    Running out of Ideas, hoping someone smart can provide some for my ONKYO TX-SR353 Receiver
    by CDNBrewer
    Hello Everyone,

    I have an Onkyo TX-SR353 Audio/Video Receiver (5.1 ch with HDMI) that I am having a really hard time diagnosing and I'm about to throw this in the junk and go buy a new unit that is on sale until the 7th.

    Symptoms:
    • Intermittent (part of the reason why i'm having a hard time isolating problem), sometimes will work for 10+h at a time without issue
    • Original symptom was wife reported loud banging noise (like someone was banging on the wall with their fists) from the LEFT SURROUND speaker and then the unit shut off.
    • I swapped the Left and Right surround

    3090 FE Part Confirm/Identification
    by H H
    Hello,

    I'm hoping someone could help me confirm if I have identified the following parts correctly.

    Apparently the DP cable became stuck inside the graphics card and was yanked out. This caused some sort of short which burned the DP contacts and blew some resistors and ferrite beads.

    The parts needing replacement are on the back of the board behind the HDMI input.

    I have identified the parts as the following:

    C6037: MLCC 0.1uf/16v(0402)x7R W05

    R6016: RES 499 OHM 1/16W (0402) 1%

    LB10911: Ferrite Bead (0402)...

    Nvidia Tesla P40 (Q0V80A) Enterprise GPU, I put the power cable on backwards.
    by olliec420
    Ok I screwed up big time and hoping I can fix. I will break down what happened and the images.
    • Have Dell PowerEdge R730
    • Bought Tesla P40
    • Researched power cables and order correct one, pic had two black connectors in photos
    • Power cable arrived, same connectors (EPS-12v) on both ends
      Both sides are the same plug but different colors. The listing stated that colors would be random. OK I plug it in, red side to riser board, black side to GPU.
    • Power on.
    • System immediately turns off.
    • I only had 1 PSU plugged in and it was blinking orange, I thought I drew too much so I plugged in
