    Thanks guys for those suggestions.

    I did check the resistance across the buttons when they were pressed/not pressed. They all seemed to be working fine. When pressed they were like 0.2 ohms and 1mega ohms when not pressed. I see what Lotas posted above in post #16. I can look at those again.

    The "AutoVolume" is set to OFF in the settings.

    I have attached a pic of the board below. Yes, it appears to be similar to the one Lotas posted in post #9 above.

    I have tried to do an update, but it says I am up-to-date. I watched the YT video on the key sequence for the factory reset (vol down+Input). Will give that a shot tomorrow.

      I replaced the main board with one from ShopJimmy. Same problem. I have the key controller board coming. Should be here this week.

            I did disconnect the key controller and tested the buttons. Are you saying to disconnect the board and try to turn the TV on? I don't see how that would be possible with the board disconnected.

              Oh right, Vizio goes to power buttons then goes to remote light. Other tvs aren't that way whoops.

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Assuming...

                vizio e650i-a2 (LWJAOZBP Serial) led backlight flashes then turns off, has video (via flashlight) and audio.

                Sony HCD-HX80R Amplifier Volume Control Problem
                by crackedprint
                I have a strange fault on a Sony amplifier. The volume control varies the display from MIN, then 1 up to 30 and then MAX as expected. At MIN there is no sound. However, at 1 it is quite loud and increasing above 1 does not change the sound level.

                I have tried a Cold Reset as per the service manual.

                I have looked at the I2C clock and data to volume control chip IC501 (BD3499FV). Data is only sent to IC501 when the volume is set to MIN or 1. At any other setting no data is sent to IC501.

                I have looked all the way through the service manual and tried many online...

                Marantz SR5007 popping on volume change and mute in Direct Mode
                by BigOof
                Hi,

                I bought a used Marantz SR5007 and it's giving me some issues that I can't seem to really place. It functions well in most settings, ARC mostly works, it has no issues driving my speakers in any of the digital input modes, but I'm having issues running analog inputs in direct or pure direct mode. For some reason in this mode there's distortion for every volume increment I give it, but once the volume is stable it has no issues. Muting creates a loud pop, switching to another source also causes a pop and so does turning off the amp in that mode. Again, no issue in the digital modes....

                Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
                by howardc64
                Failure Symptom



                No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

                Where is the short?

                Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



                Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...
