Well, my 5020UB with a whopping 700 hours on it has finally stopped really working. When it first starting acting up, I had a Harman Kardon receiver connected to it. First it would not sync, so I tried an HDMI splitter I had lying around, and as mentioned elsewhere in this thread, that fixed it, for a while. Next, the HDMI 1 port stopped working, so I switched to HDMI 2. Finally, even with the splitter, I could not get video. I realized that the HDMI out on my Harman Kardon receiver was dead, so I figured it was just that, so I chalked it up to that and got a new receiver (Onkyo). Even with the new receiver, HDMI 1 on the 5020UB did not work, but HDMI 2 worked fine, and I didn't even need the splitter, for a while. The problems started like they did the the HK, where I could not get a signal without adding a splitter. Like has been mentioned in other posts, if I directly connected the source to the 5020UB it would work fine, but would not handshake with the receiver. Furthermore, I could only get 1 source (Media Center PC) to display a picture. With other sources I would get a black screen. My 5020UB was also acting up like others have noted where it would turn on and the fan would run at high speed for several minutes before finally displaying a picture.
I have no official proof, but it seems that somehow the 5020UB is killing HDMI outs on receivers: it seems like it did on my HK, and is currently trying to on my Onkyo.
I just got a new projector (Not Epson) and it works fine, so hopefully my receiver survived! I just needed to vent as I am very frustrated by my 5020UB. Off to the landfill for it?
