    OST = I.q?

    I found these caps on the input of a K7S5A rev3.1 board:



    The flip side shows these are OST RLP series capacitors. OST is often bad, but not nearly as bad as IQ. For some reason I can't fathom, they've revealed on this label that I.Q is an OST product!

    My guess is they improved their caps (somewhat) and changed their name to OST at that point.

    Search for: QSC K10.2 Circuit Diagram & Component Layout Overview
    by klebendes_etwas
    Hello everyone! :-)

    An acquaintance of mine works as a DJ in his spare time and brought me a defective QSC active loudspeaker (Model: K10.2) for repair.

    Error description: The device could not be switched on (after he lent it to another DJ).

    A visual inspection revealed an obviously blown fuse (F41) and a cracked thermistor (R41) on the mains filter board. A closer look at the amplifier board revealed two defective power MOSFETS (Q13, Q14) and other defective components on the +12VLOW rail.
    After replacing all the obviously defective components, the...

    ThinkPad E14 Gen 4 AMD NM-E501 dead
    by rumpumpel1
    I have an E14 Gen 4 AMD that shows no signs of life.
    When connected to the charger the board initially drew 30 mA at 10 V.
    The thermocamera showed a hot spot at one edge of the PD controller. I therefore replaced the PD controller, after which the board drew 5 mA at 20 V.
    Further investigation revealed that the power switch UT5 (NX20P5090UK) was not activated. The EN# signal is missing. This is supposed to be generated by the PD controller.

    From then on I started using the battery instead of the charger.
    With the battery the main power rail V9B+ is present...

    TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
    by howardc64
    All left and right refers to looking from rear of TV (or looking from front with TV upside down)
    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

    Sony M851 MBX-217 no POST and restart loop
    by davidebeatrici
    Before proceeding with a component level repair, the usual troubleshooting process was followed:

    1. Disassemble and unplug everything except the power connector.
    2. Replace RAM.
    3. Replace CPU.
    4. Rewrite BIOS.

    Unfortunately the board was still stuck with a 0.75A power consumption at 19V.

    After reflowing both GPU and north bridge in one shot (it can't hurt) there was an instant improvement with a constant 1.75A power consumption, but I immediately noticed smoke and the typical smell coming from the GPU area.
    I thought to myself "Well,...
