Daewoo TFT-LCD Monitor Model No: L710

The Samsung SyncMaster P2570hd is a monitor with speakers; it isn't the computer itself. I'll assume that you are dealing with a computer connected to the monitor and not a set-top box. Make sure that Mute is not enabled on the computer. There should be an icon on the lower right hand side of a Windows desktop. If the mute is enabled, it will have a red circle with a diagonal line through it. Left click on the icon to remove the mute (change the volume or click on the mute icon). Test the monitor's speakers by connecting it to another device with known good audio output.

Next how are you connecting the monitor to the computer (VGA, DVI or HDMI)? If you are using VGA or DVI (including DVI to HDMI), you need to connect an audio patch cable (3.5 mm) between the speaker (green port on the back of a sound card) or headphone jack of the computer and the audio input jack of the monitor. The audio input jack is between the DVI and VGA ports. You can test the output of the speaker jack on the computer with regular computer speakers. Plug in the power cord (or USB cable) for powered speakers. If the free-standing speakers work, check the volume setting on the monitor with the +/- buttons to the right of the menu button. Do not press menu first, though. If that doesn't solve the problem, continue using the separate speakers. (Unless the monitor is still under warranty, it usually isn't worth taking apart a monitor to replace the speakers. You may be able find replacement parts online.)

If you are using an HDMI cable, check the output audio setting to see if the HDMI audio is available. For Windows, click on Start > Control Panel > Hardware and Sound (Windows 7). Then click on Manage Audio Devices under Sound. In the Playback tab, check what available audio devices you have. Make the HDMI the default device by right-clicking on it and selecting Make this the default device. (Other versions of Windows will a slightly different route to this panel.) You may need to restart the computer to get the audio signal on the HDMI cable after setting this. Note: not all video cards/computers support HDMI audio. If you don't see HDMI listed in the Playback devices, connect an audio patch cable as with a VGA or DVI cable, described above. Use stand-alone speakers if the monitor's speakers are bad.

I hope this helps.

(I have had the speakers fail in monitors; <$30 separate speakers are an adequate replacement for those built into a flat panel monitor.)

I got the same issue as above. You just need to register the base again by the step below:

1. Press the button on your base (like a speaker icon) without release it until you hear beep sound.
2. Press 'OK' to enter the MENU on your handset
3. Go to REGISTER
4. Then go to REG BASE
5. Press '1'. The screen will now showing SEARCHING BASE1
6. Wait a while then it will back to normal.
7. Put back your handset to the base and now the screen should show HANDSET 1.

Your cordless phone shall be ready to be used as normal again.

there is a black headphone jack just above the green one... try that one. also, try to plug in the jack and then turn on the monitor...

I have the 2436V (no speakers), but I suspect the solution will be similar. My screen was a bit to the left of the monitor's physical display area, and I was able to solve it using the built in menu (If you take too long deciding what menu button to press next, the menu will time out. Just start over if that happens. You will get faster with practice).

1) Press the menu button on the monitor (the menu appears).
2) Press the up button on the monitor 4 times to highlight the icon that looks like a slightly angled screen with yellow cross-hairs in one corner (the toolbar for positioning the screen appears - all 5 icons on the positioning toolbar are blue).
3) Press the menu button on the monitor to "enter" the selected toolbar (one of the toolbar icons turns green to indicate the selected tool on the toolbar).
4) Select the tool you need using the up/down arrow buttons on the monitor (I needed the one that moves the screen horizontally, you need the one that moves the screen vertically).
5) Press the menu button on the monitor to activate the selected tool (the meter above the toolbar icon turns green to indicate the tool is active).
6) Use the up/down buttons on the monitor to position the screen.
7) Press the menu button to exit back out (or, just let the menu time out).

Note: the disk that came with the monitor doesn't seem to have drivers for Windows 7, but allowing Windows to search online while updating the driver found a compatible driver online.

Hi,

You can use the function button in your keyboard + Mute sound button in the top keyboard rows to mute and unmute the sounds.

(fn key + Mute symbol key)

I hope this is helpful to you.
Thanks

When this occurs with mine, I power down the PC through windows and the monitor using the lower right power button, let bot sit for 10 - 20 seconds, then power on the PC and switch on the monitor a second or two later and the icon disappears.

Before I did this I found it would eventually disappear.

Acer support claim the H243H is a touchscreen unit, that's what the icon is all about, buy you must have Vista to use it, not XP.

did you hook up the sound cable to the computer? and is the sound not muted in the on screen display?
check and advise

This monitor does not have built in speakers you will need to buy some... The AS 500 soundbar fits on to it but is now not available. See if you can find it second hand.. Or buy USB speakers that fit into the back of your PC as the mointor does not have any ports.

Miniboy,

Don't relied on the mini-speakers, of course sound awful! It's has only 2 watts built in speakers. Try not to set at a full volume. Have fun!

Hey Mate, being honest weve sold alot of TFT monitors and most are hard to hear with all the volumes turned up, only thing you can try are. turn volume up to max on the monitors menu, also double click on the little speaker icon on the bottom right hand corner of the screen and a volume menu appears turn up WAV, & the main one on the left. if you are not getting any sound at all check you have the audio cable from the monitor plugged into the green connection on the back of the pc. Afraid thats the only options to get it louder or buy a set of speakers to get the sound louder. All the best John
