Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
Most of the time over size picture signal comes from cable box and rebooting the cable box works to fix the problem. Unplug cable box power cord from power outlet for 5 minutes, replug back in, let it reboot and check picture size.
If problem persist then find a button on cable remote labeled as Format or * or # or Zoom or HD zoom or Aspect or Wide etc, push that button to get different options for picture size and select one to get best fit picture on screen.
Please reply back with the result to proceed.
Do you see * or # button below the 9 key on cable remote, it could be labeled as Format, try that button to change picture size.
OK, you can confirm your TV by connecting another video source such as DVD, Bluray or gaming console to see if it displays normal size picture?
If it is then it will confirm that directv box has got internal issue and should be replaced by company to resolve the problem.
You would need to confirm your TV as I suggested in previous reply by hooking any other video device such as DVD player etc, do you get normal size picture now?
