I have an optoma HD81 projector that is 4 years old. It shut down and now a red and blue light flashes on the projector. I changed the lamp same problem. I have powered down. I also disconnected and reconnected rs 232 cable. no change. Finally, I unplugged the hdmi cable from the back of the scaler and I get a black and white vertical lines across the screen. Plug the HDMI back in and red and blue lights flash and shut down the scaler instantly. Any ideas? Eric
