OK, I opened up the projector case (8 screws) and lifted off the front cover. However, I have no idea where the LCD panel is or how to get to it (or even what it looks like). Is there something else I have to remove? I ended up spraying compressed air over the entire units crevices hoping to clean out my projector's dust blobs...didn't work. Any help or link to pictures on how to do this for the L300U would be appreciated.
