This is my very first table and it was working great for the first week but all of a sudden the game stopped working.
I notice on the MPU the green LED flashes Once and then stops and all the lights come on but the game wont complete its boot up sequence.
I have ordered new fuses to swap those out to see if that helps.

Any one out there have any advice?

Thank you in advance

It does not have the original battery
The person I bought it from installed a vRam chip I believe is what he called it

I did carefully do that with all the connectors and still no luck

I also looked under the play field to see if anything was burnt out. I do not see any burn outs on any boards or any solenoids underneath

Power it up while J1 is disconnected?

I read that about the U7 somewhere else
Is it easy to take that Ram off of U7?

I have never done this before?

Ok I will try that as well

Forgot to mention that when it happened exactly

It happened like this

Turned on the machine, it booted up properly
Was able to put in 3players to play the game
I started to explain the games rules to my friends when I was done is when it died out on me. With the scores blank and then I tried turning off and on and it turned on but only had the 1 blink on the green led from this point on

Idk if this info will help anyone pinpoint things easier

Thank you all so much for your advice
