XBR-55HX927 SAFETY-RELATED COMPONENT WARNING There are critical components used in LCD color TVs that are important for safety. These components are identified with shading and mark on the schematic diagrams and the electrical parts list. It is essential that these critical parts be replaced only with the part number specified in the electrical parts list to prevent electric shock, fire, or other hazard. NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and labor guarantee. USE CAUTION WHEN HANDLING THE LCD PANEL When repairing the LCD panel, be sure you are grounded by using a wrist band. When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear cover. • Avoid contact with water as it may a short circuit within the module. To avoid damaging the LCD panel: Ú do not press on the panel or frame edge to avoid the risk of electric shock.

XBR-55HX927 The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation e.g. H1 etc [ see example ]. The servicing of these boards requires special precautions to be taken as outlined below.
XBR-55HX927 SAFETY CHECK-OUT The AC leakage from any exposed metal part to earth ground and After correcting the original service problem, perform the following from all exposed metal parts to any exposed metal part having a safety checks before releasing the set to the customer: return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splashes and 1. A commercial leakage tester, such as the Simpson 229 or RCA bridges. WT-540A. Follow the manufacturers’ instructions to use these instructions. 2. Check the interboard wiring to ensure that no wires are pinched or touching high-wattage resistors. 2. A battery-operated AC milliampmeter. The Data Precision 245 digital multimeter is suitable for this job. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators. 3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low voltage scale. 4. Look for unauthorized replacement parts, particularly transistors, The Simpson’s 250 and Sanwa SH-63TRD are examples of that were installed during a previous repair. Point them out to the passive VOMs that are suitable. Nearly all battery-operated digital customer and recommend their replacement. multimeters that have a 2 VAC range are suitable (see Figure A). 5. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their How to Find a Good Earth Ground replacement.
