I brought home a HP 1741A oscilloscope from a yard sale. The seller new nothing about it's condition, but for the $5 they were asking, the probes alone were worth that.
When I got it home I turned it on and it blew the fuse, it has a time delay fuse and it blew after a couple minutes.
I opened it up and it looks to be pretty clean inside. I pulled out the board that looks to have the power supply filtering caps on it, hoping to see something amiss. Visually everything on that board look ok.
I would like to try and fix this, but am going to need some help as my knowledge is limited..
I don't know how to check voltages if it is blowing fuses? If anyone would like to help me or have any suggestions, that would very much be appreciated.
I have the manual and schematics for it.
I figure I should ask you guys before pulling more board out!
