$210 to repair, cheaper per year than replacing
Over the 3.0 years this device still has, the repair works out cheaper per year than buying new. Two things can still change the answer: whether the failed part is the first of several to go, since a device that has already had one board-level failure often has more coming, and whether anything else on it is close to end of life. Ask the shop what else they saw while it was open.
