My Mitsubishi 65" rear projection TV turns on with the device menu on the screen and it is continuously highlighting or selecting the inputs, but does not change them. The TV does not respond to any menu selections, it jsut keeps scrolling through the inputs. I fixed this once by pulling the input card from the board and powering up the unit which I assume caused it to reload the input software, but that only lasted a couple of months before it started doing the same thing and now pulling the input card does not fix the problem. Any help would be appreciated.
I tried the air trick but no success. I took the boutton PC out
examined it, tryed it sitting out of the casing still no success. I put
it all back together plugged it back in and Wha- la it worked good as
new. I am not sure what changed but I thought it would be good info for
anyone else that sees this problem. You gotta love the intrnet.

Many thanks!
We just fixed our Mitsubishi with a clean empty plastic bottle that blew air onto the front panel buttons and fixed our same problem as you described. Hope it stays repaired!
Thanks again as we were stumped as to the repair.
Did you try resetting using the RESET button on the front of the TV? Also what "input" card are you pulling?

Yes. I've tried both the reset button on the front of the TV and also a hard boot without any luck.
When I got it working the last time, I pulled the ASSY-PWB-2HDW board and power the TV on without that board. Next, I replaced that board and pulled the ASSY-PWB-3DYC/MD board and again power on the unit. I replaced that board, powered on the unit and everything worked, and has been working for about 4 months and then it started the same device menu scrolling when my son tried to change imputs from DISH to PS2.
Fixed! I found another post where someone had a simular problem. Seems as though I either have a stuck "Device" button on my remote or the "Device" button on the front panel of the TV was stuck. I pulled the batteries out of my remote and cleaned the front panel buttons with air pressure than moved the buttons on the front panel, with pretty good force, to see if they were stuck. When I forcebly pushed the "Device" button the menu quit scrolling and I was able to make device changes.
I'm not sure how pulling the boards the first time fixed it except we were pushing the front panel buttons at the same time and probably un-stuck the button at the same time we pulled the boards.
I had the same problem, the remote was not working at all; but I can use the TV buttons to turn on, and it stayed on one mode (device mode) only, can not use the Device button to made changes.
I fixed it by using AIR DUSTER to blow the Device button from outside to clean it. After that, everything works normally. My remote also works.
I just had the same problem after coming home to a cold house (64 degrees) after being away on vacation all week. I used compressed air on the input and the right select button, at it worked!!! Thanks for the help everyone above!! (set: MS65611 - 6.5 years old)
