock that was causing the problem (not the D as I wrote before), by disconnecting the board the problems went away.
Do you know how the board is called so that I can buy a new one in case cleaning it wouldn't fix the problem?
Edit: maybe replacing the opto is enough
Edit2: fixed. cleaning everything with IPA, even ribbon connectors and pins, worked fine
