iMac G5 (iSight) do not start up (A1145)
The computer (iMac G5 20") was working perfectly for the last 8 years.
I shut it down on Friday and on Monday could not started up. Dead!!!
I open it and changed the PRAM battery, just in case, but the problem still persist.

Now, I have notice that the power supply was making a noise (tik-tak-tik-tak, tic-tak...) but after I did try many many many resets to the SMU (http://support.apple.com/kb/HT1767) since then is just making a very very low continues noice.
After doing some research I found out that there are 4 diagnostic LEDs on the logic board under the right speaker.

In my case LED No1 is ON while the computer is OFF.
After the reset LED No2 flashed for half a second, the fans were just moved for half a second but still the computer can not be started.
Any idea what would be the problem?
I guess the problem is the power supply, but before I go out there and buy a replacement, I would appreciate any help from anyone who either experience the same problem, or knows anything about it.
Thank you in advance.
