OP wanted to know whysurgepower strip ceased to work
I had direct experience of same and explained

When a power strip surge protector circuit fails, it leaves the load
(TV) still connected to AC mains and the surge. It only disconnects
protector circuits to protect them; not the appliance.

Why did that TV not work when connected directly to the wall? Why
did that TV work when connected via a cheap power strip? Protector
circuit does nothing to change that electricity. Mechanical reasons
(ie a three prong plug holds firmly while a two prong plug does not)
would explain those symptoms. Why are you harping on some irrelevant
electrical functions in a protector that does nothing for Jo's
problem? A TV connected to a cheap protector connects directly to AC
mains. Why would the TV not black out? More likely reason is a
mechanical problem - ie a failing wall receptacle.
