The black splotch your describing sounds very much like something failed on the board and burned the board so now that is a carbon patch that can conduct electric current. With that in mind, I would suggest replacing the board definately

Go to www.partstore.com to get new parts for your set.

What you are describing is pictures burned into the screen, if that is the case! this cannot be repaired. This an imprint left on the screen when the pictures were present, and the only solution is replace the monitor.

Hello,

The picture board on your monitor is malfunctioning, since the power led or button is on, but the screen is black out, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Hello,

It sounds like you have a monitor with a common problem, this series ofWestinghouse monitors are known to have this issue. After a few yearssome LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. When thecapacitors blow out they also damage the driver MOSFETs. If you aregood at electronics repair/soldering you can usually fix he 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 picturesand your monitor should work fine. The capacitors do need to beinstalled with the correct + and - connections, note the stripe on theold one and insert the new one the same way. I am putting together astep by step repair guide for this series of LCD monitors, it should beup by 07/11, check my web site for the guide.

Sometimes you will need to reinforce the whole circuit with new soldering metal as well. Mass produced circuitry sometimes uses very little of the stuff or uses soldering metal of poor quality.
