Re: Dell 2408WFPb / 2408WFP - No Power

Hi !

Back from the X-ray photography. No big deal. Every solder ball seems nice and good. Soooo .... the problem is elsewhere. I get it back today, I'll have a look to the board under a microscope.

Is it really impossible to get a service manual for this screen ? I can't find one, even a non-free version.

eaarnoudse,

I asked for an X-Ray photography of the BGA chip at my work. I will update this thread as soon as I can got it. I hope I'll be able to see some failed solder balls.

Hi ! Did you try to reflow the faulty chip ? I've quite the same problem.

With plugging the screen I got :
-> Green Led, Orange led, Green (flickering) slowly changing to orange.
-> No Backlight
-> Power supply Ok

Before this, it was difficult to start it up (Had to plug/unplug it multiple times). Sometimes, the screen went black for 1/2sec and back on.

The radiator of the chip you describe is warm after few minutes plugged in.

It definitely...
