Question about Samsung SyncMaster 2493HM Monitor

3 Answers

My Syncmaster 2493HM wont turn on, The led is solid blue, (unlike most here that flash) with zero light. Sometimes, it will flicker on, and i will here it trying to turn on (it makes like a zapping or snapping noise) also, when it does turn on after I shake it a tad, it makes a high pitch squeak and turns on. When its on its no problem! Also, (this may help) there is no sound when the monitor is in this not on state, but as soon as it does kick on sound is no problem...

Sorry for my bad english but i´ll try to help you because i´ve got the same monitor. You must check the power source there is a problem with the glue you must clean it from the components with the time it becomes conductive. Check the capacitor from the inverter source if you can chage the capacitors by about equal. When you asemble it again don´t foget the protective plastic because it may cause a short.

The snapping sound can be from high voltage arcs over or open lamp circuits, check the connectors for the lamp on the circuit board.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Zdenardi, Good description of problem but you left out two or three important things to tell us!!! 1. Age of unit 2. Is unit covered by Samsung warranty? 3. Approximate total "ON" hours of use has unit seen. Aynway, you or a qualified "cold-cathode-fluorescent-lamp back-lit lcd monitor" technician will need to troubleshoot the units switch-mode-power-supply/ccfl inverter" circuits to determine reason ccf lamps won't "turn-on"!!! Just read my fixya profiles (louie12fix, 12fixlouie) or those of "buddymc" and "budmrtn" for info that will determine if you will fix unit or contract out the repair. You need to know that your symptom is called "black screen" or "blank n black screen" and will only get worse. Just do some free reading on fixya and follow the links you find to other sites. Good luck with the repair. 12fixlouie

It seems like im having some issue with my syncmaster2493 monitor. it will black out and once i wiggle the power cord it will come back on. any help will be apprecaited


Hello,


Your power supply board is failing and when you wiggle the cord it is turning it on and off until it finally starts up. There are parts called capacitors that start failing and it will cause intermittent power issues such as slow to show picture, flashing power button, wavy or flashing picture. The board can be repaired and the monitor will be as good as new. Here is a picture of the power supply with the parts circled that need to be replaced.

On light flickers instead of being solid blue and monitor will not come on


Power off the computer leave the monitor on then go to the computer power button once computer is off and unplug the cord press and hold the power cord down for 5 seconds you should see a blink of light then plug the computer back in and reboot the machine. If this does not work get another monitor to check the video card borrow one to see if it works with a mock monitor if that does not work then it is your video card that is the issue and not the monitor. Change out the video card. if the mock monitor works fine then your original monitor is broken and will need to be replaced.

The front LED flashes red & blue when I turn it on. What does this mean?


LED Indicators - LaCie 2big Network
The LED indicators above the drive bays and the front LED indicate drive status and activity.
During Startup
  • Front LED – blinks red/blue until both disks are powered on, then turns solid blue.
  • Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.
NOTE: If the device is not able to initiate the boot process following disk startup, the front is solid red.
During Bootup
  • Front LED – solid blue
  • Rear LEDs – solid blue
NOTE: If a disk is failing, both the disk’s corresponding rear LED and the front LED will be solid red.
During RAID Synchronization
  • Front LED – solid red
  • Rear LEDs – The LED corresponding to the original disk will be blinking blue and the one being synchronized is blinking red
  • Once both disks are synchronized, their corresponding rear LED and the front LED will be solid blue.

My Samsung 2493HM Monitor wont turn on, the blue light just blinks, then after some undetermined amount of time the light goes solid and all is well. It took over an hour today to start working. This just...


sales660, Monitor should not be doing that!!! Use Samsung warranty if available. Complain about "premature failure". Examine black screen for very faint displayed image with aid of bright flashlight(test all owners of CCFL back-lit lcd displays should know) to determine full or partial SMPS shutdown mode. Read more in my fixya profile for more that you can do. It could be bad capacitors or a thermally intermittant solder connection that you or qualified electronics tech will need to fix if warranty not option. After reading and surfing net you will understand your CCFL back-lit lcd display and how it works. Your monitor no different than ANY other brand of CCFL back-lit lcd monitor in it's basic design and operation!!! 12fixlouie

No picture; no operation except flashing blue lcd light.


Look at the power supply first, look for burnt parts, bad capacitors, etc.
