The TV was fine today but then I noticed the volume control wouldn't work. I turned it off and now it won't come back on at all. Electricity is fine, plugged in, etc. Maybe the cord? Do they just die like this?

Ur Main Fuses in the circuits breaker box must be to be restart it back.Turn off/on all the fuses on the main circuits breaker box to all the fuses in the box of the box to restart.All ur electical power outlets should work again.If not those power plug in outlets are shorted and dead must have to be replaced.
I'm pretty sure that the buzzing sound is a not normal thing for an LCD TV. I sell Flat Panels during my spare time and it should be as quiet as a CRT types. It is more likely a defect and you should return it ASAP.
Hope this helps.
my 46'' inch tv polaroid lcd has been working fine for 3 years. today my wife and I noticed the tv is shutting off the screen will go black and the power light does switch to red. you can here something inside the t.v clicking but you can turn it on and it will start back fine for 20 minutes then shut off again? Does anybody know whats going out on the tv? let me know
Also had the same problem with our Panasonic 50" Plasma...could not change the channel or the volume (with the remote control nor with the actual TV controls). Before I called for repair, I UNPLUGGED the TV and then plugged it back after a minute. I was surprised....the TV started working again. (Switching the TV on and off is not sufficient). I could change channels and volume, etc. So this saved me a repair this time. Might be worth trying this solution. Wouldn't hurt one bit, but rather save you a repair fee.
Same problem with my set. The volume was either fully up, or fully down (usually down), and other controls didn't work- like I couldn't access the menus and could not adjust the width of the screen/aspect ratio.
I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.
I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.
