To go along with previous post about LG Optimus Damaged PCB

[Rude Co.]

Heres the photo link of the damaged PCB in question. Notice the upper
right side behind charger port. Ive already removed the burned out
diode and laid it along the power rail in the photo. What are the
components near to that area and can I bridge anything to get it back
working again? photo link is http://www.flickr.com/#/photos/77872404@N08

I am not going to sign up to Flicker just to see you picture. The diode

did not commit suicide. It died because something further on in the
circuit killed it. The diode was a sacrificial component to stop an
actual fire from starting. You won't gain anything by replacing the
diode without first determining what caused the death and repairing that.

Here is a direct link to your photo (no ads, banners, popups, etc):

Unfortunately I can't make out any of the part markings. :-(

If your camera doesn't have a macro function, then sometimes a scan
will produce a better result.

Otherwise, can you determine where the diode's pads connect to? In
particular, which pins of the charger port, if any, connect to the
diode?

Your "charger port" looks like a micro-USB socket:

Or use a magnifying glass and spacer tube and a few test shots to get to
know the focus range.

I'll second that - sometimes simply laying objects onto the bed of a scanner
can produce excellent results.
