    vizio E60-E3 backlights, sound, no video
    by ajshoe
    Have a free Vizio E60-E3 pickup - sound and backlights work. set turns on and stays on for a period then cycles off and back on. NO VIDEO. If I remove left side (from front of TV) of TCON cable - set has pic on right side (from front of TV) with white screen on left side. With right side TCON cable disconnected - no pic on either side.
    Does this mean remove right side (from front of TV) tabs ?

    Like a second opinion before possibly destroying set....

    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...

    Audio video receiver KENWood KR-V990D,no sound
    by JRade
    When I select the FM receiver, I find a radio station, the sound is heard on REC OUT(L,R), REC TAPE1(L,R),REC TAPE2(L,R) on high-ohm headphones, the sound regulation does not work.
    The output reacts when I connect the record player to PRE OUT FRONT L, the sound is heard in the speaker but the sound regulation does not work. Then it does not matter what I chose on the front selector.
    I replaced the capacitor C303/0.047F, nothing changes.
    I'm asking for help, what should I do next?
    Thanks in advance!...

    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...

    KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen.
    by mecha1166
    KDL-60EX500. Comes on fine, sound is fine, backlights come on. Blank screen. Already tried reset POWER/VOL-. Anyone else have this problem? Possibly bad T-Con RUNTK4244ZZ or panel? Could main or power supply cause this? There were 2 blown 560u 35v on power going to backlights but they were still working fine. Thanks for your help.
