    Pulled - $25 Pulled by Coppell themselves.

    I believe the $25 is culled from the working board of a ysus/zsus combo sent in for rebuild. Conventional wisdom says when one fails the other is likely not far behind. Meh. I think i will order one and spend a few dollars more on active cooling for each heatsink.
    What do you think about the NewEgg modules?

    I also have thought of active cooling. There's at least one 2-pin, fan-looking socket thingie on one of the boards, and I know a computer shop that sells miscellaneous used fans out of a bin for about $3.00 each, so I can get anything I want for cheap.

    Also spent an hour yesterday looking to upgrade the thermal pad, as it occurred to me that increasing the size of that pad might increase it's ability to pull heat off that board. The problem I found is that there are almost no vendors of 10mm thick pads. I found one, but I'm reluctant to purchase something blind from some company in China. Rather go with eBay, but could not find any eBay vendors with anything thicker than say 5mm. I also hold-open the possibility that the pad is "bad", given the obviously leaking liquid from it; I wonder if years of high heat has caused the material to degrade and lose it's magical heat-conducting abilities.

    So, a source of thick (10mm) thermal pads is on the wish list.


    EDIT***
    I take back my disgruntled sentiments on Digi-Key's search features in a previous thread.
    Here's what I found so far:

      The Newegg modules would probably be fine (who the hell can keep track of what the chinese are faking anymore...) if you don't mind waiting for the slow boat. I'm still waiting to hear back from Payless before I make my next move.

          Update: the Coppell TV ipm is installed and working. I had a missing 15v line which turned out to be a bad connection but made me think bad module at first but all good now. For how long ? Who knows. No warranty is expressed or implied lol.

            A2442 - No sound over internal speakers and no video playback
            by soeren
            I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).

            All happened after the battery ran out of power overall several days when I was on vacation.

            I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery...

            Onkyo HT-R390 no sound output, video output ok
            by FrancescoV
            Good morning everyone,
            I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

            The firmware reported is the following:
            M:1.00/11107BLP
            D:?.??/????????
            O:1.00/11107AL

            The DSP firmware given the question marks seems corrupt.

            On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...

            Samsung UN55H8000 sound but no backlight no video
            by Max514
            Hi all,

            Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.

            The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.

            I came across this page and followed the different steps: https://techhometravel.com/samsung-u...ight-no-video/
            • Unplugging the main board cable at the power supply >>> backlights came on.
            • BLU_ON signal from the

            Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
            by LEECH666
            Good day ladies and gentleman!

            I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

            This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

            I think the PSU buzzing comes from one of the coils near the bridge rectifier but...
