I agree with buddymc, it sounds like a common failure on DELL displays. It may be caused by different causes, here is another example: http://josepino.com/?howto-repair-dell

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of the monitor. If you aregood at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

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.

How long have you had the monitor. It sounds like a defective backlight. Usually when the circuit driver for the backlight starts to go bad, the monitor will blink. If this is the case, eventually the monitor will not turn on at all.

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.

Try to replace C110 and C111 in the power supply circuit. These are 820uF caps and are in parallel. I had slow start and a flicker on this same monitor. Replacing the caps fixed it. Good luck, Ryan

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.
