My projector has lines on the screen. new bulb didn't help


If this projector is connected by Component Video (3 or 5 wires) instead of HDMI, the most common color related problems are caused by having one of the 3 video cables (Red, Blue or Green) with a bad connector. If everyone is a green smurf the problem is with the red cable. If everyone is a red smurf the problem is the blue cable. If the green was bad you wouldn't see anything.
Another possibility is if the green is plugged into the yellow jack instead of green jack on the projector, you could see what you are describing.
If everything checks out, take the projector to a repair facility.
If you are connected by an HDMI cable, (combined with the fact you mentioned vertical lines not horizontal) then take the projector to a repair facility.
All of this assumes that you don't just have a bad Cable Box or Blu-ray player or Home Theater Receiver. (The source)

Image is upside down on the screen


Alot of projectors (being all projectors that are designed to be hung from a roof) have an image flip function. This is because when you install a projector in a roof you have to flip the projector upside down so the projector doesn't have to be pointed down and doesn't cause any problems with keystoning.
If you have just bought a new projector and installed it in the roof or perhaps bought it second hand and are projecting from the floor (when the previous owner may have had it in the roof), you will need to go through the menu screen until you find this setting. I don't know exactly what Epson call this function but it should be in there somewhere. If you have it on the floor you want image flip off, if you have it in the roof you want vertical image flip on, horizontal image flip is for when your projecting onto a special screen surface from behind the screen.

Image is bright but there is a slight issue - on the left hand side a purple line displays vertically. Anybody knows why is this fault appeared and how could it be solved.


There is three LCD in the projector red, green and blue. If green LCD make any fault mean line or dot or dots then screen show these line or dot in purple color:
If line is very straight and sharp edges then green LCD is faulty and need to be replaced.
If line is not straight and faded edges then some thing in LCD block so your projector need service

Thin vertical line appears on projector


I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.

Vertical Green Lines


Hi Jon

Check if the lines shows on both PC & Video inputs. If it shows on both you could be in for a new Mainboard.

If it only shows on the one signal and not the other it could only be a loose connector that needs soldering.

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?
