TV ni problemnya langsung takde power. Lampu standby pun takde.
Terus check kat power supply dulu.
Langsung takde voltage pada secondary.
Primary harus ada masalah.
Cek ada short. Main fuse 5A pun putus.
Didapati punca masalahnya adalah
- N-Channel MOSFET 600V, 9A, 385mΩ.
- Power factor correction (PFC) controller
**PFC ic provides many protection functions, such as over-voltage protection, open- feedback protection, over-current protection, and under-voltage lockout protection.
