1. The sound quality is not very good. Even if you press the volume button all the way up, it doesn't get very loud; it just gets distorted, and, badly, at that. And, on top of this, the only way that you know that the volume is changing is by a line on the screen that increases when the sound is turned up and decreases when the sound is turned down. That might not sound like such a bad thing, but you can't really quantify what level it is on just by looking at a line.
2. The color! The controls for changing the color can only be accessed one at a time, so, when you make a change in one, you have to go back into the menu to make a change in another one. It would be much better to be able to access them all at the same time, so that you could make adjustments as needed without all of the hassle.
3. The menu - it's just way more convoluted than it needs to be. I'd rather there were one screen that I'd be able to pick from than to have to go through 5 different ones to try to find what I'm looking for.
Shoot, maybe I should have given this TV a lower rating, huh?
