It's some beautiful piece of art
What would be the best conductive material for such high voltage ?
Thanks alot for your help !
PS : I might not be able to update the thread for the next few days.

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
That seems a bit complicated due to the space available.
I think so. That would explain why the monitor switches to a safe "mode", and would correlate elagil's words :
I'm not sure how to do that but I think you are talking about the same idea elagil had on [url=https://www.badcaps.net/forum/showthread.php?t=32268&page=2]another topic[/url] :
I pm'd him, I'd like to have more details on thisRe:...

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Sorry for the picture quality again. Basically, the arcing damaged the part where its touching the metal of the tube.
So you think I can fix this with epoxy ? I never used this before....Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Actually I tried with the inverter tag itself to see how the contact was made, and couldn't see it goes through.
I don't have a multimeter at the moment so I hope elagil can help us on this
EDIT : Damn, we had the solution since the beginning
Now, I will take a picture tomorow, but I'm afraid the faulty connector is too badly damaged......Last edited by prdp; 11-14-2014, 07:15 PM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
And it seems to be a very uncommon design
I don't know how the tags* can touch the metal ends of the tubes no.
Unless this "rubber" slot is actually made of conductor material
Is it possible ?

Yes !Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
I totally understand It's hard for me to explain with my bad quality pictures and new vocabulary for me.
I drew some sort of schema with my amazing paint skills, let me know if that answers your questions.
LATE EDIT : I added a pic to show where the metal end of the tube fits. The problem is, I don't see how it can contact with the inverter....Last edited by prdp; 11-14-2014, 04:45 PM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Not sure to understand your question so I took two more pics.
On the second picture, its the rubber slot upside down.
By "wire" do you mean the metal end of the tube ?...Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Yes there is metal at the end of the tube.
But on [url=https://www.badcaps.net/forum/attachment.php?attachmentid=99115&d=1415980172]this picture[/url] I don't see any space where it can connect with the inverter's metal pegs.
I think I should disassemble another rubber tube connector to figure out the difference but since I broke another plastic attachment, I'm still wondering how I'm supposed to do so. (see 2nd pic)Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)...

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Sorry for the delay guys.
So it seems that this Dell is another design.
I didn't see any wire and to be honest I can't figure out how this rubber thing is supposed to make the connection between the bulb and the inverter.
Have you ever seen somthing like that ?...Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Two quick questions before I proceed to the actual fix
1/ I broke one of the plastic "thing" on the backlight part. (See attached file)
Is it ok to fix it with some super glue ?
2/ Living in Paris, there was no way that no dust comes in. What's the best way to clean it ? (I'm worried to use compressed gas because it could spray some "frozen liquid")
Thanks....Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
I'm not gonna lie, i'm a little bit afraid to do that It seems so easy to break !
What tool did you use to lift out the tube ?
Where is the wire you have mentionned ?
ThanksLeave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Guys, I think I just spotted something very interesting, and you were right since the beginning
On the 1st pic you can see underneath the connectors's plastic protection.
On the 2nd, the corresponding connector compared to another one.
Problem is, I have to idea how to fix/clean it...

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Ok so I've reached the backlight part and unfortunately wasn't able to spot anything suspicious...
Worse, I think that if it's an inverter/backlight connectivity issue, there's not much I can do due to the design.
See the attached pictures.
Maybe it's an inverter issue ?...Last edited by prdp; 11-03-2014, 08:47 AM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Thanks for your help and explanations Per.
Tomorrow I will try to further disassemble the monitor, but I "kind of" already tried and since I have no idea how to and don't want to damage anything I'd like to know if there's any content that I can look at to help me on this part

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Do you need better quality pictures of the mainboard ? Anything in particular you want me to focus on ?
I'll try to take better pictures tomorrow with a natural light.
First of all, let me say that it was the first time I disassemble a monitor -this [URL="http://youtu.be/2oEyzoV4NCQ"]video[/URL] helped me a lot- and to be honest I have no clear idea how to access the bulbs.
I saw your thread about what may be the same...Last edited by prdp; 11-02-2014, 10:52 AM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Not sure they are the numbers you are looking at though.
Here are the other refs :
Main board = 491881200100h
Inverter = 491882200100hLeave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
I can't find the thread you are talking about. Can it be a bulb/wiring issue since the screen is able to display the input signal without flickering for 2 seconds ?
Also, on the 3rd picture of post #2, the "burned" diode's bounds is usual ?
PS : Main board and inverter numbers attached....Last edited by prdp; 10-31-2014, 01:27 PM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
Thanks for your answer.
I posted the pics in post#2 since I can't edit #1 anymore.
I added the inverter picture. Correct me if I'm wrong but other pictures are the main board (power&logic).
I recorded the sound (.zip attached file) :
@~3s : The "click" is the power button, then you can hear a high pitch hissing sound for 2 seconds until the screen shuts down, then a "buzz" the rest of recording.
If I had to say where it's coming...Last edited by prdp; 10-31-2014, 09:46 AM.Leave a comment:

Re: Troubleshoot a Dell 2209wa (will not stay on after flickering)
I'm pretty sure there is an issue with the power board, but I don't know how to find the problem.
Since I don't own an ESR meter, should I replace the capacitors (if yes, which ones?) or can I test the power board with a multimeter ?
Thanks....Last edited by prdp; 10-31-2014, 09:18 AM.Leave a comment:

Troubleshoot a Dell 2209wa (will not stay on after flickering)
Hello to everyone,
I'd like to know if someone could help me troubleshoot a Dell 2209wa.
First minor issue I had a while ago : [url]http://nsa33.casimages.com/img/2013/04/26/130426012213214990.jpg[/url]
Then the screen started to "flicker", and few days ago I could hear a strange noise on the top right corner.
Now the screen will only stay on for like 2 seconds (with a perfect image) before shutting himself down. (power button's led still blue)
I have read retiredcaps's guide but I couldn't see anything on the screen by...Last edited by prdp; 10-29-2014, 11:04 AM.
