Hi Folks, First post here, I have an Optoma HD200x which is starting to run into a few problems. The image is starting to appear blotchy even with the High Altitude setting turned on. I have the projector since April 2010 and had to send it to Optoma in January 2011 due to the blue flickering issue. They responded that it was a build up of dust etc and this was causing the issue. Of course the lamp hours was reset in January and I believe it was about 1000 at the time...
