I'm expecting the same answer I usually get regarding questions. While this TV (Sony XBR-65X850D) is 8 years old, it displays a great picture and performs when using external streaming devices (FireTV 4K Max, FireTV Cube, & AppleTV 4k, all the most current models). However, a few minor blemishes or minor scratches are mostly unnoticeable. Any suggest repair or mitigation solutions? I want to keep this as my second TV for quite a while! TIA
