Ok, this is going to be the first video in a series of Repair Videos for a Playstation 3. As a side note, i am hugely disappointed with the lack of information out there on repairing the PS3, its basically, replace the part with a used one off ebay, which is BS for how popular the thing is.
But anyways...I buy broken PS3's from ebay to repair and sell, usually they are pretty basic cooling problem i try to shoot for. But this one, seemed like a good investment, everything boots up, but occasionally it will boot and do this "Green Snow" effect. If i can get it too boot and be problem free for a few minutes, it will run totally fine until the next reboot.
So i've removed the Blue Ray drive, and the front Media Card Reader to get it as barebones as possible to diagnose the problem.
After doing some voltage readings, i noticed the 12v, 2 x 5x, and the 3.3v were all a bit lower than spec...which is usally ok, but maybe its a prelude to a powersupply problem, or possible the board for the 60gb model just wont tolerate that variance to due a previous overheat or something.
So i set out to hookup a high quality CoolerMaster 550w power supply i use for testing computer motherboards.
Basically the only thing proprietary about the PS3 power supply module is the way in which its powered on, it seems to always be on in some sort of standby state of which the motherboard can wake it up.
But non the less, this is just a energy star kind of feature, the PS3 could care less if the power supply goes to standby when the board is power off....and so could i when it comes to testing.
So i just bridged the Power On connector of my ATX PSU, wired up the appropriate voltages, and turned on the power strip. Board standby light powers up, power button works, and it boots no problem.
The video shows that im still getting the green snow effect, however, it seems to happen only half as much as it does, when the sony psu is placed on the system. I am starting to attribute this to a possible fuse or resistor bad, or going bad and the more accurate voltage coming from my ATX PSU is able to reduce the effect and get the system to a working state
BTW - This is a 60gb model PS3, so its also running the ps2 engine....this model is known to be problem matic.
For the love of god, Im not looking for a bunch of you to post about how i should send it to sony and pay the $150 for repair, I bought it out of warranty and the previous owner already opened it before i did, so its not an option. I'm taking the time to post this so other people looking to repair a ps3 for low cost can learn from, not to get your 2 cents about the warranty.
