GTS 450 repair?

Hi guys, I broke a few small components off of the back of my ECS GTS 450's PCB a while back and it no longer works. I have some decent soldering skills and I have confidence in myself that I can repair it, but I have no idea what parts to buy, here is a picture of the damage.

The missing parts are labeled:

LB513
C1019
 
The silk screen is just a designator of the component position on the PCB

capacitor 1019

I bet LB is an inductive ferrite bead, L is a common abbreviation for inductance

what we need is someone with one of these to read us off the codes on the parts

Alright, hopefully someone chimes in and gives us the codes.
 
hopefully someone will chime in on my theory

If LB513 is in fact an inductor it is possible that if you just short across it the card will work. Inductors and capacitors are frequently used for filtering and may not be strictly necessary for the card to function.
 
^ I wouldn't bet on it though. You don't know what the circuit is and having a short might not give you nice results.

Surface mounts can be easily soldered on if you have a steady hand and a good tip. Those pads are fairly large.

You'll need to find someone with the same card... alternatively, you could call ECS and see if you can sweet talk someone into giving you the component values.

Hmm, I might try and solder a little wire on to jump it and see what happens, but I will wait a bit and see if anyone else replies.
 
I got some very useful info from a thread I started on 4chan in /diy/ so I am going to try and replace the missing parts with some parts from a broken motherboard I have. I will report back with the results.
