Philips 50" TV Slow Start-up and Poor Performance

I had a lot of faith in the Philips 50" 7600 series TV that I had purchased from A101, so my expectations were pretty high. On the other hand, ever since it was installed on July 24, 2023, turning it on now takes a full quarter of a minute, the volume control is laggy, and switching channels is excruciatingly sluggish. The way it has been performing has completely failed to meet my expectations. It is my intention to send it back and request a refund. The performance of the television was not even close to what I had hoped for, and it did not make me happy in any way. I am unable to give this model my recommendation to anyone.
