Question about Samsung 226BW Monitor

1 Answer

No picture LED Flashes

Samsung 226BW Monitor, just over a year old and it started a few weeks ago, at the start it would take only 10-15 mins for the screen to work but now I have had power going to it for 14 hours and nothing, it just continuosly blinks the blue LED light and makes a humming sound when the light comes on. Previously when it showed a picture it would never go off and work fine until I turned it off. Any ideas?

I just did this to a friends monitor as well, a different model and not much different in build. I think you might have 3 screws on lower back side of cover. Start your separation from the bottom of the frame.Your power switch will remain on the front frame while the wire will remain with the rest.

HOW TO OPEN A SYNCMASTERNo picture LED Flashes - 2.gif 2053BW

NO SCREWS!!! Assuming that the stand mount has been pulled out..The seam around the screen frame is where you start. The frame has the prongs, the back cover has what the prongs slip over.The frame is coming off first! I got the side to open by finger, then used a small standard screwdriver to pry ever so gently(lifting frame from rearcover). Leave the power button assembly on the frame, pull wire only a little to relax any tension..you get about 3/4" in extra taped to panel. The hard part is done.;) Still holding the frame...Now lift the panel (where the power button assembly wiring goes under panel) with the power housing that is under it as a whole and you will see where the powerbuttonassemble detaches.Remove frame. Now..holding edges of panel into back cover, lift and flip the whole thing over and place panel face down on a perfectly flat surface..a towel on my desk works. Lift and remove back cover.Your now looking at the back of the board housing. The ribon is simple, on the panel end of the ribon, squeez the outer clips together and slide it away against the panel..The secondary tin plate is removable(if you need to remove it), two clips super close to where the sets of wires come around the housing and into the panel. Unhook the 4 plugs(blues and pinks)...Now lift the power housing off of the panel. The big board has the power. One screw to remove a ground plate first. Two screws to remove power board.

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.

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.

Samsung 930BF Problem


I contacted Samsung UK and explained the problem, they ran me through a few checks and they decided to send me an exchange monitor "Equal or better" than the unit I have, stating it would take 8 business days.
If this occurs I will post the results, thanks for your follow up.
