Mac won't boot / Only 1diagnostic LED

crwdns2934249:0crwdne2934249:0:

Well, another case of boot failure with only the first LED (501) lit.[br]

Actually, I’ve already tried everything that’s been recommended here.[br]

On pin 4, 11 and 12 I measure 11,93 / 11,94 V. [br]

Could this slightly lower voltage be the reason for the Mac failing to boot?
