Electronic parts wear out over time. Look at this breakdown of parts that fail most often on this specific board: Vestel 17IPS62 Power Supply Schematic | PDF - Scribd vestel 17ips62 schematic
The 17IPS62 is a combined power supply and backlight LED driver board produced by Vestel, a Turkish electronics manufacturer that supplies components for many third-party brands. This power supply board can be identified by the silkscreen text "17IPS62" prominently printed on the board itself, often followed by a revision number (e.g., version 2, -R4), indicating slight variations in the component layout across manufacturing periods.
These signals can be simulated using a separate low-voltage supply via a 1.8kΩ current-limiting resistor to the respective pins. "Got you," Ilyas whispered
