Sega Saturn White freeze on bios screen!

I have an white Japanese Saturn. There's no start animation with bootup sound, it just shows the Saturn logo (as if I had pressed Start to skip the animation) and then freeze. I can reach the time and date if i take out the battery.


I really have no clue what could be wrong?

 

Have you tried a different controller or even disconnect the controller to see if that changes anything?

 

Dirt on the motherboard, it's a weird issue but that's what happened with my Model 2. Druid can confirm this too, he knows heaps on the Saturn.

 

same problem without the controller inserted.
I already cleaned the motherboard with tops and alcohol. Maybe i shall try to clean it with water and soap and let it dry for some days?

 

Water is really bad for capacitors.

Maybe the board has a broken trace somewhere?

 

Any suggestion what i shall do? buy a new motherboard?

 

i have the motherboard with an separate board for the controller ports. If it was working shall it boot with the controllerboard disconnected?

i have been cleaning everything a second time with air and alcohol but i get the same freeze every time? strange, cant find any broken traces or broken capacitors
