Re: Dell 2408WFPb / 2408WFP - No Power
The hexagonal screw from VGA and DVI may probably not have to be unscrewed.
(You can unscrew all by precaution)
But there at least is one screw on the HDMI port and 2 others on the cinch sounds block .
Please look at this photo :

Re: Dell 2408WFPb / 2408WFP - No Power
You have two small PCB on the left ( they are the power supply ) and a bigger PCB which is the main "motherboard".
The first power supply in which you plug the electricity is an isolation transformer and the second one is the AC->DC transformer.
I would just put the working motherboard you just bought on your old monitor, that the easiest and the only solution.
Personnaly I made the same move : I bought a 2048 with a defective LCD panel for 10 € but it was at least displaying something.
I put...Leave a comment:

Re: Dell 2408WFPb / 2408WFP - No Power
My power card(s) were not functionning...
I made several mistake during the repair ( I tested with the command ribbon under the power card by error and it shorted... )
I had an extra one, so not too much bad.
So I changed the fuse, a varistor and and a diode.
And it still does not power up untill I blow heat on the motherboard....
I did not want to try the heating fix so I buy another broken 2408 for 10 €
The display panel is out of order on this one but the other parts seems to work.

Re: Vertical Lines Dell U3014
HI, I have a faulty U301.
I know it is the panel or the T-con board.
( I have a second U3014 to check this and the "panel+T-con" is is not working with the good parts and the good panel is working with the parts of the faulty U3014.
However I did not try to switch the T-con board...
My photos are not so good but I will post them, maybe you could have an advice on the faulty part, panel or T-con ?
The faint vertical white lines are what I got when I switch it on.
The green vertical lines is...Leave a comment:

Re: Dell 2408WFPb / 2408WFP - No Power
Hello, my Dell 2408 does not switch on.
I think the power supply may still be working.
On the main board there is two heat sink :
One a little smallest than the other with "straight lines" and is a little warm.
And the other is not dissipating anything apparently.
Do you think heating more this warm heatsink is usefull ?Leave a comment:

Re: New Members - please post your introductions here
Hello, I try to fix some things that broke ( I successfully changed some bad caps at least once
My last repair was my Dell 2008 ( best monitor ever since the syncmaster 244 T )
I just change the buttons ( thanks EBAY ) a few month ago and voila, comme neuf !
However a few weeks ago it just stopped working.
I do not think it is the power supply as there is some 23V going out from it but I will wrote more in the dedicated subject as soon as I can.
Happy new year 2020 !Leave a comment:
