    Samsung 2233BW is temperamental

    Previous donor told me it turns on "when it feels like it".

    I crack it open and fail to find any popping on the caps. I use ESR Micro 3.1 and make a few readings:

    C105 features a JH CD266 (827604) 100uF/450V testing at 93uF and 0.01 Ohms
    C107 (forgot to take readings)
    C108 features a SamYoung NXB 820uF/25V
    C112 (same as C108)
    C113 features a SamYoung NXE 1000uF/10V
    C116 (same as C133)
    C118 (forgot to take readings)
    C119 features a SamYoung (forgot the series) 330uF/10V
    C301 features a SamYoung LXZ 820uF/25V testing at 3544uF/0.00 Ohms
    C302 (same as C301)

    My current plan of attack is a blanket replacement once I get enough qualifying 820uF capacitors.

    I'd love suggestions for a more focused plan with specific parts. Given the 23" screen, I'd love to get this working.

    Thanks for reading!

    1) What are the DC voltage readings on CN2? Do the readings match the legend?

    2) Get readings for all caps with your ESR meter.

    3) Does the power LED come on?
