Hello,

This usually indicates a power supply that is about to fail. Heat buildup in the monitor case causes parts called capacitors to overheat and blow out. Check out our web site at: www.ccl-la.com/badcaps.htm We have pictures of what the blown capacitors look like. Open the back of your monitor and look for the blown caps. Replace all the ones that look like the ones in the pictures and you should be back up and running. We are working on a step by step repair guide that should be posted on our site by the end of the week. The values you need to get are going to be marked on the sides of the ones you take out. Be sure to reinstall the new ones with the polarity stripe going the same direction as the old ones come out. You can order replacement parts from several places on the internet or we can supply them for you. You will need to use high temp caps that will be marked 105c, these are not available from Radio Shack. If you use ones that are not rated correctly then you will have more issues in a month or two. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping.

Either buy a monitor cleaning cloth, or use a soft cloth with a little bit of lighter fluid. The lighter fluid will evaporate, so don't worry about getting it off after you're done.

this is very frecuent in all monitors or tv's lcd .... turn on 3 seconds and off the capacitors need to be replaced y sugest a technician

Speak more about the problem, do so we can help you! Thankyou my friend!

Hello,

The flashing light is caused by the power supply not starting right. Because of heat build up in the monitor case parts called capacitors have blown causing the power supply to fail on start up so it keeps trying to restart. If you can solder you should be able to do the repair yourself. Go to our web site at : www.ccl-la.com/badcaps.htm and look at the pictures. Open the monitor and look for the bad parts, replace any that look like the pictures and you should be back going again. Be sure to replace the blown caps with high heat rating units rated 105c. These are not found at Radio Shack, you will have to get them from a supply house or the internet. We carry them in stock if you need us to supply them for you. Be sure to resolder the replacements with the polarity stripe going the same way as the old one comes out. The values you need will be marked on the sides of the ones coming out. If you don't want to do the repair yourself we offer a repair service for $35 + return shipping. If you have additional questions just contact us at our web site.

Hello,

Your monitor has a common problem, the power supply board is blown. Because of the heat trapped inside the monitor parts called capacitors have been damaged. We have a repair guide on our web site for the Samsung 214t series and your 204 is very similar and they use the same parts to repair them. Check out our site at: www.ccl-la.com/badcaps.htm

try on different computer and see if it still happens if it does time for new monitor as they are factory fix only and not worth cost

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Its the poblem of SCREENSAVER which gets activated every 10 minutes.

In Control Panel, go to Display Settings / Personalise - - - - -> In Screen Saver select NONE.

Your problem will be solved for sure.

Hello,

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.
