    acer 4750G JE40 dead unit

    This unit is totally dead. No 3.3v and 5vdc output at PU4103, no switch voltage, no supply at bios chip... this unit got a nvidia video chipset.. BTW, i already replaced PU4103 from a working unit with same result. And the original PU4103 being placed to other unit and it works... input voltage (19vdc)at pu4103 is ok..

    Any info where should i begin?

    Thanks

              How can I be sure that my EC chip is dead?
              by double_DD
              Hi all,

              As the title suggests, how can I be sure that my EC chip is really dead?

              I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

              Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

              Repair of an LG split AC system indoor unit PCB
              by ngml
              I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
              This indicates an error in the communication between the outdoor and the indoor unit.
              The outdoor unit is fine, so the problem is the indoor PCB.
              The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
              I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.

              Does anybody have the schematics of this board,...

              Bose Companion 5 - Unit Powers On then Cuts Off Shortly After
              by nobbnobb1
              Hi guys,

              Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.

              When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...
