Samsung LCD monitor display / power flashes on and off

"Hi @madmax2 ,

Here’s a link to the section in the service manual BX2250 that shows the flowchart of how to check for no power. (I realize that it is not your model but it should be close enough to be of some help as the model is the same series just a different screen size).

I’d start here and check the the voltages mentioned and see if they stay on etc and go from there.

You could check the capacitors but I’m thinking that it may be more of a power board or mainboard problem as you say the Power light keeps turning on and off as well.

The manual is also handy as it shows how to dis-assemble the monitor to gain access to the various components."
