Hantarex Polo 25 blows main fuse instantly

I think what anyone will tell you now is to take it out and check for shorts.

leave it off for a little while though, those drive transistors on the neckboard always shock me, even after discharging the tube 74 times. lol

Polos are known for going spontaneous kablooie for no reason. if the HOT dies, that takes the flyback out too... it's weird.

if you need any in-depth help on this, wait for someone else, cause I don't work on em to this scope. I'm a capkit/cold solder kinda guy when it comes to monitors.
 
What causes this? It was working great, now blows the fuse the second I turn it on.



Is the HOT a BU508a?
Did it short again after replacing..
Did you use a insulator?
Disconnect the HOT or remove it,whats the B+
measure is it 138v's at C121 or tp6
check for low ohms around the retrace caps
or replace fly..Etc
If fuse still blows after removing transistor T114 then,problem may not be in the
horiz-circuit..Desolder the Vertical ic 103 it could be shorted..
