Why would my projector refuse to start with a seemingly intact light bulb?


If you only have 300 hours on it it should still be under warranty. Before doing something to void that I would check with Optoma techs.

Power indicator /red/ and warning led/red/ are lighting after ea 15 sec. a lamp never start and fans goes in OFF mode. I checked power supply lines S5V,S-5V,S16V on the Main Board . I checked unit lamp...


If power indicator light red and warning indicator red flashing than according to user manual :-
The projector has been cooled down enough and the temperature returns to normal. When turning ON the projector the WARNING indicator stops flashing. CHECK AND CLEAN THE AIR FILTER.
Experience:- 1. if the temperature is very low than temperature sensor maybe misbehave.
2. If anyone fan not working
so please you check fans.
(If lamp or lamp ballast unit faulty than after a time period the lamp indicator light ON not a warning indicator. I experience many times if any fan in projector are broken or jamed the temperature light if present otherwise warning light ON or flashing)

is it fast clicking like something hitting the fan blades, or a slow almost popping noise while the lamp is lighting? if fast, check for fan blade obstructions. if slow, you have a ballast that is trying hard to strike the lamp. if the projector is past warranty, you might want to get a new power supply from an infocus service center and replace it. try av solutions in ny. they re really good. www.avsolutionsny.com

PT-AE700E projector appears to have gone kaput - not lighting up.


Because of high voltages and heat, there are many safety circuits inside these units. If you have a spare lamp, try replacing the lamp. Initial checks are made before the lamp is fired and sometimes a defective lamp can cause this. Also, can you descruibe what you mean by "noisier than usual"? Is the fan making more noise? Something elase making a noise?

Thanks,
Dan

InFocus LP725 light goes out after 10 minutes


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help

Sony VPL-CX4 projector locked up


keypad buttons probably need a good service.
you say you pushed power key twice
did you leave a small pause between each push
get a tech to checkout underneath keypad buttons to make sure that the contacts are clean.
