have you got slim or fat ps3?

i think its connect hdmi to other devises or something like this
i dont remember exactly.i put that on reset and it works.
yes it is a slim. But how did you fix it?
I had this problem cause of a faulty and low quality hdmi cable, and had it again with a cheap hdmi input selector. Try using a different hdmi cable. If that doesn't work as well as all the other suggestions you've received then I'd say your mobo is bad and your only chance of a fix is an out of warranty exchange or possibly a board re-flow.
