Another tv question

Had some good advice a couple of months ago now need some more if anyone can help. I have a tv in main room downstairs and one in each bedroom upstairs today the ones upstairs don’t work and tv says no signal, in the roof there is a 4 way booster that all the ariels go from/to I think it had a red light on but not now could that be the problem? Can anyone help?

Did you have a thunderstorm last night?

We did this morning.

The four way splitter/booster is it a powered one? IE plugged into a socket somewere, if so worth checking the fuse.
The booster may have just died but lightning even without a direct strike can finish them off.

That’s why I asked! :wink: Many years a TV installer for Curry’s Comet etc…
