Don't buy any LG Smart TV

I purchased an LG Smart Television approximately 3 years ago. 65" OLED TV at a cost of R27,000. After about 3 months the TV would display a message in top left hand corner 'Unknown device is disconnected'. I thought it was related to my fibre connection, the message would appear intermittently but got worse over the last year. It would appear every 30 seconds....I googled the problem and found hundreds of articles and YouTube videos from all over the world that this is a massive issue on LG Smart TV's. Google yourself before purchasing any LG TV. I called out a technician and he knew exactly what the problem was and fixed it by replacing the WiFi module in the TV. The cost of repair was reasonable but I had to pay as the TV was out of warranty. This is a latent factory defect and LG should be aware of it...when you phone the call centre they have absolutely no idea of this issue. I had to explain that they should be pro-actively dealing with this blatant factory defect. Send 2 mails on the LG Care line and have not had the courtesy of a response.
