  • HIS 4890 blown MOSFET and driver

    So one of my friends took a little too long in cleaning out his computer so some dust bunnies did this

    to his HIS 4890 video card.

    Is it worth fixing? It looks like these are the only things that were damaged but is it possible that this blowout caused damage to anything else? Here's a [URL="https://www.dropbox.com/sh/yjxvf4wznavcgj9/mS5oDrNwcH"]link[/URL] to some more pictures of it.

    If it's worth fixing any reputable vendors for the mosfet and driver in NA? The Mosfet is a ME60N03A and the driver a RT9619A.

    Thanks for reading!So one...

  • Re: 17" Imac G5 replaced caps, still won't turn on :c

    SO maybe I posted prematurely haha. I checked the voltages on the supply and oops they were all terrible. Only one 5V worked and the 24V read as 20.9V but everything else gave me a nice 0V. So I modified a ATX PSU to work with it and now both boards work! Although one of them has some graphics problems so I'm going to have to reflow it but other wise success!
    I also managed to get the other PSU from the previous owner, which does the exact same thing as the other PSU. So now I have two I have to fix :p

  • 17" Imac G5 replaced caps, still won't turn on :c

    So I've got two 2004 Imac G5's that I've replaced the bad caps on, but they both still don't work. I bought the kit on here for one of them and the other one I ordered all Nichicon caps from digikey for. Whenever I try to turn either of them on nothing happens, I get LED 1 but nothing else.

    Unfortunately I only have one PSU between the two so that possibly could be it but the caps look ok and I figured the second LED would flash if it was a PSU problem. But just in case I'm going to look up the pin-out and try and test it, maybe even make an ATX adapter so I can use a power supply...

    Yeah my friend bought it from Goodwill, so who knows who had it before and the inductor was like that so I wasn't sure about what happened but yeah looks like whoever tried to fix it got a bit too close Thanks! I'll check those out ASAP which might be awhile since I'm flying down to Cali....

    So I have this same monitor it displays the ACER logo when you turn it on then goes black, and the LED stays green when there is an input, amber when there isn't. I was checking out the inverter board and looks like I need to replace the 10 usual caps, but it also looks like I need to replace one of the plastic blue ones and I have no idea what to replace it with. Here are a couple of pics of my inverter board...
