I have lost both inputs... I was having issues intermittently with input 2, the signal would drop out. I replaced cables, then input 2 stopped working altogether.
Then after about a month input 1 did the same thing, now I just have "No Input" on the screen...
The menu displays fine, but no matter what I plug into the HDMI ports I get nothing.
I moved a dvd player on a ladder with a known good short cable, did factory reset, I flashed the firmware, and I pulled the covers and reseated all the connections to the input board (processor pwb assy), but still nothing...
I am assuming that processor board is the issue, but I don't have a service manual to do any diagnostics. There are led's on the board that I'm sure would help with troubleshooting. I feel like power is good since everything else seems to be Ok (bulb, menu settings, etc.).
Does anyone have troubleshooting info for this board? Has anyone replaced this board themselves? I took it out, but did not see any burned or damaged components.
Has anyone else run into this? I searched this thread, but didn't see anything. It's a great projector, and I'd like to fix it even though I just replaced it with the X770R. The processor board is about $750 if available. I'm willing to put that into it, but I'm not sure paying that plus shipping to menditronix and repair hours is worth it.
