Philips 75-Inch TV Screen Issues Return After 8 Months!

I bought a Philips TV that's 75 inches and has a refresh rate of 120Hz about eight months ago. Since then, I've been constantly frustrated because the screen has malfunctioned a whopping 50 times in this short span of time. It's not about things breaking or cracking; the display just starts acting crazy. Sometimes, it just suddenly goes blank, and then there are these weird disruptions that look like a mosaic. I've actually never had these issues with cheaper TVs, which is quite surprising. Even though I reached out to customer service for assistance, I'm now stuck dealing with the actual problem—they're saying I have to take the TV to the repair center on my own.
