      Woaahhhh hang on everybody!!

      Skyking was the one with the obviously bad MOSFETs, not johnnyblazing. The FETs on johnnyblazing's board are probably all fine, and don't need replacing. His board just had bad caps. I think that what confused us is that he started post 14 by saying "Update", so we all thought he was the OP.

      I love putting bad caps and flat batteries in fire and watching them explode!!

      No wonder it doesn't work! You installed the jumper wires backwards

          Bingo!

They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

            Thanks for the clarity on that guys, I didn't see any other physical damage except for the 2 bad caps. I did take the advice of an earlier post, which was to replace them all (Caps), which is what I'm doing this weekend. Again I thank all of you in this forum for the wonderful advice and resources.

              Hi,

              This is the only one "XPS 710" dedicated thread I, so I decide to post here instead of creating a new one.

              I get an XPS 710 H2C but I notice some bad caps (however it works)

              I know it's old and bulky but I love the design and want to run old games on it.

              There is 3 green caps that I can't identify. Could you help ?



              There are located here :



              There is a line of 4 caps, all are identical but a black one showing 820uF 6.3v 105°C.

              The 3 green one are just showing S.E. 69 105°C WF

              Any idea of the green caps spec ?

                Those are Sanyo caps, the values should be on them.

                  Thanks for the manufacturer information.

                  However, except what is visible on the pic (SE69 WF 105°C), there is no other handful information.

                    Look on the other side, it has to be there....but if I had to render a guess, I'd say they are one of the following: 1000uF 16v, 2200uF 6.3v, or maybe 1500uF~1800uF 6.3v. They are 10mm in diameter, and appear to be 16~20mm tall.
