Hi,
Got one of these to fix yesterday. I havent looked at an LED one before so I need a little guidance.
The monitor when plugged in shows no sign of life at all. I have stripped it down and plugged in the power supply and mainboard without having the monitor connected. The big cap is showing 330v and there dows seem to be voltage getting to the mainboard as I quickly tested the voltage regulators. I havent checked to see if they are correct yet which will be my next step.
Pics are only quick ones and as its dark here I had to use the flash but hopefully they will you give you an idea of what I am working on.

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... -
