Question about Sharp LC-42D43U 42 in. LCD HDTV

1 Answer

Poor Volume We have the same issue with our LC-42D43U. The volume is poor. I called the store that we purchased it with and they said top buy an Amp.The old TV had good volume, so it isn't a cable or receiver problem.

    I found this on another site, tried it and it WORKED. It took a few swiches, but it worked.

    I have a Sharp LC-46D43U LCD TV. I think this is a entry level for
    large lcd tv's. With the volume all the way up at 60, my wife and I
    could barley hear the tv. I was playing around in the menu and some how
    have the volume at almost twice the volume. What I did was:

    Go into the menu

    Go to option

    Go to output select

    and change from fixed to variable and back to fixed. You may have to do this a few times.

    Sometimes the volume goes loud after 1 try and sometimes it may take 10 or 20 tries.

    But if I change any settings, even the channel sometimes the sound goes back down to where it was.

    Has anyone done this, did it work for you. I don't know very much about electronics and I have now ideal why this happens.

    I wonder if this is just something with my tv.

NOKIA 3315 sound problem (poor sound quality). Please Help!


Poor sound and quality: If you hear buzzing sounds during conversations or either during sound alerts, bring it to the nearest repair shop for replacment of speakers. However, if you only mean that you had a hard time listening to a call because of low volume, then do the following:
1. during the conversation, press the UP button, then, you will see the volume bar to appear. Keep pressing it until you reach the desired volume. When your done, just stop pressing or tapping and it will automatically return to call menu.
Enjoy Nokia 3315.

Hello Cricket,

Sound/Speakers that are built into monitors, typically are pretty poor. I suggest purchasing some speaker from your local electronics store, or www.newegg.com. (New Egg has very good deals on computers and accessories, like speakers.) Here is a link to New Egg's speaker section. http://www.newegg.com/Store/SubCategory.aspx?SubCategory=60&name=Speakers

On the back of your computer, you will see little holes (3.5mm). They are usually color coded, Green is the typical speaker output jack/hole/port. When you buy your speakers, you will plug the cable with Green Head Plug (3.5mm) that is attached to your speakers, into this Green Jack. Turn them on, and you should have audio! Now, if the volume seems weak, you can double click the speaker at the bottom right of your Start Bar in windows. It looks like a little silver circle. This is your volume control There are multiple slide bars to adjust your audio.

Good Luck!

Low sound volume when making a call


be sure there's nothing covering the speaker when you're talking. i would try looking in the tones settings if you have that. but some phones just don't have really good audio, but if this is a recent problem, then i'd suggest taking it to the store and getting it looked at
