Question about Samsung Televison & Video

1 Answer

I just got a monitor, samsung LS19GSESS/Xaa from my friend cause he got a new 22" . However when i tried it on my computer it doesn't work. So when i plug the monitor onto my video card, 5770 brand new! it doesn't display anything. But when i turn off my computer i see the computer test thing when it says "blue, green and red." sooo i'm assuming the monitor does work but it doesn't work when i plug it into my video card and turn on my computer!!!

    bad caps? maybe :S seems common from what i have seen around the net though i am a complete novice in the lcd line of fixing but sure gonna try

  • coszmic101be Mar 11, 2011

    not to sound like a noob :S just asking if the backlight was done lets say would it still show the no signal across the screen when no vga pluged into it? seems it just wants to go funky like that once the vga is connected it does display the no signal and on self test says ok ....just wondering really appreciate your time just trying to clearify before tossing it to the curb......few caps that expensive? i truely not a clue on that yet

  • coszmic101be Mar 11, 2011

What you are seeing is the monior test and adjust features. If your old monitor worked then the computer is not at fault. Try this: Boot up your computer and while doing so continually press the f8 key, ever second or so, don't hold it down, just keep pressing it. eventually (if the monitor works) a screen will pop up (assuming windows operating system). when and if you see this screen choose the option "start windows in SAFE mode" if this works just wait till it boots up. After it boots up and tells you its in safe mode, right click somewhere on the screen and choose either "screen resolution: (if windows 7) or "settings if windows XP. change the screen resoltion to the lower choice 800 X 600 Or somethign close to this. Now reboot again in normal mode. if the monitor now works you can go through the process again to set the resoltuion higher, 1280 by ? or something. let me know if it works.

    I had a 19in monitor that quit working, it turned out to be the back light, when you turn on the monitor look closely at the back, and see if you can see the florescent light that should be glowing. If its not it might be fixable if your willing to spend 60 to 120 dollars, it is the capacitors on the electrical board inside the monitor. they can be replace, but like i said, it might not be worth it, and since you got the monitor for free, you might just as well dump it.

    your right, if you had no back light you would not see the "No Signal", I missed that . as for the caps, I took mine to a guy that does electroiic bench work and is set up to do it. I am not set up for that. the caps are cheap, its the labor to get to the that is the expensve part, and if your seeing the "no signal thing' then the caps arent bad anyway. I don't think I can help you any further. sorry.

Samsung syncmaster 2220 blinking blue light and no image display

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

What would cause dark blurred display all modes?

I suspect the monitor is dying. Unless it is under warranty, you may need to replace it, as getting it fixed may cost more than a new one.

Hi there, if you are experiencing something like a white cloud spreading across whole LCD panel, then unfortunately it has to go for a panel replacement .The panels are still expensive so I personally suggest to try buying a new unit cause of the warranty. Cheers.

This type of problem is caused by a failure of the filter capacitors on the power supply board. The board is easily repairable, you just need to replace the defective capacitors. It will require a little soldering but anyone can do it. Here is a link to a repair guide showing how to repair the board and what parts and tools will be needed to complete the repair. I hope this helps you out.

Hello, there may be several reasons for this;

1. Confirm that the monitor cables are connected properly
2. Do you have a graphics card installed? if so i guess its not seated properly, you should power down and confirm.

3. Does your computer boot up? you may have to confirm using another monitor, see if you can get into the bios or something. If nothing comes on screen then please check your memory and hard-disk connections

4. Check all other board connections, you may have overlooked something

Hope you resolve this soon

They only include the Win7 driver on the CD. I'm surprised it doesn't work with Vista. Did you try going into the HF225_win7 directory and clicking on infinstallWIN7?

The monitor menu doesn't work with the keyboard. You have to press a combination of the three buttons to the left of the on-off button. It's not very intuitive.

Weird colors!

Normally this happens if the plug at the back of of the monitor or the computer loose. Try to secure that cable. If they are secure, check the pins on the ports at back of the monitor / desktop or the cable. I also suggest that you try a different monitor cable.
