Troubleshooting

If a problem occurs when you are using the TV, check the below

troubleshooting guide before calling for repair.

• Colour patches appear
at the corner of the
screen
• This may due to the magnetized device such as a
speaker near to your TV. Keep the device apart from
your TV. Alternately, you can also use the magnetic-
shielded speaker.
• Picture is tilted
• This may due to the earth magnetism. Refer to
“PICTURE TILT” on page 11 to correct the tilt.
• Image takes a short
period to be displayed
• Image required time to stabilize before display. This
is not a malfunction.
• TV may emit crackling
sound
• This is due to a sudden change in temperature
and it is not a malfunction. If the crackling sound
is too frequent, request your service technician for
inspection.
• Feel a slight electric
shock when touching
the TV screen
• This is due to the static electricity of the picture tube
and it will not harm the human body. This is not a
malfunction.

Detect function does
not work
• Please check that the AUTO SIGNAL DETECT
function is on or off.
• Turn the VCR or DVD player off, wait a while, then
turn it on again.
