Re: Samsung SyncMaster 2493HM black screen with power
Update: lcdalternatives shipped the missing cap and has fixed their kit to correctly match the board.
I installed the 2 caps on the inverter board and now the backlight doesn't turn on at all. I didn't really know what I was doing on the surface mounted components, so maybe I didn't get a good connection? I removed them, cleaned off the contacts with rubbing alcohol and resoldered. I also melted the solder around the big black components with the wire wrapped inside, thinking that might help. All the solder looked dull, not shiny like on the power board and the new solder, but it looks the same after re-melting with a little black and yellowing around the board where it contacts.
Anyone have another suggestion? I have ordered a new monitor but I kind of like tinkering with it/soldering, although I'm not very good at it.
Thanks
