Hi My Samsung Sync Master 2253LW woudn't want to turn it on when i turned my cpu on. On the screen it shows digital and analog signal, and the on off light on the monitor is keep peeping.

If it doesn't turn off by holding the power button down for 10 seconds, then it cannot be turned off by the power button alone, like most modern lcd monitors. Most modern monitors goes into standby mode. To completely cut power, you must unplug the power cable.
I've enclosed a link to the install manual for reference.

Have you checked if the SyncMaster is compatible with a Mac? I do not use Macs, so I do not know. In the old times you had to buy everything Apple. You could try looking for an adapter to convert VGA or Digital to Mac Video.

The Samsung monitor is okay, the problem is a compatability issue between the laptop and monitor. The VGA toDVI is the problem you are converting a analog signal to digital, the signal level degrades when that is attempted. If I understand this the laptop puts out the analog signal "VGA" and the monitor has the DVI input, "digital" The only other suggestion is turn off the laptop screen to see if the monitor will work.

did you try other VGA cable? because this usually happen went you using bad cable.

Please check your plug if it is plug in properly or firmly. Locate the switch and turn it on again. If stil persist, try to inspect whether cpu is beeping while turning on. If its beeping something is wrong in your cpu or monitor depending upon the beeps.

check the data cable from the CPU to the monitor, it measn the monitor did not detect any signal from the CPu, or the system is not booting. Good luck

Turn off the monitor first.

Hold down Function button and click F8 key to tell the laptop to send signal to the monitor.

1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )

Up front, i copied this from another site, so kudos to the OP there if this works for anyone...

Hi,
This same problem had been bugging me when I bought my LE37B650, everyone suggested adjusting the delay time on my AV amp but unfortunately mine does not have this function.

Anyway I finally fixed the problem using the following steps

Before you start make a note of your menu settings as you will have to reset them after this procedure

Turn off the TV then press Info -> Menu -> Mute in sequence then turn the TV back on again. This will get you into the secret Service Menu. Go straight to the AUDIO page of the menu. Don't be tempted to fiddle with things in service menu cos you can end up in a right old pickle!

In the AUDIO page you willl notice that there is a time delay set for the internal speakers of 100ms but for some reason this is not set for the external output so all you need do is dial in a 100ms delay there and that should sort the problem. Well it fixed it for me.

Note that as soon as you enter the service menu, all your other standard menu settings are lost and the screen will be set to dynamic for some reason so you have to go through and change everything back after you have done this.

Hope this Helps

This would suggest that you CAN fix the problem with an analog amp.

Also interested to see if a 2 year old thread is alive!
