Question about Televison & Video
Did you mean that the TV is connected to the digital box or to the DTH.
If the digital box is using the video/audio signals to connect to the AV of the TV and you are having a blank the fault can be the video/audio signal amplifiers or the A/D convertor.
Please give some more inputs to the problem.
If using an RF input , then the tuner can be defective.

From your description you are getting some kind of display but no picture. What you need to do is change the input source. This tells the tv where to look for a incoming signal. If it is expecting a cable signal it looks for the signal on a differant connector than the one the antenna will be connected to. You will also have to scan so the tv's senses what channels it is seeing. So set the source first if its not set to the tight one then do a scan and you should be up and running.
You haven't given make or model so generally these are found under the menu button and then setup. This is usually the first few pages of the user manual.
