Dramatic increase in fan noise

I have had the H56 projector for around a year... I have not had any problems with the fan noise until recently... It seems to have gotten 5 times louder... I'm not sure if it is the fan making this noise... when i first turn it on, it seems to make the noise even before the fans start. Anyone know what this might be? Thanks

Re: dramatic increase in fan noise

Hi there

If you place your hand on the machine and you can actually feel the vibration , you might be looking at a faulty Colourwheel.

If not , try cleaning the fans by blowing it out. If the problem still occurs you might have to replace the fans.

What is the purpose of the coolong pump? What sort malfunction could occur due to that?

This system uses a cooling pump, to pump high pressure / high velocity air around the lamp dramatically improving cooling efficiency.
With this new cooling system, the body can be further reduced in size compared with ordinary projectors that use a single cooling fan.

If the cooling pump fails then the lamp will overheat and shut down

I have a one year old epson ex51 and was working great until last night. Since last night the fan noise has increased significantly. Does anyone know how to fix the fan noise?

Mine just started doing that too. I'm pretty sure the fan blades are rubbing against the casing. If you have had it for under a year, call and get it fixed, but if its over a year you're on your own. I nudged the fan with a metal hanger, and it has stopped making noise. I think eventually I'll need to take it apart and get a new fan for it that has better bearings.

I have an optima h56 and when I turn on the power it acts as though it is trying to come on and then shuts down, and I do not see the light coming on from the bulb.

it's either the colorwheel, or the ballast. do you hear a high-pitched whir? if yes, the problem is the ballast. if no, the colorwheel.

I have a Hitachi PJTX100.....been using it for a year and a half and it has been flawless.....until recently....After about 30 minutes of use it shuts off....meaning the screen goes black and the actual...

i believe your problem is heat the bulb is getting hot and the air or fan is not working properly so when it hits temp it automatically shuts off check your fan air flow filters etc

Cooling fan problem projector

I have a similar issue though mine isn't quite as extreme as yours. Got a couple things you can do.

1. clean out the projector with compressed air. You might have dust building up on components that is trapping heat.

2. Your fan might be burning out. Needs to be replaced. I'm still working on trying to figure out what tipe of fan it needs.

3. The temperature sensor might be going bad. This one is less likely and most complex to solve as it depends on how the system measures the temp. I haven't checked in detail yet.

4. Replace the whole unit or send it in for repair. Both options will be costly...

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.
