Hey guys. New to the hobby, but have been subbed here forever.

I picked up my 1st game. A Robotron that's been put into a moon patrol cabinet. It was not working initially.
So far I've replaced the power supply (it was converted to switching)
It had a bad ram chip, so I had to replace one of the 4116's and now its booting without error, and I can hear the initial startup sound.

My issue is that I have nothing on the screen. Well I have something its a lightblue'ish screen with some diagonal lines (pics attached)

I do have a cap kit on the way, but I'm just wondering if that's going to even help with this specific issue.

I'm hoping someone here recognizes this specific screen.

I do have a thread on KLOV going as well, but I thought I would post here as well since you're all bro's lol
thanks
