where i work, we are required to return the bad parts in a bag on COD repairs. we also don't inflate the bill. inflating the bill is bad business. we also have estimate fees. if we open it up and find out what's bad and you decide not to have it fixed, it's $35. we have 3 labor rates for repairs, $50, $80, and $120 depending on how long the repair takes. we call the customer with an estimate before ordering parts. we don't quote estimates on lightning hits or water damage. everything is in "black and white" and we have very very few irate customers and lots of happy ones. i've been in electronics for over 35 years, worked for a lot of different companies. i've even quit a few when i saw something not right with their business practices. it doesn't pay in the long run to fudge a repair bill. it takes hard work to get a good reputation. it only takes one mistake to lose it.
btw.... aren't those caps a little oversized? it's not generally a bad thing to use a bit higher value and voltage of cap, but the base of one of them seems to be right up against two diode leads. if the shrink wrap on the cap gets pinched it could short against one of the diode leads.....
