    Hi,

    Here is my `Double Picture' story. It started 2 months ago. First a double picture occured. Then the problem accelerated and moved to the next stage: a tripple picture.

    I opened the device with my longhaul screw driver and did some testing.



    First I removed and reconnected the 3 LCD-Panels (Red, Green, Blue) always one by one and in all different variations. But the double picture still remained. So i guess it is a problem in the optical block between LCD-Panels and Lense.



    It is really tricky do to some re adjustments and I am horrified to make problems/conditions worse.



    If you have any Idea please post it.

Most likely the mirror has moved or a lense has come out of its groove.

My Epson Powerlite 5350 has a ghost image. Any recommendation on how to adjust the projector to remove this symptom?


I've got the same problem on two Epson EMP7300.
I believe (from reading about other projectors) that the ghost image can be adjusted with RS232 codes.
Does anyone know how to do this?

My projector shows diferent color, green on the top and normal color on the botom but it shows image


the light polarizer on one of the lcd panels is fried due to excessive dust and heat and will need to be replaced. unfortunately, you cannot get individual parts of the optical engine from philips, so you'll have to replace the whole optical engine.

Ghost image in different color from main image - text appears "doubled"


Use the remote to access the menu and you'll be able to POSITION the colors horizontally and vertically .
You should be able to align with the other colors to make it sync'd.

Epson Powerlite 7300, misalignment of lenses.


By lenses I think you mean LCD panels, and yes there are glue down. there is a chance that the panel managed to unglue it self with time. another thing is you might just have a ghosting image. this indicates a bad lcd panel. What color seems to be out of alignment?
