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.

If the fuse blows again after replacing it, there's a shorted diode, bridge rectifier, capacitor or transistor in the power supply.

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.

Mastercraft 14-in. Chop Saw w/ Laser fuse problem


The fuse is more than likely, fine.
Instead, check the carbon brushes.
Once you have dis-assembled the unit, you will see the way the springs hold them in.
If you can't find the brushes, chances are, they've desintagrated into micron thick diamonds.
(Unfortunately, they're worthless diamonds lol)
Hope that helps the problem.

No power to tv when i plug it in. don't know if all the way dead way to check it?


I really need the make and model number to help you.

My understanding of what you have said is that there is no standby light and no clicking sounds when you power on your unit. If this is true regardless of what type of tv it is there is a fair chance that the main ac line fuse is blown.

To determine if the line fuse is blown, remove the rear cover panel and follow the ac power cord to where it connects to the circuit board. The ac fuse is a small glass cylinder, about a half inch long. Replace the fuse with the same amperage and ignore the voltage rating. If the new fuse blows as well, your looking at involved circuit work which should be referred to an experienced repair technician.

Sounds like the power surge may have blown the fuse in the TV. You can replace the fuse and see if that works. If not, more damage to the power supply unit may have occurred.
