Having problems with your Computer Monitors ?

Samsung 17 Inch LCD monitor 740N after two years of use developed the following problem. Doesnt display anything but keeps flashing the screen at frequent intervals, but somehow if any of the applications is opened or if kept off for a long time (15 Min or more) under winddows, sometimes start working normal. What is the problem with this monitor?


Answers :

Hello,

This is a classic blown poer supply problem. It happens on LCD monitors 2-3 years old that have been used often. The small case size causes heat to build up in the monitor and parts in the power supply called capacitors overheat the blow out. If you can solder them you should be able to do the repair yourself. Go to our web site at:
www.ccl-la.com/badcaps.htm at look at the pictures so you know what to look for on your monitor. Open the back of your monitor after you unplug it. Look for the blown capacitors and replace all of the ones you see. The tops of the ones in your monitor should be perfectly flat, they may have a design stamped into them but no bulging at all. Replace all that you see that have any bulging. Be sure to use high temp replacements or you will have to do it over again in a month or two. Replacements from Radio Shack will not work! Good replacements can be ordered from several places on the internet or we can supply you with them. The values you will need are going to be marked on the sides of the bad ones you take out. When you install the new ones make sure the polarity stripe on the side goes the same way as the old one came out. If you don't want to do the repair yourself we do offer a repair service for $35 + return shipping. If you have any questions just let me know.

I hope this helps, if so please rate our solution.
