Neuroplasticity is a term that means the brain changes and adapts as a result of experience and stimuli. Neurons can and do form new connections throughout life. When the brain is injured, undamaged axons can grow new nerve endings to reconnect neurons whose links were injured or severed. For example, when I was in neuro-rehab early in my recovery, I couldn't solve the flashcard problem 7x4=?. After rehab that included speech and occupational therapy, on a neuropsychological assessment a few months later I was evaluated as "very superior" in the math portion of the WAIS-IV test.

If the TV is uncomfortable now don't watch it. Your brain needs quiet rest. I'm not a neuropsychologist but in my experience the meditation may be useful, even if it doesn't seem the same as it was before the injury.

Are you presenting other symptoms such as memory loss, confusion, or inability to concentrate (such as your TV watching)? If so are you getting any professional treatments? If cognitive issues are bothersome a visit to a neurologist or physiatrist that works with TBI patients may be in order. They may recommend occupational or speech therapy.
