iMac 21.5” does not power up, no chime is heard. I know that LED codes are: LED 1 on= trickle voltage from power supply is detected by logicboard. LED2 on= logic board has detected proper power from the power supply when the computer is turned on.
The problem is BOTH LEDs 1 and 2 are BLINKING (not ON continuously) when I connect the AC power cable to the mains wall socket. What problem does this point to?
