Default PS3 Mobo red light

Ok guys. I recently got a free PS3 Broken. no warrenty or anything. and i thought i could fix it.

So, after i cracked her open, i saw liquid on the MoBo... that's always a bad sign. so, 3 hours after scrubbing it down, I tried it. but... no go. so maybe the PSU? nope. wired it up to a ATX and still same problem. Oh and if you are wondering what its exactly doing. It turns green 1 sec yellow then 3 beeps and blinking red light. So i decided to be meticulous and i have my volt metere out and now i want to test all the contacts to see where I may be having problems... but I do not know how much voltage is suppost to go where. And.. I'm no electrician of any sort.

So my question is. does anyone know how to test a board properly, and does any one know where a MoBo schematic could be found. thanks.

They don't exist to end users.

The issue your encountering is a YLOD. Yellow Light of Death. It is caused by the BGA solder joints under the CPU/GPU disconnecting from the motherboard because of heat.

Only way to fix this is to reflow the BGA for the CPU and GPU. Lookup PS3 YLOD Fix.

Try baking the motherboard, like some managed to bring GPUs back from the dead after a 200F (is it?) run in the oven...

I know nothing of the PS3, but best of luck with the repair. Let us know how things go!

Have you tried taking out the HDD and reconnecting it?

Seen a couple posts around google now about the red light meaning a hard drive failure.
