    Shuttle MS51 Bad Caps?

    Looking at a friends PC failed to POST and wont display anything. I assumed it was the Power Supply, but swapped out with a spare but no go.
    Noticed some brown stuff on the top of a G-Luxon cap next to the RAM slot which led me to this site.

    The G-Luxon caps next to the CPU are all bulged also. One of the large G-Luxon capacitors next to the VGA out connector is bulged and raised higher than its sister cap.

    I am assuming BAD CAPS but searched on MS51 and cannot find any other boards reported. Any other ideas on failure to POST prob?

    Thanks in Advance

      I'd just go with G-Luxon as the culprit, I've seen 3 mainboards on my desk, all non functional, all with G-Luxon... Junk.
      Ya'll think us folk from the country's real funny-like, dontcha?

          Sure it's not an FS51??? That's the motherboard that comes in an SS51G. I've got one that suffered partially melted +3.3V wires in the ATX connector. Looks like it had a loose connection, and it was just arcing all the time. Caps look good on it though. What brand of caps does your board have??

              Thanks for the replie(s). gg1978 I am sure that it is a Shuttle MS51 board (refer pictured link below). There is no shuttle name on the board but MS51 is clearlyly printed and the board matches the picture. I had the ATX connector off when trying a temporary power supply hook-up. No evidence of any prob there and it still would not POST. I can confirm that the leaking one (plus other bulged ones) is a G Luxon (thus I found this website when I googled it up). The 6 bulged ones next to the CPU socket are mainly black (and plenty dusted!) and had RLX printed. I think these are OST manfacture? The remainder sprinkled elsewhere seem OK being still flat on top.

              I will assume that because I searched this site for MS51 without a hit that I am the first to report a dose of BADCAPS for this mobo model/manufacturer.

                  Well, it appears that your friend's MS51 and my FS51 are about the same board, the difference is that the MS51 is microATX, while the FS51 is the really small custom form factor for shuttle XPC's.. I knew that shuttle made regular mainboards, but they're known more for their little Shuttle XPC's.. Sure does sound like you have bad caps though.

                      Heathkit IO-4205 Power Supply Caps
                      by eryjus
                      Hello,

                      First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                      I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                      I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                      ...

                      Help with switching power supply caps
                      by captain150
                      I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                      I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                      Gigabyte GA-6OXT :: caps question
                      by Foetuss
                      Good evening

                      I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                      Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                      But I was also suprised about the bigger boys, which are 330µF 25V.
                      Could it be they used 25V caps because they were cheaper / available at that time?...

                      EVGA e-GeForce 7600 GS AGP 256MD2 [256-A8-N542-T2] with bad caps - fixed
                      by momaka
                      I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)

                      So, here is the...

                      Replacement caps for Samson Resolv studio monitor 65A Amp board.
                      by black6host
                      Good day!

                      I have a Samson Resolv studio monitor that has no sound output. I've opened it up and found two caps that are bulging on what I believe to be the power supply section of the amplifier board. The board is marked Resolv 65A AMP V1.2. The caps in question are YUSCON, 2200uF, 35V, 85C temp and have markings of RA(P) and are 16mm x 25.5mm tall. I've attached the schematic and the caps in question are C5 and C6. I'm assuming they are low esr caps. I've tested both caps and they test low uF, nowhere near 2200uF.

                      I'm going to replace the caps and I'll be the first...
