Power button blinks - won't turn on

I have a Samsung Syncmaster 150mp. It worked great and then one day out of the blue, it won't turn on. Let me crrect that, it turns on but nothing happens. The light under PC turns green then goes off and the power button just blinks. I've replaced the cord that runs from the pc to the monitor and it does the same thing..

When the power light blinks, it indicates in PC mode that there's no PC signal (depending on the monitor, it could be the sync signals or a combination of sync and video.)

You SHOULD be able to hit the source button to see if the monitor then comes up to allow you to watch another source like the S-Video, Video or TV (ok, so good luck picking up any signals if you're in the US -- but you SHOULD see static and this is probably the best "quick test" for now).

If you see static... your monitor works for most part.

Where you would troubleshoot now is the cable for your PC and the connector to the monitor on both the PC and and the monitor end. These can come loose, get abused and cause solder breaks on the circuitboards within (less common but possible).

Most cable issues I see are just bad cables from extremely tight spaces bending the cable and causing wiring breaks in the connector housings. (unrepairable because of the molded cable end)

Try those out and let me know.

    I have this same problem. Power button blinks; none of the other buttons respond, including the "source" button you mentioned in your solution above. Is there any way to get it out of "pc mode" besides the source button? Any other helps? Appreciate any help. Thanks, Jim P.S. Willing to try soldering replacement switches etc.

Samsung SyncMaster 731B Monitor blinks on and off.


It sounds like you have bad capacitors on the power supply board. The capacitors in the power supply filter the power, when they fail the power supply can not maintain operation. The blinking is caused by the power supply starting up, shutting down and restarting again. The monitor is repairable, you will need to replace the capacitors on the power supply board. 8 capacitors will need to be swapped out. Here is a link to a repair kit with the correct parts.

Samsung SyncMaster 150MP Monitor does not have any usb connection or built in personal video player it is only tv and pc monitor. I recomend you watch your files over a pc connected to this device. you need a device that has DIVx capability to watch video files such as .avi.

I hope this was useful..

Hello,

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

I hope this helps, if so please rate my solution.

Popping static noise SyncMaster 150mp


Are you still having problems with this monitor?

I posted about a "clicking" sound that has to do with failed capacitors near the speakers' amplifier IC.

If this is your problem, let me know - it can be fixed.

Clicking sound


I found the problem.


I've written up a small article on my website detailing the fix but in summary here:

Electrolytic Capacitors C826 and C835 go bad because of the heat stress applied by the audio amplifier right below them. Replacing those capacitors fixed my 150MP.
