This section describes commonly encountered
issues and accompanying solutions.

General TV issues

The TV does not switch on:
•
Disconnect the power cable from the
power outlet. Wait for one minute then
reconnect it.
•
Check that the power cable is securely
connected.
The remote control is not working properly:
•
Check that the remote control batteries
are correctly inserted according to the
+/- orientation.
•
Replace the remote control batteries if
they are flat or weak.
• Clean the remote control and TV sensor
lens.
The standby light on the TV blinks red:
•
Disconnect the power cable from the
power outlet. Wait until the TV cools
down before reconnecting the power
cable. If the blinking reoccurs, contact
Philips Consumer Care.
The TV menu is in the wrong language.
•
Change the TV menu to your preferred
language.
When turning the TV on/off/to standby, you
hear a creaking sound from the TV chassis:
•
No action is required. The creaking sound
is normal expansion and contraction of
the TV as it cools and warms up. This
does not impact performance.

Picture issues

The TV is on, but there is no picture:
•
Check that the antenna is properly
connected to the TV.
• Check that the correct device is selected
as the TV source.
There is sound but no picture:

connection:

connected to the TV.
•
Loud speakers, unearthed audio devices,
neon lights, high buildings and other large
objects can influence reception quality.
If possible, try to improve the reception
quality by changing the antenna direction
or moving devices away from the TV.
•
If reception on only one channel is poor,
fine tune this channel.

devices:
