Definitely a problem with the monitor. If you can get the back open
then look at the main board and the power board. You will want to look
for puffy capacitors. Instead of a flat top it will look puffy like its
If you find any like that then you need to replace
them with new capacitors that have the same Uf rating and at least the
same voltage or higher.
This will take some unsoldering and
soldering skills. Make sure the stiped edge gets aligned with the
striped edge on the board.
If you replaced them then the monitor
should turn back on. If it doesn't then its a screen problem and you'll
need to get a new monitor.
When the LCD monitor display flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp. Check out LCD Parts for parts, service, and DIY info. Use this link to their WEB site :- www.lcdparts.net
The problem on your monitor is a bad power supply. Because of heat buildup in LCD monitors parts called capacitors overheat and blow out. You can go to our web site at: www.ccl-la.com/badcaps.htm and see what to look for. If you open your monitor and see blown capacitors that look like the pictures on our site then replace the bad ones and you should be back going. Email me if you have additional questions or if you need to get the capacitors, we carry them in stock.
LOOKS LIKE A BURN SOLDER !! , open the monitor , check the PC BOARD around the transformer area , look for burn spot or cold solder , RE solder it , try again , hope this helps please rate solution and thanks AJ
