Come on, @james_s.... Live a little!
If there's nothing to lose, then sure, go for it, but in this case:
- Pushing on the IC caused a change in behavior, very strongly suggesting that the problem (or at least a problem) was solder joints.
- There are people out there such as Rossman who are highly skilled at fixing problems of this nature and can do so with minimal risk of additional damage.
- This was a potentially expensive device that belongs to someone else, who entrusted the OP to work on it, probably hoping they could fix it, or at least know when to stop and not make it worse.
Chalk this up as a learning experience. We've all looked back at some point and wished we'd realized we were in over our head and known when to quit before making something worse, but it still sucks. Hopefully the owner of the radio has the attitude that it was already broken and had already decided that it was not worth paying an experienced technician to repair it so nothing to lose.
