no such thing as "unsolvable"
I'm a firm believer that there is no such thing as an unsolvable problem - all that is required is the willingness to learn and ask questions, time, and money.
with all three of those - you can fix anything. with any two, you can fix most issues, and with any one you can fix many problems
without any of them, you are on a hiding to nothing.
just my tuppence worth.
