When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a 

breakdown or an accident. 

Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclu-

sive-use soldering iron is recommendable. 

 

Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering 

capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land 

separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when 

completion of soldering is confirmed. 

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.   

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip 

after completion of soldering work. 

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.

 

 

 

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. 

The alphabet following the LF mark shows the kind of lead-free solder.

When mounting the monitor, be sure to use a wall-mount bracket that complies with the VESA-compatible

(200x200pitch)

 mounting 

method. SHARP recommends using M6 screws and tighten the screws. 

Note that screw hole depth of the monitor is 3/8 inch (10 mm). Loose mounting may cause the product to fall, resulting in serious personal 

injuries as well as damage to the product. The screw and hole should come together with over 5/16 inch 

(8 mm) length of thread. Use a bracket which has been approved for UL1678 standard, and which can endure at least 4 times or more the 

weight of the monitor.
