  • Page 7 When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear cover. Do not press on the panel or frame edge to avoid the risk of electric shock. Do not scratch or press on the panel with any sharp objects. Do not leave the module in high temperatures or in areas of high humidity for an extended period of time. Do not expose the LCD panel to direct sunlight. Avoid contact with water. It may cause a short circuit within the module. Disconnect the AC power when replacing the backlight or inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms.) 7. Always clean the LCD panel with a soft cloth material. 8. Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.

  • Page 8 CLEANING THE LCD PANEL CAUTION: When cleaning the TV, be sure to unplug the power cord to avoid any chance of electric shock. Clean the cabinet of the TV with a dry soft cloth. Wipe the LCD screen gently with a soft cloth. ; Stubborn stains may be removed with a cloth slightly moistened with a solution of mild soap and warm water. ; If using a chemically pretreated cloth, please follow the instruction provided on the package. ; Never use strong solvents such as a thinner, alcohol or benzine for cleaning. ; Periodic vacuuming of the ventilation openings is recommended to ensure proper ventilation. ; Do Not use paper towels, any type of abrasive pad, rags, rubber or vinyl materials to clean the screen. Using these materials could easily scratch the screen which may result in permanent damage. ; Do Not use any cleaning product containing alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, ammonia, benzine, thinner or insecticide. Using any of these harsh cleaners may result in permanent damage to the screen. ; Do Not spray water or detergent directly onto the TV screen . If liquid drips into the bottom of the screen it may cause a failure. KDL-40HX750/46HX750/46HX751/55HX750/55HX751...

Verify the AC outlet box retaining screw ground by connecting a 60W to 100W incandescent (not a neon or fluorescent lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential. (see Figure B) Trouble Light AC Outlet Box Figure B.
