Look for a cold solder joint in the vertical drive
Check the inductors in the vertical drive for a cold solder joint where windings attach to pins, as well as any transistors in the vertical drive section.
Check the caps in the power supply providing the low voltage to the audio and video processing IC's

Also chance that you have a bad X sustain board

If possible, plug the speakers into a portable device such as a cell phone, portable cd player or a tv that is equipped with a headphone jack (if speakers have the jack). If not, if the speakers have the red and white, ref and black or black and white male end connectors, plug them into a tv or dvd\blue ray player. If you get sound they are good, and you need to adjust your sound options on your computer. Let me know if this helps\works. Also, not all speakers are compatible with all computers and must have the same sound level equivalence to the device they are being used with. i.e. Ohms etc.

This information comes from the online reference book: Using the Sound Menu

Use the remote to open the TV menu. Select the Sound menu, and the "speakers" decision. From the two choices, "TV Speakers" tells the tv to use its built-in speakers. "Audio System" tells the TV to use an external audio system, and disables the internal speakers. Select "Audio System," and check to see if it works. If it still hasn't recognized that there is an external audio system plugged in, you may need to clean the stereo mini jack (3mm audio jack) with a small wooden toothpick or similar small diameter non-conducting device.

How do i get sound when using my emerson tv/monitor for a computer monitor


If you done't have a separate audio input, you can't. Some TV's that can be used for monitors have a separate audio jack just for that purpose. If it doesn't, then you will have to get a separare set of speakers and use them or a headset direct to the computer.

To convert a LCD Monitor into a TV
Instructions
    • 1

      Compare internal and external TV tuners that are designed for use with computers. See if the tuner supports HD, DVI, component video, S-video, stereo, surround sound or other features you might like to use. Ensure that any internal devices will work with the expansion slots in your computer.

    • 2

      Purchase a regular TV tuner if your monitor has S-video, coaxial or RCA inputs. These can be seen at the back of the monitor. S-video should be clearly marked; coaxial is a large round port, and RCA inputs are typically smaller and brightly colored. If your monitor does not have these inputs, purchase a special TV tuner designed just for computer monitors. If you would like to use the tuner with your computer and monitor, choose an internal TV tuner. If you're using your computer monitor as a television on its own, select a stand-alone external tuner. Install the internal TV in your computer, if applicable.

    • 3

      Connect the TV tuner to the monitor with the proper cable. Select S-video as the connection option if both your tuner and monitor support it. Choose RCA component video as your next option. Use coaxial only if your monitor and tuner do not have the aforementioned connections. If your monitor has none of these connections, use a standard VGA cable to connect the tuner and monitor.

    • 4

      Connect the tuner's audio outputs to your monitor's speakers. If your monitor has no speakers directly attached, connect external speakers to the TV tuner. This can usually be achieved using regular audio or RCA cable.

    • 5

      Install an HD antenna high on a wall if you will be picking up free over-the-air television signals with your monitor. If you will be using satellite or cable TV with your monitor, simply plug the satellite or cable set top box into the tuner using RCA or coaxial cables. Then connect the tuner directly to the monitor.

    • 6

      Set your tuner to the channel you use to pick up television stations. If you receive free over-the-air television, this channel will be 3 or 4. If you have satellite or cable TV, this station is determined by your television service provider. Check the documentation that came with your system to determine which channel to set the tuner on. You will probably need to change channels using the satellite or cable box rather than the TV tuner.

How are you getting the sound to your sound system?
HDMI? ANALOG AUDIO LINE OUT RED and WHITE RCAs? TOSLINK optical?
How does it sound with its own built-in TV speakers?

Hi,

You can only use your TV for viewing internet from your computer by using the TV as a PC monitor. To do this you should connect your computer to your TV using a standard VGA cable - the same as you would use to connect your computer to any other external monitor. You should note that this cable doesn't carry a sound signal so you can't use the TV speakers for sound output.

However, you can connect an HDMI cable from your computer to your TV to play media files or DVDs. This cable does carry a sound signal so you will be able to use your TV speakers here. This cable cannot be used for turning your TV into a PC monitor.

And all of above shouldn't be confused with "Internet TV". This is something totally different and requires your TV to be connected directly to the internet.

Hope this helps.

I am trying to connect wireless speakers to my tv, but if I turn the speakers off to the tv, the wire;ess ones dont work.Any solutions? Thanks!


You should do the following if the TV Audio set up will let you:
1) Turn the speakers TV OFF.
2) Set the Audio line out to 'VARIABLE' instead of 'FIXED' level.
3) Use the RCA jacks Audio line out to feed your wireless speakers line level input jacks.
4) Set the wireless speaker volume to be about half way up and use your TV rempte to control the sound level feeding the wireless speakers.

Your computer sound "out" jack has to be connected to the sound "in" jack at the back of the monitor(next to the vga input). To do this you need about a 3 foot stereo jumper cable with male connectors on both ends.
