The check fan no.1 is on the screen,tv stays on 10 mins then shuts off, does fan need to be replaced?

In short yes it does. That means the fan is bad and needs to be replaced.

I cleaned dust off Samsungs 1 Fan it had n worked fine, But I was consider pulling blades off then it wouldnt pull in n collect dust but would get hotter quicker, But that tiny fan isnt cooling much off anyhow alone in center of tv…
