TBS UNIFY REPAIR | no output power

HI,
This is the repair of a UNIFY PRO vtx that suffered from a loss of power (vtx seems to work but at every output power level the range is zero).
It is a common issue with these video transmitters, with more reasons but the most obvious being powering it from 12v or LIPO voltage instead of 5v (there are 2 versions, one for 5v and one HV witch can take LIPO voltages with ease). Another reason can be damaged antenna or by powering it without an antenna that leads to too much current draw from the LDO.
PART : AP7365-WG-7
I hope i said it all, if not please ask in the comment section.
Thanks for watching.
