It is completely burned. I just hope that it is only this component, because troubleshooting this thing with the coating is a nightmare...

weird, I can, will post it again hereheatsink|none|heatsink

Hey! Just opened my faulty module and found this component burned, anybody can take a look to it? it should be a resistor and since it is going to ground the measure should be direct. Thanks a lot!heatsinkcomponent|none

Pics.. for those interested

Yeah, and I only found out because I was desperate and started removing everything... The picture is not a scan, it is only the first layer disvovered with either acid or sanding. I have some discovered traces after removing the paint from top and bottom, but not yet sure if there is a fifth...

Found it! Capacitor C18!! Pfff.... now re assemble and find the two DC DC converters in aliexpress... crap! Thanks to all for your suppor!

Nothing conclusive yet. I removed U5 and U6 and added L1... and still short between 5V and GND...I am desperately searching for the 5V path to see if I can isolate the issue and will start removing all the capacitors but this does not look cool...U5 was difficult to remove even with soldering...

I must say that RDCF550 schematics are quite accurate, someone said on another forum that he would try to do an X-Ray on the board, which would complete the schematics but he didn't. Lets see If I can find out something today!

Well, I have this need of bringing back to life broken items, and I found this as a nice challenge ;). On top of that I can learn a lot from it, and eventually bring some relevant info to the forum!

It is at least a 4 layers board.... I can attach some pictures later if needed, but below the top and bottom layers there are another two ones... at least, and I think that there might be a 5th one...

Hi! Both commnets are really helpful and appreciated! I will check the resistance, but I presume that it was 0 ohms if I remember well. And jarance, indeed, I see that the main issue with the voltage could also be the fact that L1 is not present. I will receive a replacement this week. In the...

Thank you so much! I have checked all the pins and I see no shortcut between ground and the output of that one (which is not directly 5V) So it looks to me that: Either one component from ground to 5V is grounded, Either I am not measuring correctly Either there is no problem and I am just...

Hi! Thanks N017RW for your reply! I found the 3.3V DC DC converter, U6, but not the 5.5v one.. is it U5? all the rest are using the 5V as inputs if I am not wrong..

Hi Guys! I am working hard to bring one phantom 2 to life after a crack on the middle of the PCB. The crack was clean, and at first I discovered a short between 12v and ground due to it. I cleaned that, and thatnks to the great contribution of RDCF550 I managed to follow almost every path...
