Re: Samsung HPT5054 black screen
I don't know about the onboard LED, was not on our versions but there's a lot of posts for this series. Common fail is shorted upper buffer board and/or Ymain.
Try some searches using the model, panel version and board numbers and there should be plenty of info for you.
here's one to get you started.

Re: Samsung HPT5054 black screen
Some tests that were posted here from another post.
Check out the stickys too, Tom has plenty of references and videos including this version which is equivalent to 50C91/96 or Q91/96 models
