Hello friends of me I repair I have to repair a squaring machine that I had never seen which I found the electronic board with a burned varistor, a fuse and two inflated capacitors which being an industrial machine I do not know what price to charge I am fond of electronics and repair many things but this took me by surprise and I do not know what price I can charge for the repair the machine is costing an approximate $ 180,000 new here in Argentina if someone can pass me the value of a repair of these I would be grateful atte ariel

It is usually considered reasonable when calculating the price of a repair between 10-20% of the price of the product, for a TV, laptop, etc. It would be applicable, but in your case I think you should do it for the approximate price of the source or the plate you have repaired, and depending on the hours of work that have taken you.
