Ремонт ЖК-матриц (LCD панелей) | Как найти обрыв внутри матрицы и убрать полосы?

In this lesson, we'll move on to professional LCD panel repair. You'll learn about line (side) drivers, which technicians call "ears," and why they're most often the cause of a no-image or stripes on the screen. I'll cover in detail the synchronization signals (STV, CPV, OE) and the vital supply voltages of TFT transistors: VGH (V-on) and VGL (V-off). We'll explore how these signals work based on the "running lights" principle and why traces break right inside the glass. Most importantly, I'll demonstrate a method for diagnosing breaks using test points. You'll learn how to restore the panel's functionality simply by duplicating a broken trace with a thin wire from the T-CON or driver strip. This video will save thousands of TVs from the landfill! In this lesson: What is a side driver ("ear") and where is it located? STV signal (frame pulse) and relay transmission. CPV and OE signals: line synchronization. Primary voltages: VGH (gate charge) and VGL (discharge). Typical fault: broken traces in the glass. Repair method: duplicate the wires on the strip. How to find test points for soldering.
