RE: U2412M, Repair a defective diode

Hello cryptos10.

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
