Flashing LInes across my screen...

This problem just started a few weeks ago out of nowhere. When i change the projector to my input source (direct tv) it gets lots of flashing horizontal lines across the screen that make veiwing almost impossible. Ive checked all the cable connections and they appear to be fine. Ive also installed several interference blockers to no avail. The problem came out of nowhere and i cannot figure it outl.

ANy suggestions??

Projector powers up as normal, bulb comes on, displays Optoma logo on screen and menu will show on screen. The issue is that although I have 3 devices plugged into the HDMI port of the device using a HDMI...

There is a source lock and source button I would unlock source lock button and the push source button until you get to your hdmi input you are using. You also may just plug in one input first and once you get the input right play with the multiple hdmis

I have a Optoma EP721. It now projects verticle lines on the screen background. How do you eliminate the verticle lines ?

It sounds like you have a projector which is in need of professional repair. You should eliminate source material problems first though by checking the projector with alternative input sources, ensuring that you also check the cables, and various inputs on the projector.
If the lines are present on all the inputs then the fault is internal to the projector. This will require professional repair. The first point of contact should be Optoma at (UK) or (USA). They should be able to give you an idea of ow much it may potentially cost to have your projector repaired and (most importantly) check whether it is under warranty. Most Optoma projectors ship with 3 year warranties these days.

Screen is turning a pink/purple colour


You should firstly test the projector using some alternative input sources, and using different cables to establish that the pink/purple tinge is consistent across all inputs.

If it is, then your projector is in need of professional repair. You should be able to contact 3m here who can advise who their local repair agent is.

Best of Luck

Multiple reddish pink vertical lines going from


We can check if the problem is on the hardware(projector) itself or if from source(device connected to projector) try to turn on projector without connecting any other devices to it. If you can still see the pink line- try to remove bulb and reinstall it. If all fails and pink line still visible, there is a problem with projector. If no line is present- check settings and change input signals.

Hope this helps

Proxima Ultralight x350 no valid input source error?

reset the settings to factory default. if that doesn't work, the lamp may not have enough power to stay on. if the lamp doesn't have many hours on it, it's the ballast.

Discolored image and lines...

I also am having the same problem. at first it only showed up after the projector was on for about 15 minutes. Now I get a purple vertical bar on the right of the screen. I also get vertical green bars spread across the screen.
Does anyone have a diagram of how this machine is assembled?
