Master 39s Led Lcd Tv Repairing And Screen Bypassing Book Pdf 'link' (2025)

“Master’s Guide to LED/LCD TV Repair & Screen Bypassing Techniques”

This content is designed for intermediate to advanced technicians. It focuses on real-world diagnostics, component-level repairs, and the specific skill of bypassing faulty screen circuits to salvage a working TV.

Key Features of the Book:

• Component-Level Troubleshooting: How to test a diode or MOSFET while it is still on the board.
• Voltage Maps: Specific voltage readings for standby (3.3V), 12V, 24V, and 100V backlight rails.
• The Art of Bypassing: Techniques to trick the mainboard into turning on even if the screen is dead.

1. The Power Supply (SMPS)

This is the most common failure point.

• Symptoms: Dead TV, standby light blinking, clicking sounds.
• Common Faults: Blown fuses, bulged capacitors, or shorted MOSFETs.
• The Fix: Usually involves replacing capacitors or voltage regulators. This is the "bread and butter" of TV repair.
