My samsung syncmaster 225bw when turned on would have the back light stay on for about one second, then go black, with or without the signal cable attached to the computer. After your screen goes black, shine a flash light on the screen to see if you can see any images
I repaired my monitor by replacing several bad electrolitic capacitors on the inverter board. These capacitors had broken bulging leaking vents on ther tops. There were two 820uf 25v and one 330uf 25v electrolitic capacitors that had failed. I ordered from Panasonic FC series low impedance electrolitic capacitors, However, the 820uf was not curently stocked and had to be backordered, so I got one 1000uf and one 680uf to replace the two 820uf which were in parallel on the board. There were two 680uf 25v on my board which had not yet failed, so I also replaced them. On my monitor, the capacitors can not be longer than 20mm, due to space limitations. These electrolitic capacitors have a life time between 1000 to 5000 hours, so when you order get a few extra of the ones that went bad.

Hi, I have Samsung Syncmaster 226cw monitor. When i turn it on the screen flickers then goes black. If i do this a few times it sorts itself out. During the flickering there is a high pitch buzzing...

I have the identical model with the same problem, I pulled it apart and the power supply/inverter board are one, and descovered the problem was in the inverter transformers, { 2 in all } because my monitor is 3 to 5 years old I felt replacing the whole board assembly would not justify the cost since something else could break down, I opted for a new monitor.

Samsung SyncMaster 920nw suddenly went black now squeaks/flickers

The 920nw did have a 3 year warranty on the unit but they will be out of warranty now. The flickering power light is an indication of a failure in the power supply board. When the board fails it can't start up correctly and the power shuts down over and over so you get the blinking light and no display. This is a very common failure point on all LCD monitors after a few years of use. There are parts called capacitors on the power supply board and they filter the output power. When they fail the power is not properly regulated and the power supply shuts down and tried to restart so you get the flashing. Here is a link to a repair guide that will show you how to dis-assemble the unit and then what to look for and replace to get it back up and running again.

The repair guide has pictures and videos to guide you through the repair.
I hope this helps, if so please rate my solution.

Syncmaster 226CW showing picture only for a second + flickering


Call and get the RMA for your monitor, the problem is in the power supply and it will only get worse. This is a common problem with LCD monitors after 2-3 years of use.

Its the capacitors on the backlight power supply. Samsung installed crappy ones and they blow up after a year or two. Change out the caps and you're good to go
