I have a Samsung SyncMaster 753DF that starts to give me problems, upon powerup the images will vibrate sideways, this continues for about 10 mins and stops once the monitor warmed up. This is not flickering due to lower refresh rate.
Anyone know which circuit / component is the cause of this symptom?

Hi Chin Siong:
Did you try to call technical support for your monitor?. Could be a speaker near the monitor too.....
bye,
Might it have something to do with the degaussing circuit? These are controlled by a thermistor, and normally it heats up in a second and reduces the current to zero. Maybe the thermistor is faulty? The degaussing coil may be attached via a plug to the chassis, if it could be unplugged it would be obvious if it were the culprit.
This is most likely a degaussing circuit problem, or a problem in the power supply, or a component that is causing an unstability in the horizontal scanning circuit. There are many components involved, and guessing is not a recomended way to go. Proper troubleshooting by an experienced tech with the proper service information should result in finding the fault.

Thanks! Looks like it's time for me to get a new m> This is most likely a degaussing circuit problem, or a problem in the
In the flat screen LCD monitors, take a look at the new models of Samsung. They are very impressive for the price. If you want to go for the higher end, the professional series from Viewsonic is excellent.

Hi again Hong:
I have a Viewsonic (CRT) and it is a very good monitor. If you have space in your desk, I recomend you a CRT monitor of 19'' (Quality vs. Price it is much better than LCD monitors).
