It was a Vestel 17IPS62.
The high-frequency AC on the transformer's secondary windings is rectified by high-speed Schottky diodes and smoothed by low-ESR electrolytic capacitors.
The board utilizes several specific integrated circuits (ICs) and discrete components that are common points of failure. Understanding these parts is key to a successful repair:
Disclaimer: Repairing power supplies involves high voltage and can be hazardous. Always disconnect from AC power before working on the board.
"Got you," Ilyas whispered.
: The 3.15 amp Wickman fuse acts as the first line of defense, but it rarely dies alone. The Rectifiers : Often, four RL207 diodes fail, creating a dead short. The "Chopper" MOSFET
The primary regulation is handled by a high-efficiency PWM controller IC located on the solder side of the board. Vestel frequently uses controllers like the or similar chips from Silergy or Leadtrend in this topology. The PWM IC drives a high-voltage MOSFET.
