My guess is that it is not economical to fix as it needs new screen. Unless it's under warranty but then you would not be asking. I had an off brand tv that I sold at my Radioshack franchise year ago. I had a customer get a tv with one white pixel constantly on. I replaced it for him. When I called the mfg, they informed me that this was allowable error in the b grade displays they used in their TVs. I quit selling them and put the bad one in my Rv. Still ticked me off when I watched it
