    On M-Audio AV40 active studio speaker's two zener diodes get really hot.
    by Dvsr
    Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
    I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
    After replacing the caps I started testing out the speaker. It seemed...

    GTX 980TI with 2 broken pads on memory module
    by foshland
    Hi, I got a 980TI with 2 pads broken under a memory module and yes, they are needed pads, so I just cant ignore them. Ill try to fix them but im waiting for the pads and solder mask to arrive.

    Thinking on the worst scenario, is there a way to modify the bios to ignore that module and end with a 5.5 Gb card???? (or 5, or 4, doesnt matter, just dont want to throw it away) Its the 12 of 12 modules, so its the last one. Searched on internet without success.


    Thanks a lot

    Certain DisplayPort-HDMI cables can disable HDMI CEC communication
    by japlytic
    With a setup including a TV and AV receiver where HDMI Consumer Electronics Control (CEC) and Audio Return Channel (ARC) functions were working, these two functions stopped working after changing some connections (not the one between the AV receiver and TV), so I believed it was a corrupt setting in the AV receiver or TV, but when I disconnected a passive DisplayPort-HDMI cable (which a Multimode DisplayPort connector supports HDMI with a low cost passive cable or adaptor) connected to a home theatre PC, HDMI CEC and ARC functionality was restored.
    An examination of the HDMI CEC wiring...

    Toshiba 50UL2063DB randomly rebooting with HDMI-CEC and/or HDMI-ARC enabled
    by spleenharvester
    I have this TV hooked up to only an AppleTV 4K and a Creative soundbar. Originally HDMI-CEC and HDMI-ARC wouldn't work at all, I replaced all the HDMI cables with decent UGREEN cables meeting the latest standards, now it all works perfectly but once or twice a day the TV itself reboots while watching a program, the AppleTV keeps running. I haven't fully pinned down whether it is ARC or CEC causing it yet. All are running latest firmware.

    I assume it is just HDMI-CEC being buggy as usual on a shitty Vestel machine, but can anyone think of anything I can try before disabling it?
