    vizio vt240m great picture NO sound

    I have a vt240m board CBPF9D1KZ1. The problem is that I have no sound. Picture is perfect, remote works great. Just no sound. I have tried resetting the eprom, tried resetting all sound features to factory defaults. No luck. I have not torn it down to look at the back of it. Are there any other test that I can try before tearing it down. Wife doesn't really want me to tear it down, but that is where I'm at.

      Do you get sound on the Headphone jack?
      Speakers are turned on in the user setup menu?

        I'm not sure on the amp chip, i haven't opened it up yet.

        I tried the headphone jack, and no sound. and yes the speakers are turned on on the setup menu

          Sorry I typed the title wrong. it is a vt420m TV, not a 240. Is there anyway to change the title?

            Vizio M65-E0 No Picture, No Sound
            by ggil44
            Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...

            Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
            by TR103
            Hi, I have a Samsung UE50TU with:
            - sound and backlight, but no picture
            - when it arrived, it had a picture for a few seconds
            - it keeps rebooting
            - without ribbon cable between the two panel boards, it does not reboot but I have no picture
            - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
            - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

            - without cable between mainboard and lcd panel and with a jumpered...

            Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
            by Mgiffune
            I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

            I ordered a supposedly ‘new' Tcon board this time, and

            Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
            by Ierwin
            Hello everyone,
            Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
            The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
            He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
            I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
            Anyway I still fully expect that there has been something seriously damaged...

            Samsung UN70NU6900F no picture and no sound
            by jchang
            Hi all

            I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



            Symptom:
            No picture no sound.
            When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
            No sound at all.



            What I tried:
            1. I tried unplugging the left or right ribbon...
