Diagnosed off your site ; bought new power supply from you , ( US to Australia in 6 days ) ; swapped it in ; pushed the ram in really hard ; booted up and awaaaay we go . Thank you very much . Even us older folks can follow your excellent guides . Your help was invaluable and I hope to spend lots more time on my trusty old Mac .

The diagnostic LEDs are located to in a column next to the memory slot. Please see the image below.

LED 1 : Trickle power from the power supply to main logic board.

LED 2: Main logic board has detected trickle power from the power supply when the unit is powered on.

LED 3: Computer and video card are communicating with each other.

LED 4: Computer and LCD panel are communicating with each other.
