    Vizio E370VA - Black/White screen, distortion.

    Make - Vizio
    Model - e370va


    So about a month ago I got this free Vizio tv. The tv itself powers up fine, and seems to work great. However, it appears that something that has to do with the color is messed up. The picture comes on but there is just no color, its almost as if its in a white mode, or black and white.



    *Note* When plugging into my computer through HDMI I get color(Extremely light tints of color), however, everything is extremely distorted, sound works fine though. What could this be??
    *Note* All blacklights appear to work fine

    I did a full system restore, that didn't work. So I went ahead and took the tv apart by taking off the back panel. I looked all over for anything unplugged or something simple like that. Nothing appears to be out of socket and all of the caps appear to be fine. I'm guessing its one of the boards but honestly I have no clue.




    Now instead of just trashing this thing I would like to see if I can fix it for a reasonable price and throw it into my game room. I have noticed I can get main boards on ebay for around $50.00, Power Supplies 30.00.

    I suppose it could be a power supply distorting things, which would make sense.. I think.






    Any suggestions guys? Could really use the help!



    Thanks,


    - Obz

      I actually considered that. Do you think the ribbons could be bad?


      All things point towards the tcon or power supply from what I have gathered. This is my first repair so I am pretty much a noob to LCD's.

        It looks like Gamma Voltage problem on the T-CON board.

          I believe it is the T-Con board after doing more research. I don't see any signs on the power supply and I have properly tested each board with a meter.


          I'm going to go ahead and order a new T-Con board and hopefully that fixes my issues.

            Just ordered a new T CON board off ebay. I suspect this is the cause of the problems.



            I'll update the thread and let everyone know if this resolved my problems.


            Thanks to budm and Glitcher for your help!

              White screen repairs
              by harp
              To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
              Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
              On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

              Vizio TV M50-C1 reboot cycle and static on screen
              by spice_disc
              I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

              The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

              Sharp LC-65Q620U White Screen
              by EazyBone
              Another TV topic!!
              I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

              The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

              Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
