Symptom Remedy
I get a poor picture with video signal
input. Check the following: Improper control setting. Local interference. Cable
interconnections. Adjust picture control as needed. Try another location
for the TV. Be sure that all connections are secure.
There is no picture or a blue screen,
and I have an external device
controlling the TV. ■ Press the Source button on the remote control and confirm the source
is selected.
■ Verify that the external device or PC power is turned on.
■ Check to see whether the source component is connected.
■ Check the power management function. Is it in standby mode?
■ Connect the source to the TV. Operate the external device or PC
(move the mouse, or press a key).
The picture, with a component input
source connected, is too red, blue, or
green, or has black that is too black
or washed out. ■ Check to make sure each cable is plugged into the correct color-
coded connector on the TV conncectors and input source connectors.
■ Make sure the cables are plugged in all the way.
■ See “Adjusting the AV picture image” on page 29.
