    Sony PCG-71211M [no SUS_ON signal]

    Hi

    Motherboard:
    M961_MP_MB MBX-224 [1P-0106j01-8011]

    Laptop doesn't start. There is 3.3V on power switch. It reacts on that switch, turns on, but it only gets like 50mA of power. +5ALW is Present, +3ALW is present. No 3V on BIOS memory chip. There is no signal SUS_ON on Super IO.

    Resistance to GND on all coils normal (kOhms and Mohms).

      Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
      by AstutePauciloquent
      Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

      I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

      by howardc64
      Failure Symptom



      No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

      Where is the short?

      Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
