    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!
