DLP Image Issue Help (1 Viewer)

Hi, I'm looking for help diagnosing an image issue that just popped up. I have a BenQ HT2050 DLP projector, manufactured in 2018. About 2 months ago I replaced the bulb and cleaned the inside of the unit. It was very dirty as it had never been cleaned and there is a pellet stove in the same room. After the cleaning and bulb replacement the image was great for weeks. Then recently when we turned it on the image was suddenly quite degraded. Reds look more pinkish and any white/light areas have pink/reddish hue. Faces and other lighter areas have red and green bands. I've included pictures that I hope convey the issue. I thought it might be a color wheel issue so I replaced that but it didn't improve anything. I also swapped out the bulb with an older spare I have and again it didn't improve the issue. Hoping for some guidance on what could be causing this. Thanks!
