Not likely, the ptc circuit is before any 1.6A or lower fuse size. They have a 4 amp slow blow or similar sized fuse between it and the ac line. The typical Horizontal output/SMPS combination uses around 1 amp of current and would be protected by that size fuse.
The OP needs to troubleshoot the circuit and find the excessive current draw. Since the repair attempt was to initially replace the fuse, more likely new damage was caused. For the same reason the OP probably needs to send the tv to a qualified technician for a proper repair diagnosis.
