The plastic cabinet makes a
"clicking" type of sound
The remote control does not work
• The 'click' sound can occur when the temperature of the television changes. This change causes the television
cabinet to expand or contract, which makes the sound. This is normal and the TV is OK.
• Confirm that TV still has power and is operational.
• Change the batteries in the remote control.
• Check if the batteries are correctly installed.
