My son was hitting buttons on my Onkyo TX-SV545 and now the front right & left speakers are not functioning. The center speaker, subwoofer and surround speakers are all working. I'm not sure how to fix it.

Try swapping the connectors for front-left and front-right (just swap right at the back of the amp)
After the swap, does the front-left speaker work, and now the front-right is dead? If so, then it's a problem in the amp. If not, then the problem is in the wiring and/or the front-left speaker itself.
Post back here with your findings, and we'll troubleshoot whichever part of the system is broken.

You didn't state it but I assume the other channels are functional?
The auxilliary channels are generally lower power and may even be serviced by a different voltage than the main amps.
If it is so designed, you may have something as simple as a blown fuse for the main amp supply.
If the aux. channels are equal in power, the power supply may still be dividing the load so a fuse still could be at fault.
The unit could also use integrated power amplifiers in which case, if two channels are operating from a single module it could be a module failure.
I don't see much chance of anyone repairing this system without examining it in the first person.
