Malungu, where does the self test stop. You should see a row of five bars. Whatever number of bars is showing is significant. There should also be an error code on the bottom left of the screen.
All the best, Ron.

Malungu, If you send me your email I will send you a sheet that shows the startup sequence. Have you checked the power supplies for voltage and ripple/hi freq noise? If you don't have a service manual there is one available for free on the GE site.
Ron.
