My old digital piano won't turn on. The AC cord works fine, no problem there. The piano can also be powered with 6 D batteries, tried it but still no luck. It hasn't been used for 3-5 years so it was no surprise. The piano itself was bought on sale so it may be a problem with the components. My friend wanted it and I told him it's not working. He took a look at it and he told me that I only need to replace the capacitors.
There were 15 caps in total attached to the pcb, the markings were still readable so we took note of it. Almost missed it but there was one axial cap attached to the back of the battery case. The markings on that cap is blurred so we can't determine what the value of that cap is. He already bought the other 15 caps.That one cap is the only thing we haven't got.
Can somebody tell us what methods we can use to know the value of that cap? My friend already tried testing it with a mm in capacitance setting but it read none at all.
What should we do?
