Overview

The Sharp Runtka478wjzz is a replacement master backlight inverter board engineered for select Sharp 52-inch LCD televisions. In CCFL-backlit LCD TVs, the inverter board plays a critical role by converting the TV's DC power into the high-voltage AC signal required to illuminate the cold cathode fluorescent lamps behind the LCD panel. When this board fails, the most common symptom is a screen that appears completely dark or extremely dim even though audio and other TV functions continue to work normally. This replacement board carries the part number RUNTKA478WJZZ and is cross-referenced as Delta DAC-60T012 BF (2995317800).

This board is specifically compatible with Sharp models LC-52D85U, LC-52D65U, LC-C5255U, LC-52SB55U, LC-52SB57UN, and LC-52SB57U, and is designed for sets using the LK520D3LW50Z or LK520D3LW10Z display panels. Installation involves removing the TV's rear cover, disconnecting the failed board's ribbon cables and wire harnesses, and securing the replacement in its place — no soldering is required. It is important to verify both the part number and panel type before purchasing, as some Sharp 52-inch models use a paired master and slave inverter configuration, and this listing covers the master board only.

The inverter board converts low-voltage DC power into the high-voltage AC needed to drive the CCFL backlight lamps. When it fails, the screen may appear very dim, flicker, or show no picture at all despite the TV powering on.
Common symptoms of a failed inverter board include a very dark screen where you can faintly see the image with a flashlight, the backlight turning on briefly then shutting off, or uneven brightness and flickering across the display.
This is the master inverter board (RUNTKA478WJZZ / Delta DAC-60T012 BF). Some Sharp 52-inch models use both a master and slave board — confirm which board has failed before ordering.
