That is a system error related to the automatic focus and since it is caused by a failure in the integrated components of the camera, it needs to be sent in to be fixed (i.e. the camera replaced under warranty) Call 800-706-2534 and keep choosing option 2 and they will tell you where to send it.

High pitched noise is from a very high CO2 level. Adjust the gas pressure to stay above 11" w.c. and have a gas technician with a calibrated CO2 analyzer adjust the CO2 levels.

if the speakers are built in try a new rca cable

call an assistance to your technician...

The mainboard might have some loose components, or cold solder , or may be the filter capacitors are becoming faulty. Yes it is worth repairing, bring it to the repair shop. Cheers.

The LE error code means that you have a motor problem.  The high pitched noise means that the motor sensor has failed and needs to be replaced.  You will need to call a qualified LG technician to replace the sensor.
