I have a DCL9A monitor. I'm also having problems with my volume. One minute it worked the next it quit. I tried turning the volume up that didn't work. I'm not computer wizard, but if I had to guess the problem is inside the monitor. I sure could use some help figuring it out.

Re: Volume quit very fustrating.
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!

make sure your sound is turned up, be sure if you have external speakers be sure they are plugged in and they are on and turn the volume half way up. Next open the speaker on the lower right side on the task bar double click on it and raise the volume up next be sure the speaker does not have a red x in it, if thats OK then update your windows media player and try again, also be sure that windows medial player does not have the volume turned down and be sure the speaker is not x'ed out in media player. hope this helps. Thanks for using fix-ya.
Monitor volume is affected by TWO volume controls (or even three...) 1: Volume on the monitor can be set to 80% 2: Main Volume on the COMPUTER can be set to your liking. 3: Wave volume on the computer mixer settings should be set for 80% (See Sound on your control panel or right click your volume control near the clock)
If all these are right and the volume is still low, check that the audio is not set for surround 5 or 7 channel and the monitor audio connector is plugged into the REAR green connection on the computer.
Still problems, the audio driver in the monitor is shot.
I presume that it worked at one time and now it doesn't. I don't know what operating system you have, but generally you shoud see a little speaker icon on the lower right hand corner of your monitor, next to the time. Doble click on that and it should bring up the volume control. Besure that the "mute" is not on and that the volume is turned up to at least the middle area. If this doesn't fix your problem then there are some deeper fixes that can be done
Make sure there is a cable running from your computer to the monitor's integrated speakers. It should go from a green 3.5mm output jack at the back of the computer to one the same size in the back of the monitor. If the cable is there and still no sound, double check the connection, make sure they are plugged in securely at both ends. Be sure that headphones are not plugged into the computer at the same time or audio will only come out through the headphones.
Make sure the audio is not muted. There is a mute in possibly 3 places. One spot is the application audio: if you're trying to play from Windows Media Player, make sure the audio is not muted near the slider and that the volume is loud enough to hear. Second place is the system volume. In the Control Panel, Audio (Start menu, Settings, Control Panel, Audio component) you can check the volume and mute of the system volume. Third location is the monitor speakers. There may be a way in the monitor's menu to adjust the volume for the speakers. Make sure it is high enough to be audible.
If all of those are unmuted and high, you might try replacing the audio cable. Also reboot the computer with the audio cable plugged in where it should be. (Sometimes high-def digital audio can be quirky). Next try plugging in a pair of headphones into the front of the computer and see if you're getting any sound through there.
Those steps should help you diagnose the problem. If not, just post back with what you found out through these steps.
Lower down resoluction and color quality to minimum on your pc, using 'display properties' in Windows. Connect the monitor back to pc with minimal settings. If it works is done.
If it still does not work there is a major problem with the monitor. In this case It should be opened and tested inside following schematics. In this case you may need to take the monitor to a service in your area.
