Hi. I'm Steve. I'm sorry to hear about your TV. I will try my best to give you a precise and accurate answer.
Has it always been this way or is the TV new to you?
Are you using a cable box? Make and model please?
Right. Have you always had this problem or did it 'just happen'?
I'm married and I love football :)
Ok. I'll give you a brief overview.
The satellite box and the TV both have screen size controls that govern the appearance of the image on the screen. Ideally, you want to set it correctly at the satellite box and then adjust it as required at the TV.
Now...if you can tell me the model of the box, I may be able to help you further.
For now though, grab the Sony remote and play with the screen size settings. If none of them are quite right, the sat box needs adjustment.
Ok, on the dish remote should be a 'Format' button. Press that a few times. Between that and the Sony remote, you should be able to get the picture right.
If not, then we need to check the setup on the box.
Just ask if you need more help on this issue. I will be here.
