Question about Samsung SyncMaster 204B 20.1" LCD Monitor

2 Answers

Samsung syncmaster 204b

My screen just developed a tiny black horizontal line all the way across it. Restarting the computer does nothing. If I refresh the monitor the line goes white them back to black. It is about 3/4 of the way up from the bottom. Whats up? I have the same problem - an approximately one pixel wide horizontal line all the way across the screen 20% of the way up from the bottom of the screen. Any hope?

Unplug the cable, and check to see if any of the pins are bent of missing. If so try to straighten the pin, if that does not work, take it to your local computer repair shop and get a new cable. That happened to an old sony of mine.

ONLY BLINKING POWER BUTTON ON THE DMONITOR. NOTHING ELSE IS THERE.


Hello,

This is a common problem with the Samsung 204B units that have been in service for a few years. Parts called capacitors in the power supply start failing and causing the board to not start correctly. The blinking power button is just the power supply restarting over and over. The monitor is easily repairable, you just need to replace the 5 capacitors that have failed. Here is a link to a page that shows how to open the monitor, get to the power supply board and what to replace.

I have a 204b moniter that the lower half of the screen faded to black then shows two half screens that are filled with so many vert lines that you can't see whats on the screen.


the screen is toast. if its black and not showing whats suppose to be on the other half.if you tried restarting the computer and unplugging the monitor and it is still happening then there is nothing to do. monitors are not built to last long, the cheap ones. it is good to get one with a good warranty because the pixels go out.

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.
