basic electronics/lightning q

Sadly, the vast majority of consumer electronics today are best replaced than repaired. I once did electronic repair for a living, and when the price for such goods dropped dramatically in the early 90s, few customers continued to repair things like TVs, VCRs, stereos, etc.

However if you do want to check it yourself (or bring it to an honest repair shop), the damage from power surges can simply be a matter of a fuse replacement. (Some fuses are not the snap in type but are soldered onto the circuit board.) But keep in mind that occasionally the damage from a strong surge can be far more extensive.

So depending on the age and quality of the device, it may be worth checking the surge protection components (like the fuse) before scrapping it and buying something new. Unless you were just looking for an excuse to get something new anyway.
