Optoma EP745 Will not turn on

We replaced the lamp, and when we went to switch it back on the projector did not respond.  The manuals simply tells us to call support, who cannot help us.Have an Optoma EP 745. The color wheel shattered. Am looking for a replacement color wheel, but when I first checked my lamp and placed it back in (it was OK) I had the same power off problem. Will not turn on. Am guessing that if I get the color wheel repaired, I will have the same problem. Don't want to chase goo money after a bad projector.

If one the main parts like the color wheel or the lamp are not in working order the projector will not power up.
Click here and try the phone number from the last post and see if you can buy the color wheel.
At this point is up to you if you want to spend more money to fix the projector.

You are correct, there gets to be the point of no return with this kind of problem, even if you get it working, something else will blow, and now you find that you spent all this money and it went to waste. It sounds like this is the situation with this problem, so instead of sending you to all of the websites to fix the problem, "maybe", I agree with what you said perhaps a new one is the way to go. I just hd the Tv in my bedroom go, and will not even bother with fixing a ten yr old tv, Something else will go next month, treat yourself to an early Christmas present. Peace, to you and yours, Gym

My projector goes blank every one minute


This is most likely the lamp. Replace the lamp and then in the setup menu you need to reset the lamp hours to zero. If you have replaced the lamp then you need to still reset the lamp hours to zero. If you do not it will never stay on longer than that hour. If both of these have been done and it is still doing this then it is over heating and this could be caused by lack of air flow (clean filters) or a bad power board.

Tip

Buying Projector Lamps/Bulbs


Be careful on buying the cheapest projection lamp. When lamps are made for a certain projector manufacture the lamps sent to them pass a certain quality threshold. Some lamps that do not pass the quality requirements are sold to independent vendors. A lamp not bought from the manufacture may not last the hours you expect from it.

If after replacing the lamp it did not light up.


Hi,Sometimes after replacing the lamp on their DLP or LCD people still keep getting the red lamp indicator or simply it doesn't light up.Most of the time people forget to close the door cover of the lamp area.There's a switch that's pressed when the door is full shut,if it's not pressed it will not let the tv light up for safety reasons.Another reason why it doesn't light up or keep getting the lamp indicator is because it needs to be reset it,for most tv's what works is to unplug it wait 5 min and plug it back again.For some Mitsubishi models they have a reset button you can press and that will do the work.Other brands have reset procedures like holding the menu button while pressing volume button etc.After you've done this and still doesn't light up you might be experimenting the most common failures like the ballast which is the board that powers the lamp.When the ballast is to weak to power the lamp it might light it up for some minutes and then will shut it off.The procedure and cost to replace it is easy and low in repair cost.This is something you can do your self,most instructions are on youtube.

This is most likely a problem with what's called "HDMI handshake." It's a silly protection scheme called HDCP that is meant to keep people from copying content. The best thing to do is unplug everything, then turn on things in this order: receiver>projector>sources (directv, Bluray). If that does not work, check for firmware updates for the receiver or projector.

The speakers will still need their electronics to operate from the audio source.

Proprietary connectors are a clue that the base and the speakers are a set not to be mixed or matched with standardized audio components.

Dwin transvision 4 projector lamp will not light even after changing the bulb. It also looks like Dwin went out of business. Any options to fix?


Call Interlight @ 219-989-0060 and read them what the part # is on the bulb inside the cage. They can probably supply you with the lamp and you simply reuse your cage.

They were able to do this for me

How do you tell if the color wheel or the cooling fan is out


That would be the color wheel. They range from $150-$600. That sounds like the whole light engine could have went out. They can be rebuilt for around 750-1000 bucks.
