Doesnt turn on

open the bulb assembly and check if the bulb has fused / broken into pieces.if not then the ballast unit that powers the bulb is at fault and needs replacement
if the bulb has fused/broken , then probably the bulb that u had replaced 3 months back wasnt genuine!

I am going with cheap lamp if you can go oem.

Possible that the quality of the bulb is questionable. So please make sure that you buy one from the authorized dealer or one which is given a warranty for working hours /time.

I just fixed one Optoma DV10 that was dead, cold joints in power supply; resoldered and work fine now.

The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work
get a small fan and place it near the projector to provide
extra cooling. The projector is running border line on
high temperature and just needs a little extra cooling.

it seems that the powersupply is failed

Have a nice day!

Hi there

Take out the lamp and check for any marks on the inside ( shaft ) of the lamp. If there is marks or discolouration on it then you can be 100% sure it is the lamp.

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

I have a HP VP6111 projector that works fine on a table top but overheats ( overheating ) when turned upside down and hung from my ceiling. My solution...I went to Circuit City and bought two 80mm computer fans. I also purchased a 12V power supply from Radio Shack. I put one fan on front of my projector and the other on the back of the projector and wired them into the 12V power supply. I mounted both fans with velcro. The front fan pushes air and the rear fan pulls air. The projector now runs fine without shutting off. The fans are 12V and push 34 cubic feet per minute of air. I am very happy with this solution.
