I do not see an image at power-on.
Are the connections to the input signal source component correct?
Double-check that the cables are properly inserted in the color-coded

Is the input source powered on? Turn on the set-top box, DVD player,
or other component you are trying to view.

Press the Menu button on the remote control or side of TV:
If the OSD appears, check the cables to the input source and
press the source button on the remote control or side of TV to

If the OSD does not display, see the next symptom, “There is no

Did the HP logo display when you turned on the TV? (TV must be in
Standby Mode Low power to see the logo; refer to “Selecting the
Standby Mode (Power Control)” on page 40.)
If yes, check the cables to the input source and press the source
button on the remote control or side of TV to choose the input
source.

There is no power.
Press the Power button on the remote control unit.
If the indicator on the TV is off, press the Power button on the TV.
Is the AC cord disconnected? Make sure both ends of the power cord
are plugged in.
Is there power coming from the outlet? Plug in a functional lamp or
other electrical device into the same outlet as the TV to make sure
there is power coming from the outlet.
If using a power strip, make sure it is turned on.
