Hello, Since I terminated my LG service contract I am getting rid of my stock. As I no longer have access to the LG Technical web site I see little point in dealing with them. What i have here are boxes of optical jack sockets bought for refurbishing LG sound bars. Until LG got them in stock these were not available except from CHS, and they went bust. Looking at selling the lot, they do fail a lot, not electrically but the door on the front is so fragile. That's why I bought 500 at a time. The trade price was £4.04 each. Open to offers, don't be shy of making a silly offer. I just want shut, they are new and add quality to soundbars that have their ports broken. It is a very common problem with LG soundbars.
