Condition
explanation / Solution
pC Input
Certain programs on DVD or 
other digital sources display a 
loss of detail, especially during 
fast-motion or dark scenes  This is due to the digital compression of the source content used by cer\
tain digital broadcasts and 
DVDs which may cause your TV’s screen to display less detail than usu\
al, or cause artifacts (small 
blocks or dots, pixilation) to appear on your screen. These signal comp\
ressions are more visible and are 
dependent on the clarity and resolution of the television. 
Remote control does not operate Check the polarity of the batteries or replace the batteries. 
Point the remote control at the remote control sensor located at the front of the TV. 
Fluorescent lamps can interfere with your remote control operation; try turning off the fluorescent lamps. 
Keep the remote control sensor area clear from obstacles.
