Troubleshooting Plasma and LCD TVs

  • PrintPrint
This document pertains to HP Plasma and LCD Televisions (TVs).
This document contains troubleshooting information to help resolve issues that occur after the television is installed and set up.
NOTE:For information on your MediaSmart TV, refer to HP SLC3760N MediaSmart LCD TV - Frequently Asked Questions .

No picture or no signal message

  1. If connecting a device using component cables, make sure all three color-coded cables are connected correctly.
  2. Is the input source powered on? Turn on the set-top box, DVD player, or other component you are trying to view, and, if needed, start play.
  3. Is the correct input signal source selected? Select the input source using the remote control: Press the device button on the remote control to control the TV, if applicable, and then press the button to select the input source. This button may be labeled Input or Source. If the button shows a single source, press the button again until you see the desired source; if the button shows a menu, press an Arrow button to highlight the source and then press OK or Select.
  4. Check if the OSD menu displays or try changing the input source.
    • Press the Menu button to open the OSD. If the menu displays, the panel is working.
    • Select a different input source using the remote control. Check that the video source is playing. If the no signal message is for a TV channel, press the CH button to display a different channel.
  5. Did any image display when you turned on the TV?
    • If yes, check the cables to the input source and also select the input source using the remote control.
    • If no, see the next section, No power .

No power

  1. If the power indicator on the TV is off, press Power on the TV to turn it on.
  2. Is the AC cord disconnected? Make sure both ends of the power cord are plugged in.
  3. 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.
  4. If using a power strip, check that the power strip is turned on. Do other electronic devices plugged into the power strip have power?

Picture quality problems (such as lines, fuzzy image, or wrong colors)

  1. Check the cables and connections:
    Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
    Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
  2. Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal.
    For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
    If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
    If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem.
    NOTE:Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Open OSD to adjust the picture:
    Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed.
    If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.

No sound

NOTE:If your TV is experiencing audio problems when using an HDMI connection, refer to HP TVs - Resolving Audio Problems .
  1. Is mute turned on? Press the Mute button, or the Vol+ button to turn off mute.
  2. Is the volume too low? Press the Vol+ button.
  3. If your TV has detachable speakers or is connected to an external sound system (home theater or stereo), are the speaker or audio cables connected to the TV?
  4. Check the OSD setting to be sure the TV speakers are on; refer to "Using the Onscreen Display" for your model TV. Some TV models mute the display speakers when Variable is selected for the option controlling the type of output to an external sound system.

Poor sound quality

  1. Press the CH button to display a different channel. Sound quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  2. Select a different input source using the remote control: Press the device button on the remote control to control the TV, if applicable, and then press the button to select the input source. This button may be labeled Input or Source. If the button shows a single source, press the button again until you see the desired source; if the button shows a menu, press an Arrow button to highlight the source and then press OK or Select. Check that the video source is playing. Sound quality problems on all sources may be caused by the television.
  3. If your TV has detachable speakers or is connected to an external sound system (home theater or stereo), are the speaker or audio cables connected to the TV?

Cannot view photographs from the memory card reader

Select models of HP TVs have a memory card reader. If the TV is not able to display content from a memory card, check the following:
  • The memory card type is supported by the memory card reader. Refer to the TV documentation.
  • The memory card is fully inserted. Remove the memory card and re-insert it.
  • Only one memory card is inserted in the memory card reader at a time. Inserting more than one memory card may confuse the reader or damage the memory card.
  • Does the TV have a special menu for viewing content from a memory card? Most TVs automatically read inserted memory cards, however, some require you manually turn on the function to read the memory card. Refer to the TV documentation.
  • The picture is too large. Some TVs display images up to 10,000 pixels wide. Larger images may not display properly. Refer to the TV documentation for size limits.
  • The picture file is in standard format. Save the pictures as JPG. Refer to the TV documentation for other file formats it can read.
  • The picture files are not corrupted. Insert the memory card into a memory card reader attached to a computer. Confirm the files are readable.
  • The memory card does not use compression software. Some memory cards may use compression software to fit more pictures. The TV cannot read compressed files. Refer to the camera and memory card documentation to determine if it uses compression.
  • The memory card is properly formatted. Check the memory card documentation for recommendations for methods formatting the card. If possible, format the card using a computer using Windows.
  • The metal contacts of the memory card are clean. Use a lint free cloth and small amounts of isopropyl to remove any dirt.
  • The memory card is not damaged. Test using another memory card or insert the memory card into another memory card reader.
  • The pins in the memory card reader slots are not damaged. Remove the memory card and shine a light into the empty slot. If pins are bent, turn off the TV, disconnect the power cord, and straighten the pins with the end of a mechanical pencil. If the pins cannot be straightened, contact customer service
  • If the TV stops responding, remove the card and restart the TV.

Resetting the TV

If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:
NOTE:Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
