Excellent. So Im going to have this customer ship it to me, and if it is an easy as it looks, Ill try to offer repairs as cheap as possible. Im hoping around $100. If its just removing the connectors, and then sealing the old trace line, and then running new wire, and resoldering connectors, that doesnt seem too difficult. So , Ill have my customer ship me his and see how things go. If its as easy as I think, Ill offer it to you guys for a good price.

Simpler. Just use a 24 gauge wire-wrap wire and run it under the connectors. Works fine, and solves the problem without having to pull the connectors (because the same line always blows)
Just remember to tell the person to junk their Pi and get a new one because that's the root cause.

Thanks lightfoot. So, that brings up another question. Im quite positive that the titans only work with a very specific pi, and thats the original model pi that it shipped with. Ive Actually tried it with a pi 2, and it wouldnt boot. Just a blank, bright led on the controller.
Thanks for the info. Ive focused my research heavily on the boards themselves , non stop for the past year. Ive made it my full time job, as im retired. Here is what I know. Most failures about 80% of the time, is because the wafer gets too hot , and separates from the pcb. Because of the design of the E plate, using 2 screws in the back, and only one in the front, it puts more pressure on the front of the wafer (closest to the fan), and the dies that almost always fail are the first die that gets its voltage from vrm 0 and 1. This die is closest to the exhaust in the back and is easily identified by the small pin hole on the plate.The only repair then is to have it reflowed professionally. Do NOT try a heatgun, because it scorches the wafer, and the many tiny pads, beyond repair, so that when it is lifted professionally, the tiny pads stay with the pcb, and is unrepairable, much like what happens when people use a heat gun on a laptop gpu, it might work for a couple of weeks, then fails. Theres more information , but many people have always wanted to know the ultimate question, and that is: How to fix the .8v dead die issue, and there is the answer. I have had a custom made stencil for the titan along with the professional grade reflow machine. There are still many boards I need to repair and reflow before offering it to the public.
