Well my tv is back up and running from after the light engine has been replaced. So far, it has worked well. I still had the intermittent 3d issue, so I reloaded the 2010 companion software then the 12.08 firmware just for good measure. (not sure if that help or did anything at all) I did watch one 3d movie after reloading and it did come up correct, I may of got lucky.
My recent problem was it would black screen then go back to the input then go black again. It only did that when right when it was powered on and only happened twice. So far the problem has not returned.
Things I have noticed after the LIGHT ENGINE has been replaced:
1- The installer may of installed the housing a bit off. The picture has lost about 10 lines of horizontal res on the bottom and about the same on top. I figured that out when I went to resize my picture on my computer to compensate for overscan. I am currently on 1824 by 1026 to get the whole pic to fit the frame. Its less res then I used to get. I still have a little of geometry issue but Im ok with that. I have a feeling that a mirror and or tv frame is the culprit and I dont notice it during movie veiwing only internet veiwing.
2- I have not seen any intermittent "flickering" at the top right of the screen after the light engine replacement. Again this was only noticable when internet viewing with static white images. kinda like being on this website at the reply section.
3- My favorite issue that has lessened was I do not see the "rainbow" effect of the DLP color wheel as much. Not everyone sees that and I knew this before I bought the TV. I guess the timing with the chip and the color wheel can differ from engine to engine. This positive makes me forget all about loosing some resolution.
So far a descent experience. Now my TV is officially out of warranty. crossing my fingers for a good, long lasting mainboard and engine.
