Complaining is SO Mormonesque! DO something instead!
We've ALL got a couple of perfectly good TVs sitting around that will only pick up aliens attempting to contact Earth, because the Signals they picked up YEARS ago were analyzed to give THEM the idea how to contact us!
(Quit rambling - this is subject for another thread.)
Anyway, if ya got a small one that won't take up to much space, take the housing off and get to the High Voltage lead that goes to the side of the picture tube:
You'll find that this wire contains a LOT of what is known in the Prank World as: Unwanted Visitor Repulsion Energy, or UVRE.
Merely connect another wire from this junction in the old TV to your metal screen door.
Usually just one knock is sufficient to deliver a quantity of UVRE to any UV that a second knock is not necessary.
