OK, back on this!

I got that game as 'not working'! It's time to plug in and see what happens  Roll Eyes

...as expected, nothing! No monitor activity, no marquee light, no sound... nothing!

I love these symptoms... it could be a simple power supply problem, fuse or even a simple security switch disconnected... Let's open the cabinet  arrow



This cabinets looks very clean at first sight... now let's see what behind the curtain piece of cardboard ...



...the boards look not bad...



Damn! It looks like a pinball here  shock  arrow



I can see the incoming 220V, but still no output behind power brick... what the hell?

Christ! There's is also a security switch inside the coin door, and of course because the the coins mechs are missing ... no contact so no voltage!



It's the first time I see a security switch at this level?!

Ok, after 'by-passing it' for my test, I can see 'activity' on boards, here  arrow



Got now the marquee on, a 'now powered' monitor displaying a black screen. No sound, no credit sound, no game test mode... nothing!

Let's look closer here... a led supposed to indicated the presence of 12V here  arrow



Looks good, and here... I'm supposed to have 5V  arrow



Not good! what could be wrong? Let's check the fuses everywhere. They are all fine, but see this support  confused  arrow



... and the modifications here?  Roll Eyes  arrow



Well, the problem was the fuse support. 'temporary' fixed for this test...



...and got all the led on! Now I have something 'static' on the screen  Cool  arrow



...but still no sound, no on screen activity (still the same static picture), test mode without any effect...

So I've checked the voltage incoming directly into the game board, and the values measured are too low / not correct. Looks like a voltage problem at this level.
In addition I'll have to check the harness and understand what was the purpose of the hacked/cut wires...

Funny to see how the boards all most look the same...:

Krull:


Q*bertīs Qubes:


-EDIT-
On a second glance, they are all most identical, only difference is the daughter board on the QQ and the small PCB on the Krull (left of it)

Maybe a stupid suggestion, but did you flip this switch ?

Looks like it is set to test mode  Roll Eyes

I'll have to fix some voltage problems first, and understand why some wires are cut /hacked  Undecided

I didn't check too closely any Krull arcade videos game play so far (I prefer to discover it when the game will be repair), but I had to check your video link  Wink
Cool, now I really want to go forward on that restoration to play these 'scenes'  Smiley
(because no progress so far on this one  oppps)
Thx for the link Smiley
