    in General Electronics Technical Discussion
    Re: Mismatched caps?

    HI Gang

    By visually looking at the joints you can get an idea BUT they can look good and be bad
    since its a know problem with these Boards
    Then Id rework the solder joints

    Normally this would be done by removing the solder with "de-solder wick" or a "solder sucker" hobbyist way since its cheap (not that pro's dont use it)
    professionally with a de-solder station and then re-soldering them

    I am not sure of your level of skills but if you haven't really soldered or used wick...

    Re: Why do fluorescent Bulbs (CFL) last only a few months?

    Hi All
    well didnt read it all but yep why don't they last as long as they are suppose to or so short a time..probably cause they are made of junk as was pointed out,
    dont like a lot of switching too...
    I have a stuffed one that I know was used for years (like 10 or possibly more) in a work kitchen but that was like $25 AU at the time it was bought... when they were a new thing

    on the green question well again here they banned the old faithful incandescent so we are forced to use them,...

    Re: Diode Test

    I hate DMM's
    it should read open circuit one direct (Very high resistance)
    near short the other
    (actually I think your reading a voltage drop across it or something..forgotten now on resistance ranges..but dont quote me on that)

    Diodes mostly Fail completely
    but sure there are cases of some aspect cause problems in circuit

    Type is High speed rectifier its still a diode PDF

    Here the pdf on the STM9435 Appears to be a FET

    Sound like that might be your problem
    but wait...

    Re: Pls, help me for Ambit T501045.00

    well dont know about those inverters but the transformers have been known to go.

    I do remember a discussion (don't think it on these forums) about this
    it was advise to put new ones in as well...(like if you can find them)
    (in one model inverter)

    If fuses are popping then it obviously too much current being drawn this means a fault is still there ..the question is why
    and no I DO NOT recommend what you are suggesting.

    Yeah same here up goes the price...and even more so since Rudd signed that agreement on trading carbon emissions (whatever)
    I think the US still hasn't

    OK Rant over

    Regardless I think the question is a very valid one

    OK can turning things off save power etc, well I suppose it depend on how much is being used really and how much...

    Re: Other than a soldering iron and meter, what should / could I buy?

    Hi Fizzy
    well dont take this the wrong way mate
    but Knowledge my friend
    A good sound understanding of the basics of electronics can take you further then any Rolls Royce of Oscilloscopes

    Knowing how to use them and what they are telling you

    So get studying
    plenty of sites out there to learn from and brains to pick here

    On tools, me well a good meter(or 3) an ESR meter and of course a decent Soldering Station (desolder stuff too is...

    Re: Melted fluorescent light....

    well not familiar with those things but obviously this is something that should not happen...mostly now whatever standards are suppose to be in place they are not followed like they use to be...basically any junk can come into the country.

    the El-cheapo Tube may have been the fault I don't know.

    but if it follows normal fluro's for 230VAC
    you got a starter, ballast (inductor) heaters in the tube (ideally a PFC Cap)

    what happens the starter fails and the tube heaters just sit there burning up...this...

    Re: Linksys BEFSR41 Router Capacitor Solution

    yeah I dont think they have a great rep...mine has been fine so far

    They do have crap caps and heat I think is another issue for them...just cause they are owned by a "real" Router Company doesn't mean linky's are...so I guess price is a factor really you get what you pay for but then again you can pay a high price for crap too.

    all my router stuff is linksys for me at home, I have no real complaints but then I have to say they dont get a real work out either
    worse I found is the wireless...

    but that could be a shot Bridge rectifier.

    You need to check/replace it or firstly if you got a meter check the voltages.

    in Troubleshooting TVs and Video Sources
    Re: Monitor worth saving?

    Generally speaking
    For the price of some decent caps its worth fixing.
    mostly caps are the issue, although inverter transformers have been known to pack it in. (also other faults have been known depending on brand model)

    Be careful as that has High Voltage on that PCB and also directly connects to your Mains supply system

    Make sure you put the caps in the right way round too.

    As willa said looks like (unfortunately) fairly normal cooking of PCB.

    there can be other issues of course...

    Re: Start up kit.

    Read willawake FAQ on recapping its not that hard to do

    [url]https://www.badcaps.net/forum/showthread.php?t=485[/url]

    you will find mostly MB around the 2000 ~2003 maybe 4 period
    are liable to have bad caps
    newer systems with Electrolytics, sure its possible too just a little less likely
    as some manufactures woke up and the bad formula jobs were gone (hopefully)

    but depending on age and abuse other too
    (most stuff older has probably been dumped)
    but there could be a few older systems...

    Re: Gigabyte GA-8IDX and GSC caps....

    Well there is an old saying if it ain't broke don't fix it
    since I guess its been working for awhile and its one of your systems I wouldn't bother stevo
    you been around here long enough to know whats going to happen eventually but Sanyos seem to last ok...

    The ideal is no you shouldn't re use used caps and I wouldn't if I was doing a system for someone else.

    I think its probably more mechanical stress issues really we are talking here.
    but yeah less stress heat wise and unknown hours of use...

    Re: Gigabit 7VAXP

    good point gdement.

    I did something similar,
    I think the MB may have come in both flavors too, some had all 9 later ones didn't
    (think the 9 were GSC crap)

    but dont know for sure just photos I've seen on the net

    here mine

    [url]https://www.badcaps.net/forum/showthread.php?t=3828[/url]

    I wouldn't stray too far from nominal capacitance really, but I add about 6000 uf
    it will work.

    my case 13,200uf Sanyo's.(4 off)..these VRM output,
    KZE are VRM input...

    Re: Capacitor

    the others really deserve the thanks they are more clued up on it them me.

    not sure on the noise, motors I don't think like running slow, maybe the repairs just pushes a little too slow if you get what I mean

    but no expert here.

    I probably just not run it at slowest run it were it sounds right

    but the other would I guess have more constructive input.

    Good one thought glad to hear!

    Re: Gigabit 7VAXP

    if they are GSC then its odds on they are history thats for sure
    althought you already stated they are stuffed

    sounds like typical stuff caps symptoms to me.

    chances are if its still freezing but booting a recap will fix it.

    Just make sure you use quality low ESR types if you want it to last for a long time

    read the FAQ's and posts for tips and tricks
    on cap replacement if you need to ...sound like you don't but it cant hurt anyway.

    good luck

    cheers and welcome...

    Re: Quick question

    Whats the MB? what are the symptoms?

    if you read posts around here yes. (mostly)

    you will probably find 6V3 caps can be used
    you must if you want long life out of them use quality low ESR types
    (which is "not" the stuff you normally find at hobby electronics store)

    it better to go a little up then down normally.

    Re: Nova capacitors???

    good stuff mate
    pity about the other MB but it still may be salvageable if you can nail why it failed

    yeah I just keep an eye on the caps if you are going to keep it, you should get a year or more if they are half decent
    even the crap half baked GSC see a year or 2

    just if you are intending on recapping try and get some decent caps so you know it will last for a few years...although this stuff is no getting long in the tooth.
    but there are some apps its well suited for regardless of the age of the stuff....

    Re: Capacitor



    wouldn't the below be a 1 nF 100 pf ?

    If you using a capacitance range on a multimeter the only reason that comes to mind is stray capacitance.

    Does it have a pre zeroing thing?

    guessing from the picture, if it was for EMI
    (as Gonzo said and I agree)
    wouldn't it go to ground the other end ?


    Well I don't know on all 3 counts, so consider these more questions then answers
