I'm a new member of the forum so please forgive me if I've posted this inquiry incorrectly!
My 65HM167 is nearly 5 years old and for the first time it developed white dots, 8 over a one week span that started just after Christmas. Tonight I replaced the DLP chip and not only are the dots gone but the image is just as sharp, and the colors as vibrant, as when the unit was just out of the box. I was fortunate to not experience many of the post-chip replacement issues some folks seem to have had. However, I am having an issue that I haven't seen mentioned and I'm hoping someone here might provide insight. Basically, when the image is completely dark (or when tuned to a blank screen, i.e. an input for which the corresponding device is turned off), the upper right corner of the screen is, for lack of a better term, lightened. It's almost like being in a theater and someone opens the emergency exit door, as if there is a dim light shining on the screen. It's not some source of light in the room, it's "under" the surface of the screen. Although I was extremely careful in re-assembling the unit after replacing the DLP chip, I suppose it's possible that something is not properly positioned and some light is seeping through in a place where it should be contained, but I don't want to open the set back up and start poking around/retracing my steps and make the problem worse, or create new ones. It's very mild but certainly noticeable, and I thought some guidance from folks here might help me to isolate where I should be looking and/or placing my effort. Any help would be appreciated!
Thanks to all who posted on the DLP chip replacement. Between this forum and the helpful YouTube videos, resolving the major issue (the rapidly proliferating white dots) was really quite easy and rather affordable. I just hope to correct this new issue that emerged following the chip replacement.
