Problem	Possible Solution
No sound	1	Ensure mute is not turned on. Pressing the Mute button on
		the remote control turns the mute function on and off.
	2	If only certain TV channels do not have sound, then you need to
		correct the Input Select menu in the TV Menu (see "Input
		Select" on page 26).
	3	Verify that the audio cables are firmly connected to both the
		audio input connectors on your TV and audio output
		connectors on your devices. Ensure that the cable colors match
		the connectors colors.
	4	Also, ensure that the audio cables are connected to the same
		row as the video cables. See "About Your TV" on page 5 for the
		location of the connectors.
	5	Reconnect the device using the same type of connector. For
		example, if you are using the composite connector on the
		bottom, try connecting the device to the composite connector
		on the left of the TV. See "About Your TV" on page 5 for the
		location of the connectors.
		After you connect the device, change the input source in the TV
		Menu. See "Input Select" on page 26 for more information.
	6	Connect the device using a different connector. For example,
		if you are experiencing the problem using a composite
		connector, try using the component connector.
		NOTE: To connect to a different connector, you need the
		appropriate cables for that connector. See your device
		documentation for a list of supported connections.
		After you connect the device, change the input source in the TV
		Menu. See "Input Select" on page 26 for more information.
	7	Test the device on a different TV.
	8	If you are using PIP/POP/PBP, ensure the proper Audio Source is
		selected. Press Menu button on your remote control, and select
		PIP/POP/PBP.
Double image or no image with DVD	Turn off the progressive scan on the DVD player. Your Dell™ TV
	offers built-in deinterlacer that is equal to or better quality than
	the deinterlacer on your DVD player. For more information
