The Infocus LP240 will not power up. WE had a power surge and that may have killed something. I have two of them with the same condition. In desparation, I switched lamps on each other and tried to power up without success. Can someone please help with a diagnostics guide and possible repair manual to figure oiut which component has blown and how to change it? Much regards, Lalit.

power supply is bad and needs to be replaced. unfortunately, there are no parts for this model. infocus no longer sells them, and they were made by another company that no longer makes power supplies. therefore, no schematics either. sorry.
replace the power supply. the caps go bad on it after a while. you could get the part from and infocus service center and do it yourself or send it in to them and let them repair it. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
there is a fuse on the power supply next to the plug (on the inside), but this model of projector has power supply issues. the biggest being that infocus no longer has parts, schematics, or component cross references for the lp240. the circuit boards were made by another company that made had their own components and now no longer makes circuit boards (they make fans and bearings), and they have no schematics either. so, i'm sorry to say that the machine is doa. there are no replacement parts available and almost no way to fix the old ones.
it's just a line level signal with a 1/8" stereo phono jack. there is an amp and speakers in the projector, but they're meant for presentations, so there's not much to them. but there is no audio out coming from the projector, so you'd need a separate amp and speakers coming from the ps2.
