How does Sharp LCD TV enter the engineering menu and what screen does it use?
The steps for Sharp LCD TV to enter the item menu are as follows:

Press the "power button" in the power-on state to turn it off.

Press and hold the two keys of "Sound-"and "TV \ Video" at the same time, and then press the "Power button". The power button will be released only once, and then release the two keys until K appears, and the item menu appears, so you can see the output of this machine.

Factory time, and press the "Channel+"key to scroll down, you can also view the information on the screen.
