    Gateway LP2207 /FPD2275W Bad Caps need help

    Hi,
    I have a Gateway FPD2275W/ It also goes by LP2207.
    It does have 2 bad caps on the inverter board. The 2 caps are 12J 3KV JNC. I was able to find a replacement part(thanks to someone on another forum!) One looks like its ready to burn up and the other one all ready has. Do I need to replace the other cap There are 2 more caps(same kind, that look like there part of the invertor circuit.
    N3
    3KV
    SEC
    Since no one seems to know on this one and it looks fine I was wondering if I can get away with not replacing it. Also Should I replace all the Electrolytes caps. I tested them all with a ESR meter all came out good, but the filter cap. Its a low ESR but a little higher than it should be. .73 and should be around .53. There where a few that had real high Capcitance(instead of 240 or 640 they where like 2400, but Im guessing possible because they where in circuit. My meter will test in circuit but it may still be througing things off. I didn't test any of the ceramic caps. There are a couple of those as well. None of the caps looks bad excpet the 2 bad 12J's

    Thanks in advance!,

    Nico

      Hi,
      I ended up just replacing the 2 bad Ceramic caps and all the other Electrolyte Caps except the Large on o nteh AC side. I wasn't able to find out what the replacement part was for the other ceramic cap. So far so good it's been working well since July. Lord willing those other caps will keep working
      Thanks for the response/ help Greatlly appreciate it

            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."

            Identifying caps on an old Zoom 9000
            by Paxman_Swede
            Hello!

            I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

            The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

            I have studied the board and...

            HannStar Hanns-G HC194d LCD monitor repair
            by momaka
            Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

            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?...
