We do specialist electronic repairs for clients in dire straits. Usually
it's only when the units are irreplaceable does it even become
economically feasible to even quote. An hour of my time to examine and
quote the repair is often more than the board is worth for commodity
equipment. It's a bit like forensic data recovery, if you have to ask
how much then the data just can't be that valuable to you.
Its unfortunate, but electronics are so cheap these days and labor so
expensive that even if replacement parts are available it's far cheaper
just to trash and replace.
Things like USB or Ethernet are easily worked around with add-on PCI
cards though. The issue with lightning or power damage though is often
there are seemingly unrelated faults that crop up later from damage to
silicon that is just not identifiable at the outset.
I spent my apprenticeship praying for clear sunny skies, for every time
there was a thunder storm I knew I'd get into work to a filing cabinet
full of toasted alarm panels. Anything with shouting distance of a
telephone line usually went up in smoke. We had a list of semis for each
model that we would replace whether faulty or not as we knew they
generally sustained enough damage to die in the next 12 months anyway.
I've seen TV's with a hole blown clear through the PCB's seemingly a
mile away from the area the lightning came in (power or antenna) with
the components closer to the source completely unaffected. Surges and
spikes do strange stuff.
There are plenty of people around who'll do an assessment on a no-fix,
no-fee basis, but the assessment is generally worth what you paid for it.
