Signal loss from antenna: Bad TV tuner

Just wanted to share this for those of you who have antennas split to multiple TVs.

I have a large 4 bay antenna mounted in my attic. It runs to a 3 way splitter and out to three TVs. When installed I was pulling in 42 channels to each TV. Recently my porch tv stopped receiving CBS and about 20 other channels.

Everything I read on the internet pointed me towards the splitter or the coax or needing some sort of amplification. I was about to start swapping lines and positions on the splitter when I thought, “let me check the tv”.

I pulled my spare tv out of storage (which is the exact same model Samsung that is already on the porch). Hooked it up and did a channel scan and sure enough it was pulling in 42 channels.

I know CSB TLDR but I didn’t realize the tuners in the TV could go bad.

Also this is good news because I need these old dinosaur Samsung’s to die so I can buy a bigger smart tv for the porch.
