SOURCE: Hi I have a l32hdtv10a that
NEVER EVER replace a fuse and think that the fuse will blow all by itself. The fuses are there to protect the set from catching on fire.In case there is a short inside the set. Now in some cases an intermittent short can work after you replace the fuse but if its burnt black or brownish, there is a short inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifiers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted.
If you have experience in repairing electronics, you could take a help from a service manual to find the values of different components to make sure that they are not out of order.You could buy the service manual from :-

Hope i helped you.
