Can switch inputs for 65" Mitsubishi

[dsettlemoir1]

TV won't allow me to switch the input for other components. So I can't play a blue-ray, dvd or other device through the computer.

At this time I can only watch cable tv. The picture is great and I am having no problems turning the tv off or on.

Found a number of problems for this tv on google, but nothing about being able to switch to different inputs.

Yes, I have tried turning the tv off and on. Made sure the components are plugged in correctly.

The issue seems to be with the board as I cannot get it to switch to another device through either the remote or the buttons on the tv.

Any suggestions?

Have a local repair tech look at it, unless you just want to buy some parts to swap out, there is probably more than one "board" on that TV to check.
