Does your bed temperature reads correct at room temperature? If so, then I think you needn't to run this commands.
What's your bed type? Is it MK2A or MK2B? You can refer to the link here to check the wiring of the bed:

And download the latest firmware for your printer here:

For the LCD, check the pin12 and pin13 of the mainchip, see if there's solder bridge or something make them shorted out.

sorry, I made a mistake, forget about the pin12 and 13, it's not this two pins, it's the pins in the SD card slot, see if it has bridge. you can check the picture I updated above. also you can check the back of the LCD board too. And what's the resistance of the hotbed(remember to minus the resistance of the multimeter)? if it's larger then 2ohms, then the resistance it too big.
