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

There is a purple image showing even when there are no cables connnected. Is this something wrong with the optical engine? I read this somewhere.


If the entire image is indeed purple from corner to corner uniformly, I'd say maybe one of your lcd ribbon cables is not plugged in all the way. BUT--- if the purple is like a blob in the center but not quiet spreading out to each corner, one or all of your lcd panels/polarizers in the prism assy is burnt and the prism assy will have to be replaced. Very expensive.

The projector shows slides as purple but computer has the right colours?


Check your cable...you are missing one of the primary colors. you could have a bent/broken pin on either the projector port or the cable or laptop port. this would be the VGA connection.

Hi Sue, On your first concern, a possible reason for the 'Sync is out of range' is because your laptop's resolution is just too high for the projector to handle. You may have to manually lower down your screen resolution (right click on a clear area of your desktop, click on properties, settings tab, move bar of screen resolution towards the left). Try different settings that will give you best performance without the projector rejecting the input signal. Am not sure about your second concern though, offhand your description sounds like video noise. You may have to check that your connectors are firmly plugged in. A longshot is to remove any possible source of interference like wireless phones including your mobile, WiFi AP and the likes. Perhaps you give the first suggestion a try and see if the purple dots disappear when you have the projector running ok. Further you may have to reset your projector if it's got one. Normally it's a small button clearly marked RESET somewhere at the rear of the unit. Hope this works out for you. Pls comment/post back should you need further information. Good luck and kind regards.

Projector Colour Problem


Could be a few things....first you need to isolate a signal source issue or a faulty LED lamp. Simply unplug your signal source and run the menus on the projector. Purple Gone with source unplugged = faulty source our signal Purple still there = faulty device Sounds crazy but make sure you have no interference devices running real close within say 2 feet. cell phone, microwave, magnets, high voltage eletricity...etc
