Weight on power transformer

I think my power transformer is going out or something wacky is happening:)

I had  a channel that was coming in and out like a bad connection, first thought it was a cable so inadvertently placed my hand on top of the power transformer and the channel came in clear as a bell. I had to push down but it worked every single time the channel went from crackling to clear!!

Does that mean that it's about to go out?

thanks for your info.
