I have a CECHC03 PS3 (fat) (PAL model), with a fan problem, and also a video problem (weird colors are shown, you can see it in the video link below). Shortly after booting the ps3, the fan speed increases and keeps increasing until its at its max. The screen also glitches with weird colors (video out is on component) and freezes when the weird colors are shown. I have opened it up and tried turning the unit on to see if it was a ventilation problem but it gave the same results. The (internal) Power Supply for it is an aps 227.
Here is a Video of my ps3 and what happens when it is powered on:
If you skip the video to around 1:00, you will hear the fan getting louder.. and louder. Someone gave me this ps3 for free because they were going to throw it away. Any help/suggestions for fixing this would be appreciated.
