Having problems with your Computer Monitors ?

My 19 inch flat screen KOGI monitor occasionally makes a high pitch sound with a ripple effect distorting the image on the screen. What is the problem?


Answers :

Hello,
\015\012
\015\012I have seen this type of problem on other brands of LCD monitors. The issue is either a bad solder joint on the high voltage backlight transformers or the transformer itself going out. The high pitched sound you are hearing is a high voltage spark. If you have a soldering iron and feel like opening your monitor then you may be able to repair it. Look for 2 identicle transformers these are the backlight ones. Resolder the connections on both units. While you have it open check for bad capacitors and replace any that may have been damaged by the transformers. You can see what the capacitors look like when they go bad at our web site: www.ccl-la.com/badcaps.htm

Screaming acer! Every time I turn on my LCD AL1916W it makes a very high pitch sound. Also when I turn on a game on my PC and the screen adapts to the demand but it then makes the high pitch scream again. Other then the (bothering) sounds the LCD makes, the screen is great! Is this normal? The screen is under warranty so I can have it checked, but I want to know whether it's something this screen just has or if it truly is just mine. Thank you.
