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 colour; 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.
Sport
Sport 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 colours 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.
User
User mode allows you to save your favourite video and audio settings.
Favourite channel mode in TV mode (default setting)
Favourite channel allows you to store your favourite TV channels and flick between them
at the touch of a button.

Channel scan ordering
1. If your country supports ‘LCN’ (logical channel numbers)*, via Digital Channel
broadcasting, these channels will always have the highest priority.
2. If your country does not support DTV LCN, scanned channel numbers will start from ch801
in order of frequency.
3. ATV channels will start from ch901, and follow the current ATV channel sorting rules.
If the highest DTV number is larger than 901, ATV channels will be sorted starting from
chX01 (X=10, 11…) depending on the LCN channel's digit count.
4. If there is any LCN conflict, either between ATV LCN and DTV LCN, the conflicting channel
will be stored in a channel location after ch800.
5. The TV will automatically detect new channels, and if a new channel is detected it will
place the LCN channel in its LCN position. If there's no LCN, or the channel position has
already been occupied, the channel will be located at the end of the non-LCN channel
list.
6. If there is no digital service after auto-scan, the analog channel may be located from
ch001. Referring to rule 3, the X in this case will be 0.
In some European countries, the TV broadcast will embed the LCN (logical channel
number) in the DTV signal to allocate a channel number.

Troubleshooting
Before you call the Acer service center, please check the following items:
English
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.
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.
