It can be CPU, Agnus, Denise, a CIA chip, Gary, KS ROM, reset circuit etc etc, basically anything. Best way to start diagnosing a black screen is to find another working A500 and start testing the ICs one at a time.
Can you tell whether you get a black scren (with sync) or no video output at all? |
