No white light but I've got green light and no screen
It VERY much sounds like controller is dead. Ive had the same thing happen. In my case it was not the bridge or pi because I took a known good bridge and pi from another controller and plugged that into my faulty controller and got the same result and that was a :
1. Power with blank white led screen
2. 1 green led controller
=
Dead controller.
The cheapest fix is to use a controller from a neptune. I beleive this is confrimed that the neptune controllers DO work with our pi and bridges. I dont know if more needs to be done or not. I believe neptune controllers can be found cheaper than Titan controllers on EBay.
I have your exact same problem. If I get time, I will diag mine. It could be one of the surface mount capacitors. I have a capacitor wizard that can test "in circuit" capcacitors and resistors. If I can get it working, Ill post how.

a controller from a Jupiter and a Saturn or Mercury (4 port or 6 port) is also supposed to work. I just put a clone titan bridge with pi 512mb B+ in 2 days ago into a Neptune controller...it works just fine...anyway IF you can find such on ebay. But had no issues with the Neptune 6 port board at all. (ya kinda cringe when you turn the psu on..but no boom...) was easy peazy like assembling some lego's
Was surprised. (knc equip being evil and all)
