Just an update on the saga with my RS40. So I resolved to live with a single HDMI input and use an HDMI switch to get content to the projector. That worked fine for a day or two, until last night. When I turned on the projector, the lamp did not light up, and the unit would not project. After a minute or so, it went back to standby, with the warning light a solid red, and the lamp light blinking orange. I looked up that pattern in the manual, and it said, among other things, to check the lens cover. I saw that the automatic lens cover was not working, so I took the projector down and attempted to open and close it manually, using the little button at the top front edge. Eventually, I got the lens cover to work, and happily, the lamp to come on. I tried it about a half dozen times, all successful, before I rehung the projector.
Then tonight when I turned on the projector, I had the same problem again: the lens cover would not operate (seemed to be stuck mostly open) and the lamp would not light. So again, I attempted to move it manually (all without taking the projector down), and eventually, I got it to work again. I put a DVD in the player and started to watch a movie. Unfortunately, now the image appeared pretty dim. It was just barely watchable, but we decided to watch it anyway. After about 75 minutes, the lamp exploded.
In the space of three days, I saw these problems:
1. Dark red picture on HDMI 1. When I looked at the HDMI port, it did appear that the pins on one side might have been bent or damaged.
2. Failure of the projector lamp to light; related to
3. Failure of the lens cover to operate automatically.
4. Dim image.
5. Exploding lamp.
Obviously, I am now going to send the projector in for repair. I could just get a new lamp, but I think more is wrong than that. But I wonder: are all of these problems related, or is it just coincidental that all happened at the same time? Any insight would be appreciated.
