Does a Raspberry Pi TVHAT die?

boodles

Hello all. I've been using a Raspberry Pi 3+ with a TVHat for several years with intermittent hiccups. Has to be said, it's a temperamental setup and I've had to reseat the TVHat a number of times. On occasion, wipe and reload the OS (debian) and reconfigure. I've always managed to revive it... but this time is proving more stubborn.

The TV signal is good, tested on a neighbouring TV, and I've ensured the antenna is firmly pushed it (it's always been lose; a design fault?) but no joy.

What other test can I perform? I'm wondering if the TVHat card itself has finally died.

I think it might well be the card. I don't think it's seating down correctly as the green light is now longer coming on. It comes on if I really press hard down on the card but goes out as soon as I let go. This was after I took it all apart to examine the antenna connection for possible problems.
