I write to see if I can get any support within an "experts" forum, as I really don't know what to do with my projector.
I have been a happy owner of a Sony VPL-HW40ES 3D projector since March 2015, but in the last few days I have been experiencing a very peculiar issue: screen seems to be perfectly split in two halves, with one of the two being darker than the other.
This is not fully evident in all images and all motion scenes, however the difference between the two halves becomes unmistakable to notice whenever a full "monocolored" block is being projected (e.g. a bright red). The line splitting the two halves seems to be perfectly vertical, appearing in the middle of the projection area.
I have been surfing a bit the web to understand if the issue is common or could be related to the lamp, however:
- My lamp should still be relatively effective (current lifetime: ~1000 hrs)
- Problem does not seem to be linked to lamp efficiency, or to "common" signs of a lamp getting near to "end-life"
Can anybody provide some direct experience or support?
