    MBP 820-00928a need advice

    I'm working on an a1707 macbook pro for a friend of mine that said it had stopped working and will not turn back on. After opening up the laptop I discovered a short on C7382 which took the PPBUS_HS_CPU to gorund.
    After fixing the cap issue, I had 12.6 volts on the line. Not sure what or when something happened, but I am now getting 3.6 to 3.8 volts fluctuating. I was taking some volt readings and I'm not sure if I shorted something or if something else has happened.
    At this point, I'm not sure where to start looking for something to fix. Maybe the cpu fried anyway when the PPBUS_HS_CPU line shorted.
    Looking for some advice on where to start looking for issues. Any help is appreciated.​

      CH341 programmer advice, including jumpers seemingly reversed
      by chazzo
      I’d appreciate some very basic advice on CH341x programmers. I know this topic comes up from time to time, but stuff changes, so I hope a refresh is in order. In particular, I see some unexpected things happening with jumper positions.

      [My plan is to learn to read and write 24CO2 EEPROMs via I2C. The first target is the one in my Uni-T clamp meter, but before tackling that I have some brand-new EEPROMs to practice on.]

      I have two basic Chinese programmers. One is the blue board with a CH341A and two rows of pin headers. To my untrained eye it looks like all the others....

      Need T-Con Advice (Vizio P602ui-B3)
      by Jidis
      Hi all,

      I made a big-ass mess here of my father's beloved P602, and I'm trying to figure out if I should order a batch of overpriced ribbons or if I'd just be throwing more good money at the bad.

      He woke up recently to a bunch of white bars going down the right side of the screen. From what I'd seen in these places, I figured the T-con board has gone out or has a bad connection. I took the back off and gently poked at the socketed ribbons and sure enough, got the image back. It was mainly the far left ribbon, and it would snap back to stripes if I let off the pressure....

      Seeking Advice: Repairing Dell U3425WE Monitor with Faulty USB-C/Thunderbolt Ports
      by Borse2008
      Hi everyone,

      Looking for some advice or opinions on what to do with a monitor issue I’ve run into. Apologies in advance is this crossovers a few forum categories.

      I have a Dell U3425WE, which I've recently replaced with another model. That said, the original unit is still fully functional in terms of the display — it works perfectly over HDMI and DisplayPort. However, the USB-C and Thunderbolt 4 ports have stopped functioning correctly. The Issue:
      • The 90W Thunderbolt 4 port (circled in the photo) no longer charges or powers any device, including laptops or MacBooks.

      Mosfet Advice
      by Green Probe
      Hi, Im looking to replace some EMP21N03 mosfets on an Alienware motherboard, but I'm having trouble finding a legit supplier. The ones that are available from China have pictures with the engraved logo looking very scratchy and sketchy. Nobody in the US sells them. I'm trying to find a compatible mosfet, but I'm not well versed enough to be confident im making the right choice. Does anyone have a suggestion or advice that could help me find the right mosfet? Thanks!
