Hello there. So I recently acquired two G3 Molar macs from a friend. Both were stated as having screen issues. Neither of them work. One will give a mac bong and the other wont. Both will power on and display the green led and I can hear the fans spin up as well as the HDD's on both machines. I have tried the cuda reset on the mobo but am unable to zap the PR ram. Took out the memory sticks and tried one at a time still same effects on both machines. I even swapped out the personality cards to see. Both still work. Unsure what the issue is. Thinking the mobos might be bad. Also I tried hooking up external monitors to both machines and neither would display an image. Will the monitors not turn on if a certain test fails? Any ideas are appreciated. Thank you so much.
