Diagnistcs LED #1 only blinking

Metin:

Recently my iMac stopped booting. The only audible cue is a very faint clicking when using the power button. Upon opening it appeared diagnostic LED#1 is constantly blinking when supplied with power. My first repair-attempt was replacing the PSU board. Unfortunately after replacing it the situation hasn't changed. Anyone have any clues what to look for?
