    Beyonwiz FV-L1 (and certain others) - bad Samyoung NXB

    Upon opening a Beyonwiz FV-L1 PVR, I found the following bad Samyoung NXB units:

    C14 (3300uF 10V) - on switched +3.3V rail before output inductor and MOSFET switch
    C15 (1000uF 10V) - on switched +3.3V rail after output inductor and before MOSFET switch
    C17 (2200uF 10V) - on unswitched +5V rail

    Replacing all of them (along with the other Samyoung NXB units) fixed this problem.
    In some PVR units, the electrolytics are literally being baked, such as in the Topfield TF5000PVR(T/C).

    Should we add Samyoung NXB (as well as Samyoung NXA) series to the bad caps list?
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      Lowest possible resistance on laptop motherboard rail - Guide Table request
      by Nagy Daniel
      Hi, I'm Daniel, and I'm new to the world of repairing motherboards.

      I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.

      I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.

      So, I generated a table with AI so I can...

      Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
      by Victor Moreira Silva
      Hello everyone,

      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

      Well, my decice specs are the following:

      Model: Acer Nitro 5 AN517-54-55T5
      CPU: Intel Core i5-11400H
      GPU: NVIDIA GeForce GTX 1650
      Motherboard: GH51G LA-L181P Rev:1c

      The symptom:
      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...

      Lenovo Thinkcentre tiny M90Q gen 1 - no 12V rail
      by lefetylorant
      Hello Everyone,

      Long story short, I got this unit for very cheap.
      I've started to experiment with it's BIOS, as I did before successfully with an M900. However my very bad quality SOIC clip broken while dumping of the biosof and it must have damaged something on the panel, because it does not turn on, and does exactly nothing when powered. The maximum voltage that could have affected something is the 3.3 or 5v from the IC clip, because the unit was not powered while the bios dumping was in progress.

      I've performed some measurements:
      - 20V rail perfectly...

      Weird behavior on 3.3V rail of a CORSAIR CX600
      by bimole
      Hi,

      A colleague gave me an apparently ill CORSAIR CX600.
      He told me that he heard a banging noise, and smelt the magic smoke.
      After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.

      I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
      It's another story on the 3.3V rail...

      I have some devices to test deeply PSUs (scope, AC source, electronic load)...

      Acer TravelMate P214 - N19Q7 main power rail shorted to ground
      by mkdj
      Dear all,

      I have taken out the motherboard of a Acer TravelMate P214. There is a short to ground on the main power rail (19V). I don't have the schematics or boardview for this board (DAZ8IMB1AA0 REVA). But I have found 4 MOSFETS close to the main power rail : 2 N-Channel and 2 P-Channel.

      I have checked resistance across each of the 4 MOSFETS. I have the following readings:
      Both N-Channel Mosfets: nothing odd

      P-Channel MOSFET number 1:
      source - drain : 117 kOhm
      source - gate: 96 Ohm
      gate - drain: 117 kOhm

      P-Channel MOSFET...
