Care of the Screen
Clean the screen with a slightly damp, soft cloth. Do not use abrasive solvents as they may
damage the TV screen coating layer
Colours of image on screen are abnormal
For TV :
Have you selected the correct TV system? Is your TV set or house aerial located too close to
the 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? Check if you have entered the correct frequency.
The picture quality may degrade when two peripherals are connected to the TV at the same
time. In such a case, disconnect one of the peripherals.
For Monitor :
• Check that Video (Signal) Cable from the Display has been securely and correctly connected
to the 15-pin Video Connector on the rear panel of the Computer.
• If you have used an adaptor to convert the 15-pin Video (Signal) Cable Connector from the
Display to fit the connector on the rear of the Computer, check the pin assignment of the
Display.
