Mitsubishi WD-60735 TV doesn't respond to the remote control at all (on, off, volume, input, etc) and has to be powered on and off manually at the control panel of the TV. Volume menu is stuck on screen but picture and cable work fine. the remote control has been replaced with batteries, does light up when buttons are pushed and ensured volume button is not stuck. i have tried pushing the system reset button twice on the control panel, unplugged the tv and waited 1 minute, pushed menu and format at the same time on the control panel but nothing works, the volume menu stays on screen and the remote for the tv does not respond to any commands other than to light up. any suggestions?

Check owner / operator manual for "panel lock" selection or
go through menu pages until you spot it........
This selection is made so guests or children cannot operate tv.
In case this suggestion fails, you might try hard reset = unplug
AC cord overnight,then try again...........T.

Looks like the core of the problem is this:

microswitches on the frontcontrol board leaking.replace it.
http://www.fixya.com/support/t2422987-same_problem What worked for me was this: Supposedly, the front panel is known to have leaky switches. power,volume,menu,etc.. They asked me to take my finger and rub left to right back and forth hitting all the buttons, do this about 20 times.. then poke the reset button in and out a few times.. Wait about 60 to 90 seconds and see if your green light quits flashing.. If so, try powering on with your remote.

Sounds like a bad color wheel.

With the remote press menu 2470 enter then do a system reset after the set has reinitialized this should fix your problem, you will have to reprogram your channel settings afterwards though.
