Then, i have continued to find the problem, until i found that the 2 terminals of the antenna jack , J6_RF , are shorted!
It looks that the whole FL4_RF is shorted, every pin is shorted with every other.
I should now desolder FL4 to see if the short disappear or not, but.. if it is FL4 the problem, i don't know if it's enough to jumper it.
Anyone has an idea of what is used for ? Attachment 301938 |
This filter you show is for GPS not wifi/bluetooth and it is normal that it short.
Here try this if not fix try other antenna if same reball replace wifi module.
