Sony KDL-42W900B Backlight Problem? External Driver & MOSFET Mod 🛠️ #ledpanelrepair #sonyelectronics

In this video, I tackle a common backlight issue on the Sony 42W920 LED TV where the 12V supply drops and the backlights don't stay on. I’ll show you how to bypass the original driver and install a CA-255 universal backlight driver using a specific MOSFET modification.

Technical Highlights:

The Problem: Identifying the 12V voltage drop caused by the faulty original driver circuit.
The Solution: Installing the CA-255 Universal Backlight Driver.
MOSFET Mod: Replacing the original MOSFET with a 7N65 and removing the current sensing resistors to ensure a stable 12V-24V output.
Wiring: Step-by-step connection for the ADJ and BL-ON signals to get the display working perfectly again.
This is a reliable way to save these Sony panels when original replacement boards are unavailable!
