RE: U2412M, Repair a defective diode
Thank you for your post, very helpful.
I think I have the same problem with my U2412M, just lost power all of a sudden with no warning or flicker just went black.
Not being very electronically minded I think I have identified the diodes on the power board and putting the multi meter on them reveals that 2 of them (D702 and D703) don't work (well the meter doesn't buzz!). The other 2 (704 and 705) do seem to work.
The two diodes "seem" to be the same, would that be a very bad assumption? Or could I get two of the UF5408's and just see what happens?
Hoping to get this monitor going again as it is only 4 years old.
Thank you for your help
