Data east JP gi string out.

[David_Vi]

Just got JP back and noticed half the backbox lights and the topper lights aren't working.

They're the same string, white/green and green.

All fuses test ok.
Took a quick look with @Spandangler and noticed F7 0.5amp is blown and blows straight away when replaced. I wonder if this is a red herring as it doesn't appear to have anything to do with GI? Can anyone confirm?

What does F7 power? The game is working fine other than the GI.

What do the connections on the power board look like, hopefully none looking toasty?

The board ones are ok, one of the z connectors the backbox gi is really toasty on two pins but not the dead ones.
I'm trying to find a connector with 6pins to redo it without the Z connector but struggling to find any.

fuse. connectors. ?

fuse. connectors. ?

Fuses are ok except F7 which doesn't seem tied to GI, but Id like to be proven wrong as the schematics are proving hard to read.
I think f7 is for the dmd but we're using a pin2dmd which doesn't use that power line, for all I know it was blown all this time and a red herring.

f2 ok? for sure?

 

[AlanJ]

otherwise it’s a broken wire / dodgy connector.

We fixed it. Was way more complicated than a fuse. We had to have oscilloscopes out and everything. Welder. Angle grinder. Sorted in the end.

Why'd you do this, we look like a right Mickey mouse operation now


It was a fuse but on a different board hidden behind a wire harness

Oh the old “hidden fuse” excuse
