Does it give any sound or completely dead?
DId you try to check all connectors?
Since all the ICs in the PCB are glued to the PCB you would not need to use hot air, but my suggestion is - try to use it. But not too much, and keep it over the ics only.
IMO it just some IC contact with PCB was lost due to the hit.

the glue has to be on all sides of the ICs That's my zero doubt that one of the ICs is not. but seems to be completely glued to the PCB.
