Hi I have a yellow k in the top left corner of my sharp tv..followed by LC-C40CF6021KB
It seems that you are in Service Mode
This 'K' usually denotes that you are in the 'service mode', and to exit it, you normally just switch off at the mains, (unplug the TV).
If you press 'input' and volume down ('-') together, OR,
volume down '-' and channel down '-' together,
that should take you into you into the service menu proper.
You use channel up/down to navigate the menu, (and volume up/down to alter the values).
You could try this, and see if there's a 'Factory Reset' option if just switching off doesn't work, but DON'T alter any of the service settings (if you use the reset, you will have to re-tune etc.)
