unfortunately my daughter decided to charge my saber but used a wrong charger and therefore overcharged. As you can see the board has clearly some burn marks and I would really love to save it somehow rather than spending almost 80-90 euros for a new one.
Can you guys tell from the picture if there is a way to repair the damage? Is the burned out part a overcharging protection? If overcharged is the battery 100% bust or not (battery says it has a overcharge protection too…) ?
what could also be is that the board got damaged by the too hot battery? In the casing they are very close together. But you can see that the board at least has burn marks, I am not sure if this means it is fried oder not though.
Haha yeha the sd card holder just fell off … can’t say I am happy with what crimson dawn shipped here. Anyway there are 4 cables 2 for charging + – and 2 for K+ and L+. It is a one button system if this makes sense?
In general, if the PCB is fine, all the components on the board can be replaced.
The more pads the components have, the harder it is to replace though.
In you case, two components are obviously damaged, and one is obviously missing: Q7, U60 and D62. However, there may be more components that are broken, just less obviously so.
You can use the partmap in this thread to identify which component is which:
That thread also has a link to the BOM, which specifies what components to use.
Note that some components can be hard to find. In some cases you can replace them with other components, but that can be tricky, depending on how much you know about electronics.
Once you have the components, you will need a hot-air soldering station to do the actual replacing of components. Then you need to test if the board works and figure out if any more components needs to be replaced.
I do get asked from time to time if there is somewhere you can send a board to get it repaired. Unfortunately, so far nobody has taken up doing that on a regular basis, and it would take up too much of my time if I did it myself.
The Proffieboard V2 design is getting a bit long in the tooth, which means that in addition to the chip shortage, some components just has to be outright replaced because they don’t make them anymore. Not sure if that is the case for these two components or not though.
