Projector blinking blue power light. non stop!

depends on how many times the orange light blinks also when you replaced the lamp did you do a timer reset? you can find alot of information on how to trouble shoot this www.infocus.com/support

To jmatthews

Both power light and status light a solid red with no response to any buttons indicates the bulb timer has expired. You need to reset the timer by pressing and holding the left arrow key, the right arrow key and the power button all at the same time for a few seconds.

If there are no problems, the projector will fire up, but you must replace the bulb as it will fail soon and perhaps explode when it does.

Take care

SOURCE: power light blinking red

if the lamp goes out after the red led goes on, there is a fan issue and the projector is overheating or the ballast/power supply can't hold the voltage.

SOURCE: Projector screen turns off after 10-20 seconds

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

SOURCE: the projector lamp does not turn on

I have done this on several of our PT-LB50U's with sucess every time.Remove lamp cover and lamp.Then remove top of case by removing 6 screws on bottom.Remove metal shroud that would cover lamp 2 screws and remove 2 screws that hold lamp plug and move it away.You will see a little blue lever for saftey switch move it back and forth from top and bottom put back together and should turn on.
