From one day to another, we suddenly lost our TV signal.
Aerial on top of roof doesn't look any different (not damaged). Antenna cable to TV looks fine.
Now, we can pay $$$ for someone to fix it, but thought I would ask here first, if anyone has any tips for fixing it?

Is there an signal amplifier that's come unplugged?
Have you tried another device?

Diagnosis means ruling things out. If you have anything between the TV and the antenna that you are aware of, you need to eliminate them one by one. If there is a splitter or booster or anything like that, try if possible to bypass them and connect the TV directly to the antenna to see if it makes any difference. Make the sure the TV itself isn't faulty. Can you get anything on any channel? Can you see anything on the screen, static, white blank screen, anything that suggests an image?. Depending on your location, you might be able to receive a signal of some kind with a small indoor antenna or even just a piece of wire. If so, that would tell you that the problem is not the TV. Ideally, try to borrow another TV to check that. Nothing at the antenna end is likely to cause sudden complete failure unless you have an amplifier there, but our recent weather could have done something to knock it out, perhaps heavy rain filling the balun with water or the wind breaking the aerial connection. Start with the easiest things first and work your way up.

Happy days!
Signal booster required power. The power plug was slightly loose.

The other one that usually caused a panic call from S I L is accidentally switching tv to now non existent analogue channels.
