Check that the replacement fan is spinning ok.
If it is not spinning then test the power getting to it using a voltmeter. If it is not getting any power then you will need to troubleshoot the cause of that problem.
If the fan is getting power and spinning ok then the feedback wire may not be telling the TV that the fan is spinning - check for any loose breaks or connections on that wire.

Sorry for the delay in replying, I just received notification of your reply today.
There should be three wires on the fan - 12V, Ground and Feedback.
Check that third wire for any damage, and check where it connects to the board.
Hi, just checking in on your question. How did things turn out for you?
