LG 2300W AV Receiver System amplifier

We purchased the LG 2300W AV Receiver System, which will be two years old this December, and have unfortunately encountered recurring problems with the amplifier.

Initially, the system would power on, but the display lights would not work. The following day, everything appeared to function normally. However, shortly after, the amplifier stopped working altogether. Despite multiple troubleshooting efforts on our part, the issue persists, and we have not received any support or assistance from LG in resolving it.

This has been a very disappointing experience, especially considering the significant cost of the system. Upon further investigation, we've also noticed that many people on Facebook Marketplace are selling their speakers without the amplifier, as it seems the amplifier is frequently deemed non-repairable. It is clear that many customers are facing similar problems, suggesting this may be a manufacturing defect.
