Hello, recently a school gave me an imac g4 that was used for educational purpose and the school said that the mac was dead. So i first pluuged the power outlet and it booted but with a weird screen changing to completely white. A few weeks ago and yesterday, i just replugged it to test the mac but now, the mac won’t boot up, no fan nothing. Only a fast clicking sound coming from the power supply that stops sometimes after a few seconds. I dissasembled all the imac and look for any damage on the mac. With a multimeter i checked the voltage coming from the first power supply board and i got 400 v continue but on the second board, i have no voltage. Have you got any tips to look for maybe shorted parts or capacitors that usually break up in these machines ? Thanks for help
