Hi guys, i'm having trouble repairing a PS4 fat ADP 240AR power supply.

Checking I found several problems (the components that I changed I put it with red color) in the 5v sector and a burnt power resistor which did not allow the activation of the 12v.

Once fixed, the power supply extends the 5v and 12 (when bridging standby and 5v) but when testing it on the console it turns on with blue light and then turns off (if I try to turn it on again the console does not turn on until I leave it disconnected for a while) I think they call these symptoms BLOOD. I used a 600w atx source and tested the ps4, it works fine, apparently the problem is in the original power source

I checked and I think the problem lies with some smd component. What would be the next step to follow? I dont have oscilloscope.

Thanks to a fellow on the forum, I can use a schematic and a photo of the tracks on the board. Which makes it easier for me to know where each signal is going, the thing is that I don't know how to continue.

I am going to post the modified schematic where I have some annotations

    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".
  • Veho @ Veho:
    It's a DS Lite in a slightly bigger DS Lite shell.

    It's not a Nintendo / iQue official product, it's a 3rd party custom.

    Nothing special about it other than it's more comfortable than the Lite
    for people with beefy hands.

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme
  • The Real Jdbye @ The Real Jdbye:
    but that's a long shot
  • The Real Jdbye @ The Real Jdbye:
    i think only the red mario kart edition phat was v5

    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've also never been fucked before." So the man picks her up, and throws her in the ocean and says "Now you're fucked."

    anyways, we need to re-normalize physical media

    if i didn't want my games to be permanent, then i'd rent them

  • BigOnYa @ BigOnYa:
    Agreed, that why I try to buy all my games on disc, Xbox anyways. Switch games (which I pirate tbh) don't matter much, I stay offline 24/7 anyways.
  • AncientBoi @ AncientBoi:
    I don't pirate them, I Use Them :mellow:. Like I do @BigOnYa 's couch :tpi::evil::rofl2:

    @BakerMan - you can still "own" digital media, arguably easier and better than physical since you can make copies and backups, as much as you like.

    The issue is DRM
  • cearp @ cearp:
    You can buy drm free games / music / ebooks, and if you keep backups of your data (like documents and family photos etc), then you shouldn't lose the game. but with a disk, your toddler could put it in the toaster and there goes your $60

    :rofl2:
  • cearp @ cearp:
    still, I agree physical media is nice to have. just pointing out the issue is drm
  • rqkaiju2 @ rqkaiju2:
    i like physical media because it actually feels like you own it. thats why i plan on burning music to cds
