These days there is never any service information available, no circuit diagrams, the boards use surface mount components that once blown up are impossible to identify. If the board and tracks are badly burned, its never easy to repair around that.
It might take a seriously competent person with all the right test gear and decades of experience, a couple of days to trace out the circuit, figure out from scratch how its all supposed to work, identify and source replacement parts. How much would you charge for two days of solid work ?
Customers seem to think it should be a ten dollar repair.
They are SHOCKED if you tell them its not worth fixing, go out and buy another one.
But that is how it is these days.
Not even the manufacturers do repairs.
If something fails in warranty, the customer gets a brand new replacement, and the faulty unit goes straight into the dumpster without anyone even bothering to open it up. Its just not worth trying to fix a thirty dollar item that sells for maybe $300
Its getting that way with motor vehicles too.
My fuel gauge no longer works, how much to fix it ?
Sorry sir, the problem is the computer chip in your electronic dash has a fault.
$1,800 dollars for a new dash module, and a full day to install it.
Oh its four years old ! Spare parts are no longer available for those older models.
Its certainly different to the old days.
