The is a widely utilized integrated power supply unit (PSU) and LED driver board found in many LCD/LED televisions produced by Vestel, a major Turkish manufacturer that OEMs sets for brands like Toshiba, Telefunken, Hitachi, JVC, and Bush.
Vestel does not publicly release schematics, but they circulate among service centers and online repair communities. Reliable sources:
If the TV is dead, experiencing power cycling, or has no picture but has sound, the 17IPS12 is often the culprit. Symptom 1: No Standby Light (Dead TV)
A concise summary of the board's layout, including major voltage rails (+12V, +24V) and key diodes (like the STPS20H100CFP ), can be found on Scribd's Vestel 17IPS12 Overview .
Employs an H-bridge switching circuit to drive the display's backlight. A common failure in this section results in "sound but no picture". Troubleshooting Guide If you are repairing a board, common diagnostic steps include:
Look for burned or high-value resistors around the MOSFET. 5.
