So the boss gave me a tv to ummm...get recycled lol

We can't sell it in this condition and we've sent it out for repair but the technician replied that there was "nothing electronically wrong with the unit, seems something was dropped on it.."

the boss says its dead pixels since its too much of a perfect circle to have had something hit it.

I am just wondering if its fixable?

It doesnt bother me or the girlfriend, most of the shows we watch are widescreen so you barely notice it

A dead pixel usually manifests as a much smaller object where it is either stuck (which is sometimes fixable) meaning it always displays the same color, or it is really dead, in which case it will usually display as black.

In this case, given the much larger size than you would typically see for a dead pixel plus that "halo" of bluish light that's surrounding the dead zone, usually indicates something other than a dead pixel.

Something that large is usually caused either by weight (ongoing traumatic impact like someone kneeling on a screen or leaning the face against a heavy object, but not fast enough or with enough flexing force to actually crack the screen) or by water damage (spraying it with window cleaner or water).

If it's weight damage, it depends on exactly how bad it is, sometimes you can massage the LCD liquid layer back in place, but more often there's internal damage to the LCD layer or one of the polarization layers that means you'd have to replace the screen.

If it's water damage, you might see the circles disappear and reappear or migrate to different places on the screen. If that's the case, you can try running it for a while to let it get warm then bag it up with a desiccant like Silica Gel. If you can't get an actual desiccant, rice is ok but doesn't work quite as well. This works if the water is close to an outer edge and depending on how well your TV is sealed, otherwise you need to separate the layers and dry it out. If you don't know what you're doing there, that can go downhill real fast.
