Picture Brea ks into Pi xels
A typical example of a reception problem in clude s the bre ak up of pi cture s (pixi latio n) or the picture freezing,
sometimes there are clicking or squeakin g sounds or the sound drops out or there is NO reception at all.
Your picture ma y break in to pixe ls due to t he digit al vide o signal dropping. The signal dropping may occur because of
either problems with weak signals (see TV Ae rial s) or if you a re connected by cable a weak cabl e signa l. If the p roblem
is weak signals, use an amplifier to strengthen the signal. A cable techni cian ca n help yo u insta ll an inl ine amp lifie r 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 follow ing hig h winds , or that t he sign al is
blocked by trees. Trees can be a problem as the TV sig nal can c hange depending if a tree b etwee n the sat ellit e dish an d
satellite is in bare or in full leaf.

Faulty Leads and Cables
Check your TV. Ar e the lea ds at the ba ck - to the m ains, t he aeri al, the s et-to p box, the v ideo or D VD play er or rec order
properly connected? SCART leads are known to work loose over time and can result in b oth aud io and vi deo (pi cture )
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 conta cts ma ke. Typica lly the b lack pl astic
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 p lugge d in when t he TV or th e
other component is switched on. Always switch off both the TV and the component yo u are plug ging in . If you ha ve

Unnatural Colours and Flesh Tones
Unnatural flesh tones and other colours could present another problem even in a n ew HDT V. This is due t o the TV
picture settings, which are optimized for a showroom envir onmen t. Fix thi s by chan ging th e pictu re mode t o natur al 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 do es not fi ll the sc reen
