While I don't own THAT model I have replaced fans, cleaned the internals of electronic devices for what seems decades.
It seems normal to me!

I have an approximately 7 year old Samsung TV. Occasionally, the tv emits a loud crackling noise and the color on the screen becomes flushed. The only way to stop the noise is to either turn the TV off or slighly tap if on the left side. The noise sounds like a fan blade hitting something.
I'm going to replace the orignal bulb to see if that's the problem.
Anyone else experience this?
