To get specials lit up you have to knock the 4 white targets down first then the red target last it cant be the red one first.
Well it was working in that order but now if only one target goes down special lights up even if you hit the red one first. Specials light should not come on unless the 4 white targets are down.

Diagnostics test done normal.
Yes it lights up if any of the five targets drop.

In diagnostics it reports the numbers between 30-34 for targets.

I dont know too much about system 1 machines i mainly work on em machines.
So i am trying to undetstand whats going on here. So in diagnostics mode all switches are closed and the game rom i will check in the morning and report back. What ic chips on the
Driver board control the targets. And if you could please post some pictures of under the playfield.
Raff

Thanks for the pics. The rom is E thats the right rom. Could the edge connectors cause this problem. IMG20200205204516 (resized).jpgIMG20200205204406 (resized).jpg
You can see the white targets still up and the
Specials on.
Raff

Yes

Is there any connectors on this
Game that could cause a fault with the targets and special.
Raff

When the game is first powered on there is no fault with the targets it always starts around 5 mints into play.
When the fault kicks in, the target with the blue arrow

Highlighted suddenly the sound goes dead only in that target but still gives the bonus and score. Sorry maybe i should have said this from the start. The diodes check out good power all going one way. I don't have any other board to put in i had a dragon machine but was sold.
And when this fault kicks in when the ball goes through the top right gate

It gives three bonus and then it straight away subtracts the bonus.
Raff

Yes.
I think the problem is the rom chip E would that chip cause this problem.
Raff

I say it is the rom chip one of the legs was broken before and resolder back and two other legs on it looked like they are going to fall off.
Raff

If i turn the game off give it a 10 mint break turn the game back on the fault is gone and that rom chip is burning hot to touch.
Raff

Sounds good so super glue the heatsink to the top of the rom chip.
Raff.

Thanks lynnin will do I was thinking that when the glue heats up it wouldnt stick i might be wrong but anyway a heatsink will be going on tomorrow.
Raff

Bought the hinksink it was for a Raspberry Pi,

Put it on the chip left the machine on for a couple of hours played around 10 games no fault so far so good.
Raff

Thanks to all that helped out.
