Optoma ep755 wont turn on just quietly clicks

So i was having the fan fail problem and i cleaned it out
and it worked fine then a few days later this happened.
you turn it on and now nothing happens except this quiet
clicking or turning sound then its off again.
now jsut to make sure does this sound like i just need to buy a new fanĀ 
for this machine. cause the light isnt turning on either...any thoughts

    I turn on the projector and can hear a slight clicking sound, after a minute or so the red lamp light goes on. A minute or so after the projector returns to its stand-by mode.



    I heard replacing the ballast will fix my problem, does anyone know where I can purchase one and a how to replace the ballast.



    The lamp was replaced so I know its not related to a lamp failure.

    i have 2 of these ep 739 and after being in a club which was filled with smoke machine smoke, both units started over heating and turning off. an overheating message is displayed and they go into stand by mode.i checked the fans and they still seem to run fine, i was thinking that they may be running slow due to a build up of gunk in the fan motors? it seems some bhow logical if i place a large fan on the outside of the projector this doesnt happen.
    clarity on this isssue would be great
    thanks

Optoma HD 70 turns on with lamp and temo soiled lights


Asher fadida and alll,

The issue:
solid red error light?
HD70 "die's" after few min with strage noise?
flickers different colors before complete self shutdown?

well try this....

Before replacing your bulb, fan or any other component try first cleaning your optoma realy good!! HD70 doesnt comes with any kind of filter so you can imagine the amound of dust can be.
The most importent thing is to blow away any dust from your color wheel + the sensor attached to it .

for farther troubleshoting clean your fan's.
there are 2 fan's insinde the HD70.

probably the most problems will be solved by cleening the color wheel!!
if the problem is not solved ,chack the lemp and the fans if they work properlly.

For fan replacing:
Fan Part number: GM1207PKVX-A

Optoma hd65 projector new bulb wont turn on...cant reset timer!


I think it's a lamp driver issue from what I've seen others have gone through. I also read that if you go through the sequence of unplugging, plug back in, wait 20 seconds and try to turn on, multiple times, it will finally kick on and work. I just got mine to turn back on by doing this and waiting through the fan cycling without the light turning on. After the 4th sequence the light flickered. After the 7th sequence it finally turned on and is working. Now I can watch the Super Bowl and will look into replacing soon.

Lamp has stopped working.


Hi there,

thank you for using FixYa.

How many hours has the lamp done?

They are generally only good for 2000 hours, when hot do not touch, move the unit ect as this can damage the lamp. Never touch the glass part of the lamp (it is not like a light bulb).

Regards

Only power light will power on for few seconds then flashes.


Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.

I have the same issue, I have figured out its a fan issue, my fan must have went out. After about ten minutes the bulb will get too hot and the picture will start to turn a way off tint color. I put a fan on my projector and after about 40 min. the picture returned to the appropriate color. I am still investigation on how to get and replace the fan.

Optoma H56 - turns off just after start up.


It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.
