I seeks some help and suggestion fixing my Infocus IN82 DLP projector. This issue affected many users of the Infocus IN80/IN81/82/83.
The issue is dicussed in detail in the owners thread here
Infocus X10/ IN80 Owners thread - Reviews, Settings, Screenshots and issues
In summary, after few months of use, the image shows up murky and blotchy colours on dark skin tones or red / green tones. Initially it affects dark scenes with mostly red tones, but later it stars affecting al colours even in bright scenes.
The exact reason is not fully understood in that thread and Infocus is not going to fix it out of warranty. In my case Infocus replaced 5 units on the same defect, but they never fixed it or bothered.
Here's what is found in most cases on this particular issue
1. Initially starts with posterised red and green tones
2. On turning Brilliant color on - it goes away (not sure why)
3. After some time turning on BC reduces the issue greatly but not eliminate it completely
4. With more time the issue becomes worse and even with BC on it becomes unusable
5. Initial 2-3 min of turning on the issue is not visible, but shows off after that - heat??
The projector without the posterization issue is excellent, but not usable now as it affects the image too much now.
The reason I am posting this here is initially I thought it was affecting mostly Infocus In8X range, but later saw some other sites where people have reported similar issues on Optoma DLPs as well. I just thought posting here may get me and some owners some help from a wider DLP community.
I'd appreciate if anyone can help with the issue and if you ahve faced something like this, what you did to get rid of.
Buying a new PJ is a easy choice, but I am not able to just throw it away without giving it a try to fix.
Here's a couple of files with both BC off (see issue with red and dark skin tones) and BC on (issue gone or reduced)
