Olevia LT 37 HVS HDMI PORT

Question

I had a recent power outage during a thunder storm, the power was off only briefly(flickered off then back on). When the LCD came back on the color on the screen had changed from normal to a predominate black and red color with people figures still visible. This only happens when I turn on my LCD. To correct it, I must open the Menu screen and select the default setting to bring it back to normal again and then reset all my preferred setting again each time I turn on the LCD. My HDMI cable was the only connection from the LCD to the cable box. I have tried a new HDMI cable and had the cable company come and check out their equipment but the problem is still there. Any idea as to what could be the problem and how to fix it, thanks for your input. email: [e-mail]
