Re: DELL U2410 problem

Today I had some time (Canada day here!) so I took some time to dismount the monitor again. Like you said Meinfreund, I manage to get the monitor turn on while dismounted and I saw on the same pole that I had previously cleaned that there was an electric arc forming in one of the graphite rubber (video enclosed in the attached zip file). I removed the two rubber and remarked that in the one forming the arc, the hole was much larger. Sorry, I took many pictures but forgot to take one of the rubber.

I've made a simple drawing. On the right you...

My second tube was carbonized like yours. I gently sand it up until it was cleaned. I power it up as is and it stayed lit for more than one minute but I had to hurry to my son's soccer game. When I returned the "screen saver logo" was gone. I cycled the power and the picture stayed for one or 2 minutes.

Re: DELL U2410 problem

MeinFreund, Thank you for the link. I will dismount it tonight and check if it's the same issue.

I did the flashlight test as you mentionned and yes, I still can see the menu once the backlight goes off.

I will dismount it as soon as I can after I finish my work and I'll keep you posted. Thank you for your help!

Hi MeinFreund,

It's been a long time since you posted the above message, but did you succeed in repairing your U2410. I have a similar problem.

I have 2 U2410, on REV.A04 and the other, REV. A06. Unfortunately, my 3 years waranty on the first one I purchased (the A04) just expired 9 days ago :-(

When I turn it on the I can see the image displayed by my computer. Then, after 5 or 10 sec, it goes black. The power light remain ON. If I cycle it off/on, I do get the image for another 5 sec. If I unplug the video cable...
