20 Most Recent Samsung SyncMaster 204B 20.1" LCD Monitor - Page 7 Questions & Answers

Check the data and power cables. One of them might be loose.

It sounds to me like the monitor/TV needs to either be replaced or sent in for repair but there are a few things we can test.

The first thing would be to set the TV to connect a cable line to the TV and see if you can get any type of picture on it at all. (Don't forget to change the input mode)

Then I would try connecting a different monitor to the computer just to make sure it didn't blow out the video card.

If both options work then it is the input on the TV and it needs to be repaired.

If only the TV works then it was the video card on the computer.

If the second monitor works and the TV doesn't then the TV either needs to be replaced or repaired.

Oh and by the way it is normal for the pin to be missing on those cables, that is how they are made.

Have you tried to plug it in else where?
If you did and still same problem then from what you said I was hopping that it wouldn't be your problem, but you will need a new monitor.

I too have a dual monitor Samsung SyncMaster 204 setup. My monitors started flickering, then a week later had turn on problems like your describe. I found a fix on this fixya website and followed the fairly techie suggestion. It worked. I wrote up a .pdf set of instructions so others might also benefit. Hope this helps. Doug

Have the same monitor and had the same problem. The problem is bad electrolytic capacitors in the power supply circuit. Replace C110 and C111 and you will have the problem fixed. The original caps are 820uF at 25V and they are in parallel for a total of 1640uF. I only had a 1000 and a 560 and placed them in parallel. All is good now.

Get this fixed before it takes out other parts in the power supply. Took me about 30 mins. Good luck,

Hi...there!
Sure you can... just go to your toolbars bottom R/H side and look for a Graphic Card settings for example ( Nvidia or ATI settings) Then right click and look for a rotation settings from there just followed the settings... To adjust the display, open your on screen display on your LCD monitor and look for Auto Adjust by using (- +) buttons... Have a nice day!

a common manufacters defect

May be a manufacture defect or the Screen goes wiped out during transportation.

Call to the support for warranty issues immediately.

I had a similar problem on a different monitor and fixed the green sparkles by selecting a lower refresh rate.

Goto cotrol panel/display/settings and set the resolution to 640x480. Make your you are using the video driver from the manufactorer for your video card. Windows generic drivers do not work well for all monitors. When you get the proper video driver you can reset your resolution back to a higher setting.

Yes. There is no vertical deflection. The circuit that controls vertical deflection is bad. This is an easy fix for a TV tech. Take it to the TV repair shop.

The monitor convergance adjustment is out . Is it a LCD or CRT

A horizontal line means that the verticle deflection circuit is not operating. Take it to a TV repair shop this is not a difficult fix for a tv tech

If it works it will only display the same image. There will be a voltage drop, which may cause problems.Which piece of hardware has the dual monitor setting?

change the potentiometre(three broches) and adjust it.
you find it near circuits which switch on the lampes (card has smalls tranformers)

No, it is not the electricity in your house, I had the same problem. Send it back to Samsung and get a new one. I have had to send my monitor back 4 times!

Is this a question?

Screen control on the fly back transformer may be defective. Replace the flyback transformer.

Did it work properly using a VGA (analog) cable? If so, check your DVI (digital) cable against the pictures at the bottom of http://www.datapro.net/techinfo/dvi_info.html.
You probably have one of the two at the left. Each has a different bandwidth, translating to a maximum resolution. The native resolution for your monitor might be marginal if you have a single-link DVI-D cable.
My 204B seems very picky about signal-level. It blinks when connected by DVI, even though it should be fine with a single-link cable, and complains about the settings even though the settings are optimal. Maybe yours is similar. I have ordered a dual-link cable and will try that myself.
