I felt some of the soldered rams were warm . this machine had an a501 installed. What I tried was to disable all the VCC supply going to all rams asto check if I still got a green screen. I disabled voltage to rams and still green screen. So what could be the issue? . Is there any jumper I need to move to enable the external a501?
Green screen means there's a problem with the chip ram bus. Either there is a problem with the Agnus, there is a problem with the onboard memory, or there is a problem with the traces and components connecting them.

Disabling onboard chip ram will still give you a green screen as it will fail the poweron check.
