RE: U2412M, Repair a defective diode
I'm glad you found my post. Unfortunately, I haven't taken any photos of the repair so I don't remember the diode names but D702 and D703 sounds right!
How have you measured the diodes? Has your multimeter a diode mode?
I do remember that there were two diodes next to each other and in my case one of them was faulty. The two were definitely from the same type. I know sometimes its hard to read but there should be a name printed on the diode. If you can read it, what is printed on the diodes?
If you have a smartphone/camera it would be awesome if you could take a picture and post it here!
