vizio model sv470xvt1a no pix but chirping sound

Had this tv now for a good 8 years maybe a longer. Just the other day out of the corner of my eye I think I saw it flash and when I looked the screen had gone blank and there was a chirping sound. I did notice a light on near the bottom speakers. I unplugged the tv and all the things plugged into it and left for the afternoon. Tried plugging in that evening and the the screen still remained blank/black and the chirping started. No light near the speakers now?

Anyways just wondering about how to fix this issue and what the replacement part is? I’ll look into whether or not it is worth me fixing it or just getting a new tv?

Lol tried contacing Vizio and the customer support is a joke. If I do get a new tv it won’t be Vizio
