I’m trying to fix a nec np-m300x projector for our youth that is out of warranty. It won’t power up and the code it gives is that the lamp door needs to be shut even though it is properly shut. Upon tear down, it appears the switch (I assume a rotary switch) that the lamp door makes contact with on the circuit board is physically damaged. In speaking with a repair shop an hour away, I was advised to jump/bypass this switch as it is merely a fail safe to keep people from operating the projector with the lamp door open. How do I go about doing this?
Kevin, see if this looks somewhat familiar. It is from an MP-300 and should be similar to what you have. If so you can definitely bypass the switch…
