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 SAMSUNG 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.

    I know this is an old post now, but here is some info that will help users with this same problem.

    The fault with the Samsung BW 206 monitor not starting up correctly and just flickering/blinking on and off is caused by bad capacitors on the power supply board. Check out my website athttp://www.normsweb.com/tektips/sam206bw... for full details on how to fix it.

    You should also mention that the replacement caps for switching power supply should be low ESR (Equivalent Series Resistance) type not just the general purpose type cap. Low ESR is a must for switching power supply DC filtering. I use PANASONIC FM or FC series for all the repair works.

Samsung syncmaster 226BW fails to wake up.


If pc not sending it to "sleep mode" or "power save" mode, then unit may need help of electronics technician to investigate the "internal switch-mode-power-supply" that may be going into "shutdown" mode after it detects a "fault condition" with itself or onother circuit.

My 3 yr old Samsung 226bw strobes when switched on


colinfaver, I think a visit to YOUTUBE and conduct a search for longer vid clips of "lcd monitor disassembly" and "lcd monitor repair" for monitors that suffer from the "black screen of death" syndrome and what internal electronic components fail and how to visually locate them on a "switch-mode-power-supply" and possibly replace them with new good ones and with a little luck end up with a working monitor. Your 226BW is SICK, and will probably do same if connected to a different PC with same ambient room temperature. Yes, problem with SMPS/CCFL inverter supply getting a bit tired!! If this was of help to you, please rate on fixya, and do return comment. 12fixlouie Bye for now.

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Samsung syncmaster 226BW no backlight


Look for any bulging capacitors, instead of a flat top they will look "pregnant".

If you see any of those then replace them with capacitors of the same UF rating and the voltage needs to be either the same or higher.

If you dont see any bulging capacitors or burnt parts, then its got be the LCD at that point thats not staying on and the cost to replace the LCD is as much if not more then to just get another monitor.

Flicker, even when no signal cable


Hello,

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 he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues 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.

Does the monitor remain on does it switch off?
Problem seems to be hardware related ie monitor itself is defective.Try connecting to another known working system.If monitor is defective it could be a power/inverter related issue or panel could be defective.

Flickeing like a dying fluorescent light bulb


Actually this is a 'warning' signal from your lcd monitor. The problem is your lcd ccfl lamp are near to their life, need to change. The ccfl lamp like our home fluorescent lamp, when the lamp need to dead, the lamp will flickering first, after some time, will totally off(dead). So, this is a signal for you. Some lcd monitor, when their inverter board are using fairchild inverter ic(oz series), will easily shutdown your monitor when they detected some flickering on your screen (ccfl lamp). If you need more information on repair your lcd monitor please visit http://www.fastrepairguide.com . Thanks.
