TV have 2 prong power plugs, but the orientation matters very much when interconnecting equipment.
If I plug my 2-prong CRT in reverse I have 230V potential difference between equipment grounds !! that’s enough to fry any electronics.
Check AC voltage with a multimeter between equipment grounds that run form different power sockets, and between each device ground (composite shielding) and power socket ground,, flip the reversed 2 prong plug to prevent accidents.
