hantarex polostar 28 inch [blown hot]

[ironblock]

recently bought a system 246 with soulcalibur 2 arcade. in a naomi universal cabinet.
bought the whole thing for 200 euro. the owner said it was broken. after i got it playing blind i bought it.
i can hear the HOT clicking. i have orderd a couple. what can cause a hot to blow ?
and can i just use a hantarex polo cap kit?

im gonna remove my flyback today to test it out of circuit.

this is my first time repairing a monitor.

thanks in advance.
