Basicly my screen just goes black and I can switch inputs but when I go back to the one where my digital box is plugged in my screen goes blank and black.
Can you confirm the digital box is on? Power light for example? Channel number?
Try pressing Guide or Settings, see if anything happens.
Yeah the digital box is on and I cant see the channel number anything and I've tried changing the channel but that wont work ethier same with pressing guide and settings
Which digital box? Which TV? What cables are being used? HD or SD?
Are you supposed to be able to see a channel number? I really think it is off though, the terminals allways output a black video stream when turned off.
Next I would be looking at the cables between the digital box and your TV.
If your TV is only up to 720p, but is trying to display a 1080i signal, that can happen.
