Re: how to repair
MY SUGGESTION IS TO BUY A REPLACEMENT MONITOR AN LCD BECAUSE IT USES LESS energy about 50% less and at a low voltage.
YOU PROBABLY CAN FIND ANOTHER RELAY AND CAPACITOR ONLINE OR AT A TV REPAIR SHOP electronics supply warehouse BUT IF THESE COMPONENTS WENT BAD
OTHER COPONENTS MAY BE BAD ALSO AS A RESULT OF THESE HAVING FAILED SOMTIMES RESISTORS,DIODES AND TRASISITORS LOOK GOOD VISUALLY BUT ARE NOT.
Save your self sometime and money by getting a new lcd monitor
even if you repair your monitor its still old if you replace this mointor with a new one you elimiate all risk because a new monitor will have all new parts and a warranty and save money on your electric bill because it takes less power to operate.

There is a short within the HT section and this can be possible with the failure of the flyback transformer or the driver transisitor. So if you are equipped please open the back panel and check for shorting on the driver, also when powered this can heat up which confirms that the flyback is shorted. replace with the same type.
First right click my computer then click properties then hardware then device manager and expand the sound video and game controller and see if the driver is marked with yellow question mark or marked with red X then you will have to reload the drivers and if you dont see any audio drivers then switch of the computer press del and enter bios and enable the audio device then click the volume control in theoolbar and check wether mute is clicked if clicked remove them and adjust volume slider to high
It sounds like you have a monitor with a common problem. After a few years some LCD monitors
will blow a power supply. The problem is caused by parts called
capacitors overheating in the confined space of the monitor. If you are
good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work
fine. The capacitors do need to be installed with the correct + and -
connections, note the stripe on the old one and insert the new one the
same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
I hope this helps, if so please rate my solution.

Please try to check the sound device status if its working properly thru right click My Computer icon > Properties > Hardware tab > Device Manager > (double click) Sound, Video & Game Controller OR System Device > System Speaker. also, take note of the Troubleshoot tab. If still it doesn't work, I think you have to reinstall the sound driver (from its motherboard software CD if it's built-in type). best regards
hi ,first unplug the monitor both from mains and the comp, keep it that way for some time and then check, and secondly the clicking sound might be of the relays used in the power curcit, check the relays,let me know
Typical failure is High voltage supply. Can you hear a high pitch whine or the relay click on and off? You will need some test point reffence voltages for the board and confirm you do not have a damaged VGA cable. It is not easy to give step by step via forum. Google "monitor repair", there were a couple good general guides that are printable. If youe high voltage tranformer (flyback) is gone, do not go any further. Price of a monitor flyback is $65 to over $100 depending on model.
