    PSP Go - No backlight - fuse shorted (keeps shorting)

    Hello all,

    I have a PSP Go that is working perfectly on TV but nothing is displaying on internal display.

    Screen is new, cable screen also.

    I did jump the fuse (see pictures) with no luck.

    When measuring on both side I get 1.29v on left side and 3.74v on right side. I do think that the 3.74v is fine but not the 1.29v. I've done some measuring around and found 2 caps that are shorting to ground (low impedance, but should be fine with readings 28.9ohms) but have no clue of where they are going.

    I'm thinking that the 44c019 chip is maybe faulty?

    If somebody has an idea, it would be really helpful ! Thanks !

      ok, solved, problem was that fuse was in a bad state and made a connection to the component next to it. Removed and placed a new one solved finally the problem. Thanks !

          Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!
          by reessi
          Hello:

          I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


          I started on the ACER:

          Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
          All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

          I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

          A funny fuse story – Lumix LX100 II
          by corrize
          Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
          I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
          The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
          There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
          And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping...

          Panasonic TC-P50S1 shorted TXNSC1EDUU (TNPA4782AB) SC Board
          by Yanleb
          Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

          I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

          D608, good
          D618 RF101L4S, good (See warning 1 below)
          D619 RF101L4S, good (See warning 1 below)
          D865 RF101L4S, shorted (See warning 1 below)

          HP Victus 15-FA1025NL , board DAG3PAMB8D0 REV:D, shorted CPU DrMOS and n-mos
          by modtool
          Hi to all,
          the owner of this machine gave it to me after having opened it to take off the dust from the inside, telling me that after that it didn't start anymore.
          I found that one of the DrMOS (AOZ5016QI) on the CPUCORE was shorted between VIN and VSWH, and that one of the two n-mos connected to the power jack was shorted aswell.
          I unsoldered the two shorted components and verified that there were no other short circuits, then decided to power the mainboard, firstly with the lab power supply, then with its original HP 200w charger, but the behaviour is the same, the board starts...

          Apple 820-3662 VCore shorted to ground.
          by barry101
          Hi, Would appreciate some help.
          I have an Apple Late 2013 15" A1398 MacBook Pro with Logic Board 820-3662.
          Get charger light but no fan spin or chime. No liquid damage.
          Found PPBUS and VCORE both shorted to ground. Other rails were ok.
          Removed VCORE MOSFETS U7310, U7320 and U7330. Found U7330 was in fact shorted.
          With the 3 MOSFETS removed, get PPBUS and fan spin. VCORE is still hard shorted to ground (0 ohms).
          Attempted voltage insertion on VCORE to locate short using bench supply set at 1.0 VDC and 4.95 Amps (max current for my...
