What the heck is wrong with my TV?

[Quiet Stranger]

Okay so when playing my PS3 on my Sony Bravia HD tv (The TV is a few years old now and the PS3 is near two years, the TV is older than the PS3) the TV makes weird buzzing noises and the sound kind of comes in and out. I've tried two different HDMI cables and the noise still happens. Do I need to get a new TV or a new PS3? If it is the TV can it be fixed or is it more worth it to get a new TV?

Sounds like you may have a damaged port on your TV or PS3.
Try a different port on your TV (if you have one)or give the cable a little wiggle at both ends. if you notice a change in pitch from the speakers it's most likely the port that is damaged.

Does it only happen with the PS3? Does it do the same thing on different TVs? Testing a few different things will definitely narrow down the problem source, don't be hasty or you might end up replacing something unnecessarily.

If you're on a power strip try plugging something direct into a wall outlet or experiment with a battery backup. The strangest things can start humming, like even a generic USB wall charger.

Asymmetry in the line voltage will cause any transformer to buzz like crazy and anything with a half wave rectifier will do just that. Since the Smart-UPS has a rather large transformer, the effect will be very noticeable. Two step lamp dimmer, overhead projector and hair dryers are notorious for that. If there are overhead projectors or two-step lamp dimmers, try turning them all off. If this doesn't apply to you, have an electrician come out to test your power line for 2nd, 4th and 6th harmonics.

If you don't have anything like that in your building, then it is possible that someone has a three phase motor drive with a failed component causing a DC offset on your line.

This goes for you too nicolen. I did notice your profile say you're on behalf of "CK Manufacturing and Trading, Inc.". Perhaps you have some large VFD motor drives within the building.
