Picture Breaks into Pixels
A typical example of a reception problem includes the
break up of pictures
(pixilation) or the
picture freezing
,
sometimes there are
clicking or squeaking
sounds or the
sound drops out
or there is
NO reception
at all.
Your picture may break into pixels due to the digital video signal dropping. The signal dropping may occur because of
either problems with weak signals (see TV Aerials) or if you are connected by cable a weak cable signal. If the problem
is weak signals, use an amplifier to strengthen the signal. A cable technician can help you install an inline amplifier or a
pre-amplifier. This will boost your signal strength and fix the pixel problem.
If you are receiving your TV signal by satellite, check your dish has not moved following high winds, or that the signal is
blocked by trees. Trees can be a problem as the TV signal can change depending if a tree between the satellite dish and
satellite is in bare or in full leaf.
Missing channels
It may be that you find that there are
channels missing
, or you're receiving channels from the wrong region.
Sometimes the i
nteractive services (red button) doesn't work
. This is usually caused by weak signal, see TV Aerials
TV Aerials
Digital terrestrial television (Freeview) comes to your TV via an aerial, The old aerial that was good for analogue TV may
not work well for digital so may need upgrading. If you are getting some but not all of the digital channels on DTV
(Freeview) for example you get BBC1, BBC2, Channel 4 ,but not ITV or Channel 5, this is usually because your aerial is a
narrow band type, and needs to be changed to a wide band type.
Faulty Leads and Cables
Check your TV. Are the leads at the back - to the mains, the aerial, the set-top box, the video or DVD player or recorder
properly connected? SCART leads are known to work loose over time and can result in both audio and video (picture)
problems. Either left or right or both audio is missing and the colours are poor or muddy looking. Push the SCART
plugs firmly in, this should fix the problem.
HDMI plugs need to be pushed in firmly; it's only the last millimetre that the contacts make. Typically the black plastic
part of the HDMI plug should be very close or touching the body of the TV or component.
When plugging in any HDMI cables you may experience problems if the HDMI cables are plugged in when the TV or the
other component is switched on. Always switch off both the TV and the component you are plugging in. If you have
checked the plugs and sockets, switch off the TV and whatever you have plugged in to the TV and then switch them on
again.
I have connected my PC to the TV. There is no sound.
If you connect your PC or Laptop to the TV using a VGA (15 pin Sub D) cable there is no audio, you need to connect a
separate audio cable to the TV from the PC or laptop.
Unnatural Colours and Flesh Tones
Unnatural flesh tones and other colours could present another problem even in a new HDTV. This is due to the TV
picture settings, which are optimized for a showroom environment. Fix this by changing the picture mode to natural in
the picture menu. For more precision, try manually setting the colour, contrast and brightness options in the picture
menu.
White Outlines
White outlines around objects and people generally appear either if the TV sharpness is set to very high, or if your
television set uses some edge-enhancement processing technology. Go to the picture menu and adjust the sharpness
till the white outline disappears. If edge-enhancement is enabled, try to disable it using the service menu.
Choppy Video
At times the video might become choppy. When this happens, check whether the signal is strong enough. If the signal
is strong the problem is with the cable operator. If the signal strength is weak, try boosting the signal strength with the
help of an amplifier.
The picture does not fill the screen
When connecting PC's or laptops to the TV, the picture may not fill the screen. Check the display settings on your PC or
laptop (Windows > Start > Control Panel > Appearance and Personalization > Display settings) and select the best
resolution. On your TV select:- TV Menu > Picture > Settings and then try AUTO, ZOOM1 or ZOOM2 for the best display.
USB Connection
The USB connection will work with *.jpg (photo) and *.mp3 (music) files. Please note the TV does not recognize Apple
iPhone, or iPod's connected to the USB connector on the TV. The TV may play other files, but due to the multiple
different file formats, there is no guarantee that these other file formats will work.
