<p>The <strong>Tiron TI-BK-LED-Matrix-CCFL-A173</strong> is a backlight conversion kit designed to replace the cold-cathode fluorescent lamp (CCFL) in a <strong>Matrix CCFL-A173</strong> display with an LED strip. The backlight provides the light needed to see the image on the LCD panel; the conversion changes this light source while retaining the existing display.</p>
<p>Its application is the <strong>maintenance and LED conversion</strong> of equipment incorporating the specified display, where the backlight is to be renewed without replacing the complete screen. The work is limited to the lighting system: the kit does not replace the panel or its display electronics. A dark screen alone therefore does not establish that this conversion will resolve the fault; the failed part of the equipment must first be identified.</p>
<p>The kit includes a <strong>rigid LED strip</strong> sized for the specified model, a pre-fitted aluminium support strip, the TI-INVL-S9601 converter and a connection cable with flying leads for soldering. The display itself is not included.</p>
<p>The converter supplies a single LED line using current regulation. Its Vin supply input accepts 10–24 V DC. This voltage applies to the converter input, not to a direct connection between the LED strip and the equipment’s power supply. The strip is supplied through connector CN2, with the positive output and return contacts connected as shown in the specifications.</p>
<p>The converter has a Vrmt input for remote on/off control and a separate Vbr input for <strong>analogue dimming</strong>. Vbr operates between 0 and 5 V, with 5 V corresponding to low brightness. Integration compatibility requires both the power supply and the equipment’s control signals to be checked; the 10–24 V supply range must not be applied to the dimming input.</p>
<p>Installation requires the flying leads to be connected by soldering and the power, control and output pin assignments to be observed. The converter is secured using double-sided adhesive tape. Before commissioning, the display reference, connection polarity and wiring correspondence with CN1 and CN2 must be checked. This is an integration kit with soldered connections, not a plug-in replacement requiring no work on the wiring.</p>
<p>As an installation precaution, work must be carried out with the equipment disconnected from its power supply and in accordance with its service instructions. The original CCFL inverter generates high voltage for the lamp; its output is not a compatible supply for the LED converter input. The CCFL tube is made of fragile glass and must be handled during removal so as to avoid breakage.</p>
<p>Documented compatibility is with the Matrix CCFL-A173. Matching screen size or resolution alone does not establish compatibility with other models. The diagonal and resolution in the specifications describe the compatible display, not an included display. Electrical and environmental limits explicitly assigned to the converter apply to the TI-INVL-S9601 and must not be interpreted as verified ratings for the complete kit.</p>
