    Pics of my troubled boards #2

    MSI 6340 v1.0:
    M6340 K7TMPro

    This board was awesome! Until it started rebooting and freezing on W2K. Damn! this board was cheap at a local comp. show back in the day of all the eMachines and Systemax warranty returns (I didn't know any better at the time). Anyone remember? There were thousands of returned machines that the white box builders bought at auction and parted out. New shit for cheap, unless you got a MSI or a Giga like me! The PSU in the new cases also had the crap caps and puked after a year of 24/7. Anywho here's the materials list:

    4700uf 6.3V (4) Lelon
    3900uF 10V (2) Yageo
    2700uF 6.3V (1) Tayeh
    1000uF 6.3V (6) Tayeh
    330uF 6.3V (2) Tayeh
    100uF 10V (1) Tayeh

    This board was tested and purchased with caps that were good, but then went bad. Live and learn.

    BTW- I just replaced another PSU this weekend on a white box manufactured in 2000. 250W PSU blew vented all of the low voltage side of caps. New brand for me please add it to the list "SU' scon"

      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
      by ugamazing
      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

      Apple M1 Boards & Exclamatory Error?
      by ugamazing
      We've now created a stack of 10 boards that have the same issue, which we suspect to be CPU-related. The issue is very simple--the board will not boot to anything, only showing the exclamatory sign inside a circle. No amount of DFU/restore, wipe/erase, etc, will resolve the issue. No boards have physical damage. We went ahead and replaced the SSD nands on two boards (one 02020, one 02016) and the issue remained exactly the same. We are considering replacing the CPU on one of the boards using a locked CPU, just so we can see if it resolves the issue.

      Has anyone else run into this...

      Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
      by ugamazing
      I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

      Legion 5 PRO, 3 boards, same problem, NM-D562 Rev. 3.0 motherboard
      by hopkok
      Hi friends, last week I got 3 same boards for repair (NM-D562 Rev. 3.0), same problem, power button light up, but motherboard wont start.

      3,3V_alw and 5V_alw, 1,8V_alw and 0,75V_alw presented on all 3 boards, no other voltages. 1,2V missing and if I checked schematic right, I need 1,2V and than can be +3VS and +5VS generated after getting SUSP_N signal from KBC? or vise versa?

      I checked for low resistance on coils, no low resistance.

      Anyone with same issue like me?

      Thanks for any help.

      Panasonic TC-P65S2 SU or SD Boards Bad?
      by midnightg35x
      I have a TC-P65S2 that blew an SC board (I had a previous post about some cross references). When I put the repaired SC board in, it worked with the SD and SU boards isolated and SC50 jumped. I reinstalled the SD and SU boards. I did forget to remove the SC50 jumper, but from what I understand about how that jumper works, that should not cause SC board destruction with properly working SC/SD/SU boards. When I turned the TV back on, the SC board blew again. Based on the fact the SC board was working without the SU and SD boards, it at least makes sense that one or both of them is bad.
