I have seen issues like this on other manufactures sets needing a software up grade. Mitsubishi deals one on one with customers with software upgrades and will usually send out a SD card with the upgrade on it. This is their customer service number. 1800-332-2119
I hope this helps,

That problem is usually have 2 causes..Its either power supply board or main board..
Please take this steps on how to determine the problem:
Open the back
Check the power
supply output...It should have 5vdc for the main board..12vdc or
16vdc for the audio and 24vdc for the back-light inverter..
If those 3 voltage
supplies have encountered voltage drop...The problem could be on
power supply board..
If the power supply
output is normal..The problem could be on the main board...
If the problem is
power supply you should check if the capacitors are bulged on the
top and try to replaced it..If you can't do that you can purchased
new power supply board..
If the problem is
on main board there is no D.I.Y repair on that so you need to buy a
new main board that fits to your TV..
this solution will be helpful..
Thanks for using fixya...
