Scenario mode in TV (default setting)
Scenario mode has five preset viewing modes designed to give you the best picture quality when watching a particular kind of
programme. There are five pre-defined audio and video settings for optimal enjoyment of the following scenarios: Standard TV,
Movie, Sport, Concert, Game, User.
Mode Information
Standard Standard mode allows you to watch your favourite channels with sharp, brilliant imagery via adaptive brightness
and contrast adjustments, and listen to clear-sounding audio.
Movie
For comfortably enjoying movies at home, Movie mode displays dim scenes in clear detail; compensates
for color; and smoothly presents motion images. This is accomplished through optimal Gamma correction
plus saturation, brightness and contrast adjustments. Movie mode makes the most of high-definition movie
soundtracks.
Game
Game mode carefully details the exquisite graphics of modern video games, providing lifelike entertainment
while protecting your eyesight by adjusting brightness and contrast. What's more, Game mode provides a
heightened audio experience.
Sports
Sports mode is suited for outdoor sports programmes, with accurate background depth and clear gradation
between the bright, outdoor playing field and darker auditoriums. Sports mode also brilliantly enhances
colors and presents swiftly moving pictures without residual images. All of this is achieved via specific Gamma
corrections and saturation adjustments. Precise audio can be heard.
Concert
Concert mode places you in a virtual concert hall, opera house or other dim environment by means of adaptive
brightness and contrast adjustments. Concert mode accentuates symphonic harmonies and the tenor audio
range.
Default setting in different Empowering mode

Troubleshooting
Before you call the Acer service center, please check the following items:
Here is a list of possible situations that may arise during the use of your LCD TV. Easy answers and solutions are provided for each.
There is no picture or sound.
• Make sure the power cord is properly inserted in the power outlet.
• Make sure the input mode is correctly set by your selected input.
• Make sure the antenna at the rear of the TV is properly connected.
• Make sure the main power switch is turned on.
• Make sure the volume is not set to minimum or the sound is not set to mute.
• Make sure the headphones are not connected.
• Reception other than those of broadcasting stations can be considered.
Picture is not clear.
• Make sure the antenna cable is properly connected.
• Consider whether your TV signal is being properly received.
• Poor picture quality can occur due to a VHS camera, camcorder, or other peripheral being connected at the same time. Switch
off one of the other peripherals.
• The 'ghost' or double image may be caused by obstruction to the antenna due to high-rise buildings or hills. Using a highly
directional antenna may improve the picture quality.
• The horizontal dotted lines shown on the pictures may be caused by electrical interference, e.g., hair dryer, nearby neon
lights, etc. Turn off or remove these.
Picture is too dark, too light or tinted.
• Check the colour adjustment.
• Check the brightness setting.
• Check the sharpness function.
• The fluorescent lamp may have reached the end of its service life.
Remote control does not work.
• Check the batteries of the remote control.
• Make sure the remote sensor window is not under strong fluorescent lighting.
• Try to clean the remote control sensor lens on the TV with a soft cloth.
• Use the buttons (hotkeys) on the TV before the remote control works.
If the above suggestions do not solve your technical issue, please refer to the warranty card for service information.
