Cannot connect to PSN on OFW help?

[dekaspace]

Ok my console was working till I took it apart to look at blu ray drive, I gave the unit a clean and replaced paste as per my other thread, it picks up the signal fine, 85% in living room and 100% in bedroom, gets ip address ok, internet connection is ok but fails at PSN.

Any ideas?

What error is it displaying, check it down the screen & tell me.
