Re: Dell 2005FPW Power whine and on/off issue.

Prompted by the comment about the wiring ends I dug out the camera for a larger look at the covered sections and it turns out the cabling has melted right where it enters the plastic end cap and there's slight scorching on the plastic harness for both sets of lights....

I measured the pins indicated with a Greenlee DM-200 Digital multimeter and the resistance for the two indicated pins was found out of range for all six sets.

The resistance for the points directly to the right of the indicated pins (For the blue caps) had identical resistances at 3.89Mohms.

Attached are images of the CCFL tubes. They do have varying signs of the dark black rings....

1. Thanks

2. Yes, also uploaded an image of the logic board front (removing it requires undoing a lot of usb fittings). I can take it out if the back needs to be seen for traces.
Also uploaded pictures of two cables that are difficult to have connected and handle the camera for pictures. The power pcb to logic board power cable and the logic board to lcd panel cable, wires and plugs.

3. Yes, it does. If you drop the brightness to 0 it lasts significantly longer. Raising it over 65 brightness results...

During this behavior the power buttons are unresponsive and no image is displayed during its short power on. If you power it off when the noise begins it immediately starts...
