    Dell 1905FP Capaitor Layout

    I just recently replaced 3 capacitors on the power supply board on my Dell 1905FP and it seemed to be working okay, being a neebie I read that all capacitors should be replaced just to be safe. So I changed out all the caps and now it will not turn on at all. I have checked all caps to make sure they have correct polarity. Can anybody give me a list or picture of all the cap values and locations so I can make sure I haven't mixed anything up. Thanks

    1) Double check all your internal connections.

    2) Does the power LED come on?

    3) If you have a multimeter, check to see if the secondary DC voltages are present between the power board and logic board. At least one of them should be 5V DC.

        I have looked through the forum and still not found a layout. Could anyone provide a list of each capacitor location and value. i.e.: c102 22uf . thanks

          3 caps on the +5volts are 1000uf @ 16v and there is a 4.7uf on the +5 volts supply too

          4 caps on the +24volts are 470uf @ 35v

          1 cap that feed the +12 external power jack is 1000uf @ 25v

          the two caps near the inverter transformers are 220uf @ 50v

          hope this help
