Question:

How to troubleshoot video quality issues such as pixelization, tiling, or lines on the screen?

Answer:

If you are experiencing problems like pixelization, tiling, or lines through the screen, try this: 

• Change to another channel. If the problem goes away, the problem was not caused by the TV.
• Test another box or DVD player on the same input that you are having the problem on. You can also try connecting the HD box (with the same connections) to another TV. If the problem follows the box, your problem is with the HD box and not the TV.
