Hi all Just received a old PowerPC G5 2.0GHz Dual Processor. When i tried to power it on, the Power LED came on as usual and the G5 chimes, but it didnt display any video on the screen. None of the diagnostic lights display red, heres what i've done - Reseated all the RAMs - Pressed the PMU button - Tried CMD+Option+P+R but didn't hear a second chime - Swapped a good working graphics card - Swapped a good working display with good DVI-D cable - Tried CMD+Option+O+F my LCD idle light flashes from amber to green but after 2 sec back to amber (idle) - Tried holding down power button for 5 sec and heard a tone sound + LED light flashes - When i took the plastic cover off 1 Diagnostic LED turns red and the fan starts to run at full speed (which is normal) - The fan runs at normal speed if the plastic cover is in place. - HDD is detached but same issue when the HDD is in place. Not sure if the internal CMOS battery is still good, but i don't think it will cause such issue right?
