We had a "power issue" here a few days ago and now our Samsung SyncMaster 931b is not working. The blue power light around the button flashes and every second or so the display will flicker with light and you can briefly (for 200ms or so, I'd guess) see the display.
From what I gather, this is due to a voltage flicker through the transistors in the power supply tricking the monitor into thinking it's being shut down so I take it apart and notice three swollen caps on the power supply board (Samsung IP-35155A, components C113, C112, C316, 470uF 25V, 820uF 25V and 820uF 25V, respectively). I figure those are what are feeding the transistors and they're hosed and it's screwing with the operation of the monitor. A capacitance check of each shows about 16uF. Bad caps; I'll get some more from DigiKey and replace them and hopefully that fixes the flicker problem.
The new issue:
I guess I wasn't paying too much attention when I took it apart so I'm wondering where everything goes. I think C113 is the 470uF and the other two are the 820uF caps, but I'm not sure. Can anyone verify that?
Also, I wasn't paying attention to where the connectors for CN301, CN302, CN0303 and C304 went. They all have the same wire colors, are all the same keying, etc. and they are grouped into sets of two which have heat shrink around them so I can't tell where they go. The picture here shows a simple diagram with the connectors marked with a red box. What are these connectors for and how should they be hooked up? Is it just lamp power? Does it make a difference if CN301 and CN302 are switched and/or CN303 and CN304 are switched?
