A common problem TV you might experience is a lack of picture when you turn on your TV. Philips LCD TVs are no exception. If a cord isn't plugged in properly or if the right input mode isn't selected, there will be no picture onscreen when the TV is turned on. If your Philips LCD TV has no picture, there are several possible reasons why, most of which are not difficult to remedy.
Reposition your TV and audio/video device (like a Blu-ray player) so you can access both of the back connections panels. Firmly insert the HDMI cable in the port labelled "HDMI" on each device, and then turn them both on and press the "Source" button on the remote to select "HDMI" as your TV's input mode. If there is still no picture, replace the HDMI cable with an HDMI-certified cable.
Turn off your TV and other audio/video device and look at the cables connecting them together. Component cables are made up of three separate video connections (red, blue, and green); composite cables have one video connection (yellow), and S-video cables have one video connection (black). Firmly insert each coloured connection in the labelled port for the corresponding connection type and colour. Turn on your TV and audio/video device, and then switch your TV's input mode to the proper input, such as "S-video," for example. If there is still no picture, replace the cable with a new one.
Turn off your TV and cable box (if applicable). Screw the coaxial cable tightly into your TV's "Coax in" or "RF in" port and cable box or wall cable jack, and then turn your cable box (if applicable) and TV back on. If there is still no picture, press the "Menu" button on your TV remote and select "Auto program" to perform the channel finding operation.
