I have been using the above projector for about five years without problem. The other day I turned it on nothing happened. No led, display, fans, and no noise. dead as a dodo.. Having read a lot about the psu problems I obtained a replacement psu board from another LP600 and fitted it today. I now get led, display and fans working but the lamp does not work. If the lamp has gone would I get any symptoms apart from the lamp not working. Am I safe to assume it is the lamp and order another one? Any suggestions appreciated..
