I cannot hear audio when using an HDMI connection - Why?

Make sure that the audio works fine when you are using a different connection type, such as a composite connector.
If you can view the picture, but cannot hear sound after connecting a DVD player, set-box, or other device using an HDMI cable, the firmware for the TV may may need to be updated.
Before updating your TV, make sure that the set-top box or DVD player is truly capable of supporting HDMI. Even though the device may have an HDMI connector, the HDMI signal may need to be turned on from inside the DVD or set-top box setup menu. The HDMI audio setting for the device may also need to be set to PCM and 48Hz as well.
To find out if your TV needs to be updated, do the following steps:
  1. With the TV on, press the Settings button on the remote control.
  2. From the Menu screen that opens, select About .
  3. Note whether HDMI EDID Version or VGA EDID Version is blank.

There is no picture or sound when using an HDMI connection - Why?

If you cannot view the picture and hear sound after connecting a DVD player, set-box or other device with an HDMI cable, the HDMI connector may have been damaged.
Look at the connectors on both the TV and the source device to see if the connector is damaged.
1 - HDMI connector with Center post (has metal contacts in place).
2 - HDMI connector with damaged Center post (missing or damaged contacts).
If the connector is damaged, the TV should be serviced to replace the mainboard.

Why can I hear sounds when using one type of cable and cannot hear sound with others?

You can hear sound from the TV when using one type of connector, and then lose audio when using a different connection. For example, You can hear audio from the TV when using a composite connection, but then lose audio when you replace the composite cable with a component style.
Several things can cause this. Try the following troubleshooting items:
  1. Make sure the proper audio connectors on the cable are connected to the proper audio connectors on the TV and the source device. For example, a component connection requires that the audio signal is sent and received from the left and right audio connectors in the same connector collection.
  2. Make sure the source device (DVD player, set-top box) is set to output audio from that connection. Some devices may need to be set to HDMI or composite through an internal menu.
  3. Make sure that you are viewing the proper source for the connection you are using. For example, if you are connected to a DVD player using a composite connection in Composite 1, set the TV source to Composite 1 using your remote control.
If all of these items have been tried and you still cannot hear audio, try a different cable. If the problem still continues the TV may need to be serviced to replace the main board assembly (connector panel/audio board/tuner amplifier board).

Why can't I get 5.1 audio channels when using HDMI?

Your TV supports PCM (2 channel/stereo) audio input. Any DVD player connected to the HDMI port should automatically default to stereo PCM audio. Stereo PCM audio is passed through the Digital output. If the the DVD player is set to use 5.1 over HDMI, you will not hear any audio, and the TV will not carry the audio to the digital audio output.
To hear stereo audio, use the setup menu for the DVD player and change the following settings:
(Menu screen may vary from manufacturer to manufacturer)
  • Dolby: set to "PCM"
  • MPEG: set to "PCM"
  • DTS: set to "Off" or "PCM" - Bitstream should be off
  • Sampling Frequency: 48 kHz
Other settings should not affect the audio output. PCM may also be listed as LPCM on some models.
To achieve 5.1 audio you will need to connect the audio cables from the DVD player to a separate home stereo system and connect the HDMI cable from the DVD player to the HDMI 2 port on the TV.

How come volume is too low when connected to a PC?

The volume is probably being sent from the PC at low volume. Adjust the volume on the TV to a normal level using the connection from the set-top box, VCR or DVD player. After the volume is set to a normal listening level, change the source on the TV to the connection the PC is sending it too and then adjust the volume from the PC until it reaches the normal level that you are used too.

Why can I can hear internal noises from the TV?

There are some internal parts that make sounds while the TV is operating. There are cooling fans that spin and a part called a color wheel that spins. Internal noise may be slightly louder when the TV is first turned on, but should subside to an unobtrusive volume after the TV warms up.
A low humming noise during the operation of the TV is normal. If the noise becomes substantially louder over time, a fan or the color wheel may be out of balance and the TV should be serviced to replace the fan or color wheel.

The TV speakers produce a low humming noise, even when the volume is muted - Why?

A low humming noise occurs on some mdTVs. This subtle noise usually occurs within acceptable limtis. If the humming noise becomes too loud and interrupts listening while viewing multimedia, the TV may require service to repair the mainboard.

How come it takes 5 to 6 seconds when changing High-Definition TV channels?

Switching between HD to analog or from analog to HD TV stations can take about 5 -6 seconds before the TV locks on the station. If this is the case, upgrade your firmware:
  1. With the TV on, press the Settings button on the remote control.
  2. From the Menu screen that open, select About .
  3. Look at the last three digits of the PW Version.
    If the last three digits are D23, PW Version: xxxxxxxD23, the firmware needs to be updated. To upgrade firmware, refer to the HP support document HP Pavilion md5020n, md5820n, md5880n, and md6580n High-Definition Microdisplay TV - Upgrade the Firmware. The new firmware should decrease the time to about three seconds.

Why can't I program my remote control for this TV?

If you cannot use your programmable remote control with the HP mdTV, the TV may need upgraded firmware in order to accept the codes from the remote control. To find out if your TV needs upgraded firmware, use the following steps.
  1. With the TV on, press the Settings button on the remote control that came with the TV.
  2. From the Menu screen that open, select About .
  3. Look at the last three digits of the PW Version.
    If the last three digits are D23, PW Version: xxxxxxxD23, the firmware needs to be updated. To upgrade firmware, refer to the HP support document HP Pavilion md5020n, md5820n, md5880n, and md6580n High-Definition Microdisplay TV - Upgrade the Firmware.

How come the remote control does nothing?

If the TV does not respond when pressing buttons on the remote control, check the following items:
  1. Replace the batteries using the correct orientation.
  2. Remove any obstructions that may be blocking the IR sensor in front of the TV.
  3. Point the remote at the TV and press a button. Did a blue light come on?
    • If a blue light on the TV lights, the IR sensor and the remote are sending and receiving signals. make sure the proper device is being used on the remote control. Restart the TV and try again.
    • If a blue light on the TV does not light, the IR sensor and the remote are not sending and receiving signals. Make sure the batteries in the remote are good. If the problem persists, the remote needs replaced or the IR sensor on the TV needs replaced.

Parts of picture overlap other parts of picture - Why?

If parts of the displayed image are repeated across the screen, and this happens fairly consistently, the hardware may need servicing. Make sure that any vents in the TV are not obstructed and the TV is not next to any heat producing sources. If the image overlapping continues, the TV will probably need to be serviced to replace the light Engine.

My TV has noticeable image quality problems. What do I do?

If the image problem is caused by some sort of contaminate inside, the TV can be service to have the contaminate removed. If a contaminate is causing the image problem, the image is will show a darker, shadowy outline of the material behind any image that is displayed.
If the problem is White horizontal lines across the top of the screen, a firmware update may resolve the issue. To upgrade firmware, refer to the HP support document HP Pavilion md5020n, md5820n, md5880n, and md6580n High-Definition Microdisplay TV - Upgrade the Firmware.
If the sides of the sides of the image appear to bow in slightly, this is a normal pinchushion effect in all/most rear-projection TVs.
If the top and bottom sides of the image bow in or out horizontally or are tilted, the TV can be serviced to "straighten" the image by adjustment of the baseplate.
For all other major image quality problems, such as
  • vertical banding,
  • vertical lines,
  • severe ghosting that does not come from the video signal,
  • colors are off and cannot be adjusted through the menu,
  • or the image is fuzzy and out of focus,
try using a different connection type to see if the image problem occurs with other connectors. If the problem persists, the TV requires service on the light engine.

The aspect ratio I selected does not stay after I restart the TV - Why?

This is normal. The TV will always start with a "Normal" aspect ratio.

I cannot use 1080p from my PC to the TV - Why?

Make sure the video card for your computer has updated drivers. Also, make sure that it is truly capable of outputting in 1080p (not just 1080i). With many cards,youwill have to go into advanced settings to select 1080p, if it is available.
