Da brief inspection/diagnosis dat
yer local repair-person may perform on your mildly-malfunctioning equipment for free, if you ask him reeeeeaaaalllyyyy nicely.
If you either purchased
da not-working-quite-right device at
da same "sales '
n' service" shop from where you're requesting
da help wif said cranky contraption, or you do a good amount of business at said establishment anyway,
da staffpeople there may be a lot more willing to favor you wif a "gratis glance", since you'll already be a "preferred customer" whom they want to keep happy.
