    Vizio m422i-b1 no channels

    Just picked this tv up for free. All hdmi inputs work but the tv does not find any channels when scanning with cable. I haven't tried with an arial antenna.

    Is this a main board issue? EEPROM?
    I searched on here but didn't find anything.

      Plug a 36" length of 18-20 ga wire in the antenna jack and scan for local channels and bend it vertically. You have to select antenna in the setup (somewhere). If it doesn't find any, I would suspect the tuner itself.

              Just tried the antenna. It picks up local channels. This is strange.

              Decided to try to scan for cable channels for the third time and it tuned them in.

                  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.

                  72 led total on 12 strips, 6 led per strip wired in three groups of 24 (led driver board has three anode and three cathode pins)

                  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...

                  Vizio SmartCast TV software bug that looks like hardware
                  by howardc64
                  Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.



                  It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....

                  Harmon Kardon AVR340 no sound on 4 channels
                  by r2digital
                  Hello, i had this amp sitting in the closet knowing that none of the channels were working. After taking it all apart i found 4 bulging main filter caps so i went ahead and replaced those with low ESR kmet caps. However after doing this it only restored sound to Surround L, Surround R, and Center channel. The main speaker fuse on the transformer F905/F906 keeps blowing so i decided to remove all of the transistor's on those 4 channels and measure them. All transistors appear to be in good working order(turned receiver on with none of them installed and fuse still blows). Checked dual emitter resistors...
