Answer 1

Answer:

We have to check the video mode if we see that the TV was showing black or blue screen or had snow.

Explanation:

• When this situation takes place we have to see first whether the set- top box is working or not.
• We also need to check whether the TV is in video mode or not , it the TV is in video mode it will be showing blue screen.
• Snow occurs when there are problems in the circuits, transformers , signal lines etc.
• When such problems take place we need to install a good quality cable, screened wall plates and need to remove splitters.
