TV, the other aerial to your recorder, the power cables, ..)
• Verify if you selected the correct source.
• Verify if the child lock has been switched off.
• Verify in the Manual installation menu if you have selected the correct
TV system.
• Verify if your TV or house aerial isn't located too close to loudspeakers,
non-earthed audio equipment or neon lights, etc.
• Mountains or high buildings can cause double pictures or ghost images.
• Sometimes you can improve the picture quality by changing the direction
of the aerial.
• Is the picture or teletext unrecognisable or do you experience bad
teletext reception? Verify if you have entered the correct frequency, or
fine tune the frequency for that specific channel or adjust the antenna
direction if the problem isn't solved by finetuning. See Installation menu,
Manual installation, p. 24.

The liquid crystal panel is built with very high precision technology giving
you the fine picture details. Occassionally a few non-active pixels may
appear on the screen as a fixed point of red, blue, green, or black. Note
that this does not affect the performance of the set.
