Hi Aderajew, The new fuse also blew away means there is some shot circuit in the TV. No more fuse replacements please. There is nothing more you can do yourself.Take the set to some technician or a service center. Good luck.

May try to replace your power supply. Average cost runs $200 via Internet. Also may inspect test & replace deformed an or any bulging caps.

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.
I repair these power supplies. If you need furhter assistance, write to [email protected]

More likely to be either shorted out bridge rectifier or MOSFET in the primary circuits of the power supply. You need to Ohm out those parts.
