memperbaiki regulator tv polytron ‼️mosfet 7n65c baru diganti langsung konslet

Repairing a Polytron TV regulator ‼️Newly replaced 7N65C MOSFET immediately short-circuited This time, I want to share how to repair a Polytron TV whose FET is always broken, damaged, and short-circuited. Before installing the MOSFET, ensure the gate voltage is 4V. If the gate voltage is not 4V, do not install the MOSFET unless you want to lose money. #rselektro #tvpolytron #servicetv
