My TX-T3093WH tv has a bend on the left-hand side of the screen. Recently, a repair agent came out, entered in a "master code" for my television and was able to adjust this. The repair agent came out because I noticed this bend while watching television. He corrected; however now when I play videogames, the screen still has a bend on the left. Does anyone know the service code to enter to try to adjust this? I have tried - power off, mute 1-8-2, power on, but I was not able to get access to the options he had displayed earlier. If that's the correct code, I am more than likely not performing the action correctly. Please help! Thanks!
