Issues No sound or picture I have connected an external source to my TV and I get no picture and/or sound. When I turn on my TV, there is a delay for a few seconds before the picture appears. Is this normal? The picture is normal but there is no sound Sound but no picture or black and white picture The sound and/or picture is distorted or appears wavy The sound and picture is blurry or cuts out A horizontal or vertical stripe appears on the picture and/or the picture is shaking The plastic cabinet makes a "clicking" type of sound The remote control does not work Possible solutions • Check if the power cord is plugged into a powered AC outlet. • Press the Power button on the remote control to activate the unit from 'Standby' mode. • Check to see if the LED light is on or not. If it is, then the TV is receiving power. • Check for the correct output connection on the external source and for the correct input connection on the TV. • Make sure you have made the correct selection for the input mode for the incoming signal. • Yes, this is normal. The TV is initializing and searching for previous setting information. • Check the volume settings. • Check if 'Mute' mode is set to On. • If the picture is black and white, unplug the TV from the AC outlet and replug it after 60 seconds. • Check that the Color is set to 50 or higher. • Try different TV channels. • An electric appliance may be affecting the TV. Turn off any appliances that are nearby and move it farther away from the TV. • Insert the power plug of the TV set into another power outlet. • If using an external antenna, check the direction, position and connection of the antenna. • Adjust the direction of your antenna or reset or fine tune the channel. • Check if there is an appliance or electric tool nearby that is causing interference. • 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. 15
