S4469 I assume that's a diode, I didn't find a data sheet that matched that form factor is it d3, d6 or d9?....
Recap / summary;
Thanks! - Jeff
I broke my BB Blue doing something lame, knowing I shouldn't and being just to lazy to disconnect power before plugging in a LIPO. No more boot.The green power led is lit, that's it.Does anyone do board level repair of this card for less than the price of a new BB Blue? If I buy a new one what is most current version of the board and where to buy?The schematic I found doesn't seem to match the board. The schematic doesn't seem to always have component numbers. Here is the backside of the board if anyone can help me decipher manufacturer and version. Here is the legend of the schematic too.

If you have more time than money, you could try to somehow disable the integrated TPS65217C and provide an external 3.3V. Assuming that's the problem at all; it's more likely the load is shorted out than the supply, based on my experiences. Either way, sounds like a big job, I'd rather just buy a new one.
