A little bit a self diagnosing could go a long way and save some time and money. Like my crappy home router, the solution to many modern electronics woes can be distilled down to simply this:
Uunplugging
Wait 15 minutes
Plug back in.
But seriously… you should try this first, it might actually save you a trip. If that doesn’t work, you may want to consider following the troubleshooting guides on the manufacturer’s website. A lot of known issues can be solved with a factory reset.
We get many consoles brought to our shop that have been misdiagnosed as having a laser or drive problem when in fact the problem is with the game media itself. Try a different disc and ensure that it isn’t scratched.
