Vestel 17ips62 Schematic Link
For bench testing the 17IPS62 without the mainboard connected, the control pins must be enabled. Based on community analysis, the typical logic levels are:
The primary cause is typically one of two things:
: If the TV has sound but no picture, the issue often lies in the LED driver section of the 17IPS62, which may have failed or is not receiving the "backlight on" signal from the mainboard.

If you are diagnosing a 17IPS62 board, you will likely encounter one of the three scenarios below. Fault Symptom 1: Completely Dead TV (No Standby Light)
The Vestel 17IPS62 is a predictable, highly serviceable power supply board. Most failures boil down to shorted secondary Schottky diodes or degraded electrolytic capacitors. Armed with a reliable schematic diagram, a multimeter, and basic soldering skills, you can fix the majority of faults on this board for just a few dollars, saving a television from the landfill. For bench testing the 17IPS62 without the mainboard
The main connector connecting the Power Board to the Mainboard usually follows a standard Vestel pinout configuration. Always measure to confirm, but typically:

Measure the voltages at the output connector leading to the main logic board. Check for steady +12V and +5V . If these voltages are pulsing or low, check the optocoupler feedback loop or look for a short circuit on the mainboard side. Step 4: Backlight Voltage Check
If the voltage spikes up drastically (above 100V) and then drops back down to the main rail voltage (around 12V–24V), the 17IPS62 boost circuit is working perfectly. The board has entered protection mode because one or more LED strips inside the screen are burnt out open-circuit . You will need to disassemble the panel to replace the LED strips.
It was a five-cent part. A speck of carbon and ceramic.
If your TV utilizes this board and suddenly refuses to turn on, flashes a standby light, or has sound but no picture, you are dealing with a classic Vestel power supply failure. Understanding the and circuit topology is the key to executing a successful, low-cost repair. 1. Technical Specifications and Overview
