Troubleshooting
Problem
• No power.
• The TV cannot be operated.
• Remote control unit does not operate.
• Picture is cut off.
• Strange colour, light colour, or dark
colour, or colour misalignment.
• Power is suddenly turned off.
• No picture.

sound.
Cautions regarding use in high and low temperature environments
• When the TV is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed.
This is not a malfunction, and the TV will recover when the temperature returns to normal.
• Do not leave the TV in a hot or cold location. Also, do not leave the TV in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
Storage temperature: -20 °C to e60 °C.

Fixing the TV on a wall
• This TV should be fixed on a wall only with the wall fix bracket available from SHARP (Page 5). The use of other wall
fix brackets may result in an unstable installation and may cause serious injuries.

Customers should not attempt to do the work themselves. SHARP bears no responsibility for improper fixing or
fixing that results in accident or injury.

• To use this TV fixed on a wall, first remove the adhesive tape at the two locations on the rear of the TV, and then use the screws
supplied with the wall fix bracket to secure the bracket to the rear of the TV.
