Question My portable air conditioner display doesn't work

[aod626]

I have a LG LP0910WNRY2 and the led display does not work but the air conditioner turns on and works pretty good what can the problem be and Everytime I plug in the power cord to the outlet it automatically turns on.

If the device fully turns on (Power led goes green) when you plug it in i would assume it is a hardware fault with the circuitry/maybe something came loose. Did the display ever work and if so did anything obvious happen between it working and not working?

To be honest im not sure a friend gave it to me and she said it works but can't see display but when you push the buttons you hear the beep except the power button
