Hello,
our Institute purchased a Discovery 4000 Developer board in 2009. Since some time, we are seeing artifacts on the DLP chip. Vertical lines appear on the patterns displayed. The artifacts change a little over time and are not necessarily effecting a whole column on the chip.
After contacting the local distributor, we were told that the board has a production error and was replaced for free in 2009. Unfortunately, we were not informed of this opportunity. Is it still possible to receive a free replacement?
Regards
Steffen Matthias
