Vestel 17IPS62 Power Supply Schematic: A Comprehensive Repair Guide for Technicians
If the TV shows no standby light, the primary side is likely at fault.
If you’ve replaced the LED strips and want to prevent them from burning out again, use the schematic to find the ISET (Current Set) resistors. Increasing the resistance slightly will lower the backlight current and extend the life of the TV. Safety Warning
Most new schematics include a "Voltage Map." Use this to verify pins on the connector going to the mainboard (usually labeled CN4 or similar).
A boosted DC voltage (variable depending on screen size) to drive the LED strips. Key Components to Locate on the Schematic:
Measure the voltage at the LED connector. If it spikes and then drops, the LED strips inside the panel are likely open-circuit.
Controlled by a specific IC (like the MAP3202 or MP3394) which regulates the current to the backlights.
