Turning a radio on it's side or upside down will not create a defect where there was none before. If there was a solder ball, splatter etc that came loose that's a different story. You can always turn it over again and shake it gently to see if anything dislodges.
Otherwise, following your schematic, probe your way from the speaker back to the antenna with a signal generator and see where the signal stops.
If no test equipment, go back over your repairs, one at a time and check them off on a print out of the schematic.
Testing voltages is also a good troubleshooting step..
To avoid creating extra troubles, do no more changes. You have enough to check out now.
