Ok my p/t job is pat testing, so we go around schools offices etc testing things that are pluged in, this includes projectors. Now we do an operations test which means powering up the projector for 5-10 seconds, now this isn't following the correct turn on off procedures for projectors, but does this procedure only apply when the lamps are hot so the fan stays on to cool them down? Or is this infact potentially damaging the projecter. There is a debate going on at work to change this 5-10 secs power on, but only if it is damaging. So OCUK can this damage the projector?
