Let me start with just a few basics.
Try powering off the machine, then pull out and push back in (firmly) the MPU board and power back on.
Also, inspect just to make sure all the connectors are seated and that nothing was pulled when you removed the MPU.
Hey man,
Thanks for the tip,
i already replugged everything thinking it maybe was a loose connector.
When checking, behind the screen there is some old contact( i think they are contact) and maybe the problem is there?
But its a hassle to get the screen of because its an old crt, and i think the cable of the tv inside is a bit short to get it removed.
i wil try again for sure to check if everything is connect rightly.
thanks in advance for the answere.
Do you happen to know anyone with the same machine i would like to buy the manuals of this machine.
great day.
