HD67 Black Spots?

Hi - Got a 2nd hand Optoma HD67 on Ebay last week for £300. Was very pleased as it only had 12 hrs on the bulb and seemed almost brand new (as described in the ad).

Got it mounted on the ceiling, new hdmi cable & everything was cool until this evening, when I noticed lines of black dots across the screen. Thought it might be my cable, or settings but it's the same with no cable attached and a blank background.

Googled this and it seems like some kind of stuck pixel / chip problem, but all the problems I saw were referring to white dots or white & black dots - mine are only black/dark.

How could this just happen overnight? Any ideas what is wrong? I left the projector on for a while and some of them seem to be correcting themselves / disappearing???

Thanks
