Ksz80 Ob S4lv02 Datasheet ^hot^ -

This board is the first suspect when a TV has sound but no picture, or shows vertical/horizontal lines and distorted colors. Technical Specifications and Connectivity

Because these boards are specific to certain TV models, they are typically found as salvaged or refurbished parts rather than new retail items. You can find listings for this specific board on eBay or Kupindo .

The most common issue is a blown surface-mount fuse (often labeled F1) near the LVDS connector. If this fuse is open, the board receives no power, resulting in a black screen despite a working backlight. ksz80 ob s4lv02 datasheet

The term "KSZ80" in this context is part of the board’s silk-screen assembly number, and it should not be confused with the Microchip KSZ8081 series of Ethernet PHYs, which share a similar prefix but serve entirely different functions. Overview of the KSZ80 OB S4LV0.2 T-CON Board

While a full "datasheet" in the semiconductor sense isn't public (as these are proprietary Sony/Samsung parts), repair technicians rely on the following technical characteristics: Specification Dual-channel LVDS (Low-Voltage Differential Signaling) Compatible Screen Size 40-inch LED/LCD Panels Major ICs The most common issue is a blown surface-mount

The T-CON board acts as the "brain" of the display panel. It receives video data from the television's main logic board (via LVDS cables) and translates it into the specific timing signals required by the Source and Gate drivers to activate the individual pixels on the LCD. Used extensively in the Sony KDL-40R470A and related 40-inch LED/LCD models.

Typically includes a Samsung or Sony proprietary timing controller chip 12V (VCC), VGH, VGL, and AVDD (Analog Supply) Status Indicators
