a month or two ago i had my lamp replaced under a warranty repair. since i had it back i had noticed some slight problems with it displaying bright images.
two weeks ago i acquired an old but still boxed gretag macbeth eye one display 2. after having a go with calibrating the projector i have noticed the problem even more.
i reverted back to the the out of box settings due to this.

maybe i am noticing the problem much more as i am looking for the problem but now i see it clearly with the out of box settings aswell.

HD65 image

same again close up

heres the same image on my panasonic plasma running on the same hdmi connection.
BTW the pause icon shows a different reading each time as my skyhd box displays how long the pause has been activated for

the artifacts look much worse than shown in the images.
maybe its an issue with how its processing the colors? when i project a gray scale i find that it adds a tint to one of the lighter bars which shifts to another one if i change the rgb settings, or brightness and contrast.

any ideas on whats going on guys??

i am contemplating contacting optoma...

thanks prof! i have contacted optoma today.

i have noticed that you are interested in the HD65. i wouldnt let my experiences alter your decision too much as i seem to be in a quite small minority with regards to issues.
and the problem you see is only apparent on the odd occasions when viewing.

leonard - if it were a build up of dust, would i not see the artifacts all the time?:scratch: i am only seeing them with certain white images.

it seems to me that the projector is not processing the info sent to it correctly and hence projecting a different color.:dontknow:

BTW the artifacts are well delineated like rectangles and squares if thats any help. i'll try and get some clearer pics posted

photobucket is altering the resolution causing my pics to blur somewhat.

optoma are taking the unit back in for inspection tomorrow.
i also asked for a loan unit while they fix mine and they obliged :T

 

[custard]

That's pretty good service..:T
I doubt they would do that down here..

optoma offer a 3 year hot swap warranty at no extra cost in the uk. i only realised this after reading of a positive experience that someone else posted.

i had my projector back of optoma today.
the receipt that came back with the unit lists that the lamp and driver were replaced again although they were already replaced a few months ago. the noisy fan was also replaced.

anyhow whatever work was carried out does not seem to have sorted the problem. the artifacts can be seen in different scenes. i'd explain the issue as something similar to what was seen on some older panasonic plasma models referred to as purple snakes - the units would not process the color information as they should resulting in the wrong color being shown.
i'll post some further pics to show what i mean.

as i saw this problem with the loan unit that was sent to me aswell i have decided not to pursue any further rectification.
maybe my expectations of a budget projector are set way too high. it does have alot of other plus points on it side.

prof - i did test changing the hdmi wire without any joy.
