Hi Michell Cuellar ,
The best way to tell if it is OK or not is with the power disconnected and then to connect an Ohmmeter across the fuse and measure its' resistance. It should measure 0.00 (zero) Ohms i.e. short circuit
It is a slow blow fuse that is designed not to blow when the power is first connected to the TV and that is just the type of case that it is in.
Your particular fuse shows T5AH 250V The T indicates "Timed" (aka slow blow) which means that it can withstand the inrush current when the power is first connected.
The inrush current which only lasts for a few milliseconds if that, is higher than the fuse rating but because the fuse is a slow blow it won't rupture immediately but holds long enough until the current has subsided to what the normal value is. A standard fuse would blow immediately that the power was connected. If you need a replacement fuse check the end caps of the new fuse as its’ rating is stamped there, including the T
High inrush current can occur because capacitors in the circuit may have little or no charge left in them and offer less reactance to the voltage applied therefore initially higher current flows. Once the capacitors start charging the current decreases. As I said this all occurs in a few milliseconds
