Ksz80 Ob S4lv02 Datasheet [updated] ❲2024-2026❳

The main logic processing core is working, but power is completely cut off from the analog array or panel glass.

The primary power inlet. Check this directly on both sides of the surface-mount input fuse (usually labeled F1 or FP1 ). If 12V is present on one side but not the other, the fuse is blown due to an overcurrent condition.

Using a multimeter, technicians check for VGH (typically +20V to +30V) and VGL (typically -5V to -10V). If these are missing, the screen will likely remain blank or display a slowly fading image. Where to Source Parts

When looking for a "datasheet" for this specific board, technicians typically refer to the service manual of the television or the functional specs of its primary ICs. : LED/LCD Scaler Board (PCB). ksz80 ob s4lv02 datasheet

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.

Do not route high-speed digital traces or clocks directly underneath or across the analog differential lines.

: It includes built-in termination resistors for differential pairs, which reduces the need for external components and simplifies board layout. The main logic processing core is working, but
