C593 Microtek I am unable to get sound on the monitor does it have speakers????

check speaker cable, may be the speaker cable not connected properly

It "does not have any" unless you have installed some and they dont work..in that case i cant tell you.

AC adapter, the bad part is you cannot tell if it is in working condition until you have power supply to try it out first, for 15" used monitor, I will not spend $20 on it.

no data is getting to the monitor , check cable

No sync could mean the computer is generating signal at a frequency that cannot be supported by the monitor. As soon as Windows starts to boot, press F8 to display the boot menu. One of the choices will be VGA mode. Select it, boot into Windows, then set your resolution/refresh low. Reboot into normal Windows mode. If you now get display, then set the resolution/frequency to your liking (as long as supported by your monitor).

Monitor does not need sound driver, just think of it as nothing more than powered PC speakers mounted inside monitor case. You need correct sound card driver in the PC to get sound.
Testing monitor speakers: use an MP3 player to feed to monitor audio line input (Green jack) using audio cable with mini stereo male phone jack at both ends (try Radio Shack) , set the volume on the monitor half way. If you get the sound OK, then the problem is in the PC setup.

You may have shorted out the AC plug. You'll need to test it for continuity by using a voltmeter.

If it is shorted out, then you'll need to have the plug replaced.

Your Minotor not support windows 7 frequincy or resulation.please open your computer safe mode, and set monitor frequincy only 60Hz. Resulation less area .Then solve your problem.

Speakers don't work on monitor

There are no speakers on that monitor. Those are 'dummy' holes.

There are no AUDIO IN jacks on the back either.
