Yes, I have reaseated the interconnectors but still dead.
I will reaseat the game epromes and se if eneything changes.

Pinpall...

In all honesty, you are stabbing in the dark right now. Check the voltages from the power supply. If all are good then start looking at the CPU and check the test points there. You really need to eliminate the basics first.
I know it worked fine until now but all machines do until they don't.. that's what makes them not work anymore.
Im assuming you've tried staring at it for prolonged periods of time to see if it will fix itself??
