Monitor not getting power

I have a monitor that i am trying to fix for someone or at least diagnose.

First time I plugged it in, i got no power, the green LED did not going. After trying a different socket, I got the green LED to light up for 1 second and then nothing again since then. I can hear it make a noise each time i initially plug it in and unplug it.

I took apart the monitor to see if I could notice anything unplugged and nothing looked out of the ordinary.

Any suggestions?

Re: Monitor not getting power

Could you describe how you got it apart? i've got the same problem, and i feel like i'm going to crack it just to get it open...i've mostly tried pulling the back off from the bottom after removing the 2 screws

No power at all

If your monitor doesn't turn on, and you are sure of the power supply (some plug directly into the wall and some use a power adapter), then you can assume that the monitor has failed.
You can fix it (replace the power supply in the monitor itself or possibly the on/off switch), have it fixed by someone who knows how to do this, or buy a new monitor.
First, of course, be sure the problem is your monitor and not the computer. If the monitor light turns green and then yellow, you can assume it's the computer. If the monitor light doesn't go on at all, it's the monitor.

I m having samsung SyncMaster 753s 17" black it

It sounds like your monitor has bad capacitors in the power supply that are slow to charge up. Repeatedly turning the power on as you do eventually charges them to the point where the monitor comes on. It isn't clear from your description if the monitor works properly when it finally comes on, so I don't know if it has other problems as well.

The shop you took it to probably didn't want to be bothered trying to diagnose the bad parts, because it's not economical to repair. They would need to charge you more for the repair parts and labor than the monitor is worth, and it's impossible to tell what other parts are ready to fail because of their age. I don't blame them. New LCD monitors are inexpensive, and it would probably cost less to buy a new one than to fix your CRT monitor.

My suggestion is to replace the monitor.

My monitor just shut off and won't come back on and it looks like its not getting any power at all. Does it mean that it blew a fuse or is it something else that might cause this?

Check to make sure the monitor is securely connected to the computer. If in doubt, disconnect the monitor from the computer then reconnect. Try powering up and see if that fixes the problem. If your machine is a desktop system, the graphics card may be loose, so you might want to have someone check that. If those two things check out ok, then check the monitor power cord by plugging it into a different outlet socket. Good luck!

The monitor was working one day and the next day, it would not come on, screen black. My grandson has had the monitor for almost three years.

I'll hope for the best and assume the simple fix first. Check the plug at the back of the monitor to insure it wasn't pulled out slightly. Sometimes, moving something around can cuse the plug to lose proper connection.
Also, check the power source to insure that you have power to the unit. We had a lightening storm recently and the power strip surge protector did it's job. I turned it back on and everything powered up again.
I hope this helps... Good luck!

Apple monitor 20"

i’ve been repairing lcd monitor for awhile If you can or know someone that can take the monitor apart. check the power supply for caps that are bubbled there are bad. If you know how replace if not and know someone that does have them replaced. that should fix your problem the inverter circuit may or may not be on that power supply. if the two pair of lamp wires are plugged in then it all in one. replacing the caps work about 80% of the time. i would check and replace.
please let me know if this helps thank you.

It isn't getting a steady, usable source of power, you can try to diagnose this your self but it will be a power issue INSIDE the monitor within the circuit board

It's probably your dc power supply.

Mine would blank just 2-3 seconds after power-on.
I pulled this monitor out of the garbage - someone threw it away. I found any old 12vdc power supply I had laying around (1 from an hp scaner 1250mA, another rated at 600mA) neither could supply the current (amps) required to run the backlights, therefore backlights shutdown, monitor goes blank--monitor stilled powered on, but black.

I tried all of the disassembly, re-solder various solder joints on the LCD Inverter board and removing the heat/magnetic shield from inside the back cover of the monitor. Nothing worked.

I bought a Segate 80gb external hard disk drive that came with a 12vdc power supply, looks like a typical laptop power supply, rated at 3A (3000mA). Plugged it to the monitor, it powered up, and it works flawlessly.

It sounds like either an internal wire is loose, or possibly in the connector to your video cable. Make sure the connections for your video cable are tight both at the computer and at the monitor. If they are, try a different cable (cables are much cheaper than monitors, always start with the easy solutions first). If the problem is internal to the monitor, then it is up to you to decide whether to try to diagnose/fix it yourself, or buy a new monitor. The cost to pay someone else to fix it is likely more than the value of the monitor.
