I believe in repairing anything if it is viable but it seems to me that most of today's products are so full of possibly unecessary electronics as to make it virtually impossible. I used to repair washing machines and tumblers quite easily when they were simple electrics and basic circuit boards.
I recently repaired a fairly new (out of warranty of course)flat screen monitor by replacing a few capacitors at a cost of £3. My washing machine failed at the same time, new module I was told by the engineer £110. No way I could repair that and It took days to get it as there are about 10 different types for my machine so it had to be ordered. This is the sort of thing we have these days and I think it is done purposly.
