Hi Eev'ers,
While volunteering at the trift shop this fine piece came in. Its a Sharp MZ-721 personal computer. It belonged to a professor at an university who died recently. The machine was placed on the dismantle and recycle shelf because it would not turn on. I managed to get it for free.
I would love to have it working and try some basic commands on the system(that is produced even before my parents met.) So i Tried to get it working. But I stumbled upon an issue. I hope you can help me answer the questions below.
Here is how it went down:
The actual device:
After opening and removing the powersupply:
The 500mA fuse was defective.
Nothing some aluminium cant fix:
It turned on and Beeped!:) The mechanic I am!
Before i could check the video output the PSU started to whisper to me. Before i could understand it it gave a big poof and the magic smoke came out the capacitor:
It ate too much electricity and blew up on me.
I would be delighted to get an answer to the following questions:
I think the capacitor blew up because of the age, the rest of the circuit looks fine. What do you think?
Can I replace this part with any 0.047uf capacitor that handles 220v? Are there any available?
If I should have posted this in the beginners forum my apologies.
Thanks! I will keep you posted on the rest of the repair.
