Note: If the TV is "dead" (no standby light), check Pin 8/9 for 5V. If missing, the standby circuit is faulty.
Note: Always verify your board’s revision (e.g., 17IPS62 Rev 1.0, Rev 1.1, Rev 2.0) before comparing schematics. Small component changes exist.
Standby 3.3V/5V, Main 12V (or 24V in some versions), and LED Backlight Driver. 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.
If you can hear the TV audio and change channels, but the screen remains pitch black, your power supply's secondary side is working, but the LED backlight circuit has failed. Note: If the TV is "dead" (no standby
Check the startup resistors connected to the VCC pin of the PWM controller IC. If these open up, the IC never turns on. Fault Symptom 2: Standby Light Flashes Continuously
: It often integrates protection circuits that latch off the device if a fault (like a short or overvoltage) is detected. Common Troubleshooting Steps Small component changes exist
Commonly utilizes the MP9494 or similar high-efficiency switching controllers.
