A relative had a tv that would switch itself on, at any hour in
the night. I found the sensor that receives input from the remote
control, had the equivalent of silver migration to nearby traces.
Problem was solved by cleaning the nearby traces with a pencil
eraser.

In the description the fault I have "int goes to st/by" and says the
solution is to "check 2 x 270k in pri psu & STR54041"

Can anyone explain what this means? and how serious is it to fix?
