Looking at maybe purchasing a Dell 30 monitor, but apparently after a move it started ghosting. Is this an easily repairable problem? I am still pretty new at this.
Thanks

Re: Dell Ultrasharp 30" LCD Monitor ghosting...
This will be a tab bond issue.
This is repairable, but difficult; it depends on your level of skill.
See this video: different problem, but same root cause (bad tab bond)

I wouldn't pay much, maximum £15 (around $25) because of the risk of damaging the panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Thanks for the response. Could you elaborate what is involved with the fix?Comment

Re: Dell Ultrasharp 30" LCD Monitor ghosting...
As tom says, it does seem to me like a tape carrier bonding issue. Try getting some freeze spray and spray along each edge carefully whilst the screen is on to see if any changes occur at all. These ribbon tapes are stuck onto the panel using Anisotropic Conductive Film:

Messing about with the tape carriers is VERY risky thing to do and can render your panel completely worthless so I might buy a replacement TCON board from buychina.com to rule that out (but in all honesty it's probably not worth it - even for such an expensive display). Either way this problem is either the TCON or the connection from the TCON to the panel itself. There could be an outside chance that the power to the TCON board is at fault but this can be ruled out with a multimeter.Comment

I will steer away from this one. Thanks.Comment

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...

For the last few weeks I have been trying on and off to fix my Dell Ultrasharp U2312.
I'd read that the 1084-33 voltage regulator on the logic board often needs replacing but they are pretty difficult to find in the UK, plus I don't have the hot air tools needed to replace it properly so I decided to check it instead.
It was getting a 5.16V input and a 3.41V output so that seemed fine so I started looking at the capacitors that I could easily and cheaply replace.
The symptoms were that the monitor would be perfect for a few minutes and then the flickering... -
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...
