Green light continously blinking in samsung sync master 753s


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 )

Samsung crt 591s blank problem


This eventually happens to all CRT monitors. Either the flyback transformer or some other critical componant has failed, and the screen cannot produce a picture. It might be an easy fix, but it would be better to get a new one.

Blank Screen while Green LED is Blinking.


It's because I accidentally plug the cable to the built-in graphics card port. Now I connected it to the right one and my monitor is working great!

Samsung color monitor


This problem may arise from monitor as well as from cpu.
First of all check it by unplugging the VGA monitor cable.
This will display the "Check Signal Cable" depending on the model of the monitor. But a message will appear rolling on the screen, if it is not a very old monitor.
If the message is appearing OK and green light is continuously on, that means ur monitor is working fine.
The problem may be with VGA cable or with the booting of CPU and probably the RAM. Recommended solution is to reconnect the RAM and then try, if u think u can do. Otherwise call a hardware engineer.
If there is no message and still the light is turning green and yellow. That means the problem is definintely in the monitor.

Thankyou,
Your well wisher
