I have a Samsung syncmaster 170T 17" monitor that is unable to sync up to video signal from the computer thereby causing a blinking power button light color of amber) not the normal color of steady green. Searching around the internet I found a site that said that a blinking power button, could be a defective controller board? Any help on this one thanks.

Re: Blinking power button
It could also be because there is a problem with the display controller in the computer. Try to hook up another monitor to this computer and see if it comes up. If it does not work with another monitor, the computer will need servicing. If the display does come up, the Samsung monitor will need service. Good Luck

It does sound like a bad monitor, but first! hook a spare monitor to the computer, if okay The SamsungSyncMaster is the problem, caused by the master board which is attached behind the LCD display, the video signals are feed to the main board where the colors are balanced. To repair this would not be cost effective "cheaper to buy new" Now! if the video cable from the computer to the monitor can be detached, sub another cable just to be sure. Finally if both monitors show the same issue, the problem is in the video graphics card of the computer.
The monitor was probably fried during the power outage due to a spike just before the power went out. On the power brick check to see if there is an LED light and see if that is lit when its plugged in. If its not lit up then you may want to try a new power brick, if it is lit up then your monitor is a dead.
Sounds like you may have had a power surge.??
Disconnect power and signal input.
Turn the unit off for 20 minutes or so. Check the outlet against another device. ( Light )
Turn unit on without connection to PC video.
If you get a no signal, you good to go . Reconnect. If you continue to get a flashing light on power button,
Check warranty, get it back to Samsung for repair.
Hope this has helped
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)
