My monitor has these boxes on it. I took it apart and looked at the capacitors I don't see anything wrong... Any help would be appreciated!

Re: dell 2408wfpb
Perhaps a picture of the insides would be useful to us?
The one you have provided is out of focus.
Try the monitor on another source/PC/Laptop
Try with a different cable vga/hdmi/dvi
Try a different monitor on the current source
What were you doing before it went like that.
Have you soldering eqipmment and multimeter and can you use them.
Which threads have you already read?Please upload pictures using attachment function when ask for help on the repair

Re: dell 2408wfpb
I repaired 2 of these Dell 2408wfp's with a similar looking problem about a year ago. In both instances it was the T-Con board. Basically the lcd screen showed blocks, and distorted vertical lines. I'll post the pics of them. I had to get the part number from the T-Con board. Managed to find some place in China that sold them (can't remember which outfit). And they took 3 weeks to arrive. I think they were $35 each new. Maybe they are more readily available now.Attached FilesComment

Hello everyone,
I have been having some difficulties reviving an old Dell 2408WFPb PC monitor that I received for free. When I first acquired it, the backlights of the display were on but alas no image was showing. After extensive research on the topic, I went ahead and purchased a new t-con board for the monitor. After installing the board, I was then presented with a new screen that was half black and half green (more so black). I have been unable to figure out what to do next as I have limited knowledge of display electronics. Might anyone on this forum have an idea of what may... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hello everyone,
I have a Dell U3419W Monitor that has some thin stripes on a part of the screen since Tuesday.
This lines cover about a third of the screen and appear for 2 seconds before disappear for another 2 seconds.
This repeats the whole time. I have not opened the case yet cause I had no time, but will try to fix it on this weekend. For me, it looks like a problem on the TCon... Am I right?
Does someone have seen this before?...
