Problem with Optoma UHD380x display color
Problem with Optoma UHD380x display color
My DLP projector functioned properly initially, but after a couple of days the reds faded significantly. In Image 1 you can observe the projection on paper since the setup wasn’t complete. The warning message with two lines appears teal/cyan (more green in real life) instead of the expected bright red. This behavior seems to come from the projector software itself, not a signal chain problem. Image 1 originally suggested a potential color wheel issue, so I disassembled the projector and cleaned the dusty color wheel with ethanol. The wheel now appears normal. The issue remains unresolved. Image 2 shows the cleaned color wheel. One additional point is that during the first disassembly, I might have misplaced a sticker indicating how fast the color wheel spins. I resolved this by using electrical tape, though I didn’t recover the original sticker. I’m unsure if this affected color accuracy, but I wanted to note it. Appreciate your assistance.
