I have an older Mitsubishi VS 4543A that shuts off a few seconds after it turns on. I hear 3 distinct clicks or buzzes from right side of set (facing back of set) and then it shuts down.
Just prior to this the set would take 15 minutes to fully come on, and after the 15 minutes it looked fairly normal.
I plan to give the set to a family that can't aford a big screen and am hoping I can fix it.
