RX problems
If you find on a strong signal such as an broadcast FM station that you select Amp as "0" and you get a signal and then select Amp "1" and you do not then this is a good sign that the RF Preamplifier u13 (MGA-81563) is damaged. This can happen if you use a stronger transmitter near to your HackRF.
It is possible to replace the damaged IC with simple tools (soldering iron, solder wick). First solder flood the damaged component to remove it, preferably protecting the surrounding. Clean the pads and replace the component:
TX problems
The same component is used for TX, which also can be damaged. Below is an example of the replacement procedure. First remove and clean the pads. This can be done with hot air or normal soldering iron:
For the orientation, you could use the text of the chip itself. It should be "up", pointing to the antenna jack of the HackRF:
