I have a apex 32-inch tv model (AT3208S), This tv was connect to a converter box, the other day electric power went out in our area for about 8 mins or less, once the power was back on the tv screen was blue and have remain this way. I have disconnect, scan, unhook, chg to 3/4. I went to Best Buy, came home a connect, with the same problem. I called Best Buy Tec support, they tried different things, reset, unplug, disconnect ect, same problem the tv screen still blue. The tv is working and the converter box is working. What else can I do.
