The unit is stuck on "upgrade" on the display panel. I have unplugged several times and it now will not even switch on. How do I fix it?
Maybe you need to upgrade the firmware driver or software to the latest version..go to LG website to get the latest versions for your model
SOURCE: the disc is stuck and the display reads "No disc".
Ok one easy fix to this is to tilt the player while the system is on whilst constantly pressing the eject button. I once had to even turn the whole thing upside down then back and shake a little until the disk positioned itself properly to eject. good luck

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
The 'LE' error message indicates the control board has detected that the motor is either not turning, or has locked up for some reason. Monitoring the motor is the job of the hall effect sensor board which constantly determines the direction and speed of the motor and feeds that information back to the control board. If there is a problem between what the motor should be doing and what the hall effect sensor says the motor is doing, the 'LE' will be displayed and the cycle will be stopped. Step 1: Unplug the washing machine. Step 2: While the washer remains unplugged, press and hold the [Start/Pause] button on the front panel for 5 seconds. Step 3: Plug the unit back in, and run a rinse and spin cycle to test if the LE code is cleared.
Motor lock can be caused by several things from a loose connector, to a bad motor, or even the hall effect sensor failing or dislodging from it's mount. Any one or more of these components could have caused this error.
This error can sometimes present because of a miscommunication between the control panel and the wash motor. In this instance, the washer simply needs to be reset.
