Just over a year old now is our 55" LED Smart TV which has got bumped when walking past one too many times. Even though it was caught before it fell completely off the TV stand it obviously got shocked somehow and now has a number of grey stripes running both vertically and horizontally. Maybe you have the skills and knowledge to repair it or can just make use of some components to repair other electricals. Otherwise It will just be going to the dump. Seems a shame. It is a 2023 model that we bought early 2023.
