The power inverter is the problem but you can repair it yourself. Check out our web site at: www.ccl-la.com We have a step by step repair guide for this model, its the same as the 214T. The repair requires replacing 5 small parts that will need to be soldered. If you don't want to do the repair yourself we do offer a repair service for $30 plus shipping. If you have any questions or need service contact us at email@example.com

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.
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. Check out www.lcdparts.net
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.

Your monitor has a very common problem. The internal power supply has blown a part called a capacitor. If you are comfortable working with electronics and with soldering I can talk you thru the diag/repair. If you are not ready to tackle that we also offer a repair service, about $30 plus shipping for your model. Let me know if you want to try fixing it yourself and we can go from there. The repair will require opening the monitor case and replacing from 2 - 5 parts. You can call me at 318-447-9040 if you have questions.
I have a ln-s4092d that had the same problem after a little more than a year of service. Replacing the main board seemed to fix the problem. But about a year later, the same problem has reappeared. I'm getting ready to replace the main board once again, but I don't really want to do this on an annual basis/
What about the blue circle LED on the power button ? still blinking or not ? For the record I've had some problems with this screen too, sometime I had to unplug and replug my Video Card (and the DVI Cable) and everything was back to normal
