If the fuse is burnt, the wire inside will be broken or/and the fuse is black, if you have tester measure it for conductivity with ohmmeter. Replace with the same ratings fuse. If the TV doesn't power up other parts could be burnt and need replacement

Samsung tv CS-29M16MG fuse always blown

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

With the Samsung PPM42S3QX Power Supply Board is the likely the cause. Testing and diagnosing - Remove the back of the TV and check the voltages on the power supply. The output voltages will be labeled on the board. Look for obvious need for replacement such as swollen caps, bad fuse, burnt components.

You have either a bad relay or a bad capacitor inside the TV that will need repair or replacement. Most likely it is in the power supply section of the TV.
