    Vizio M552i-b2 intermittent screen issues

    Purchased a Vizio M552i-b2 tv that wouldn't power on. Took the back cover off, and inspected everything. Didn't see any popped caps, or anything like that. Figured it was an issue with the power supply board, so I went ahead and ordered one. Installed it, but that didn't fix the issue.

    After the power board didn't fix the issue, I went ahead and replaced the main board. Lo and behold, the tv powered on. However the screen was red. Also, the menu with the inputs is jumbled.

    power up screen looks normal Disregard that light, that's a reflection of the power indicator.
    netflix menu screen looks a little dark, but normal
    playing something from netflix however, does not
    netflix menu with jumbled input
    tried an HDMI input, with the same issue

    I didn't get a good picture of the screen when it's red, but if I turn it on, but don't select any inputs, the screen is red. The "no signal" part is pretty dark too.

    Anyone have any ideas on what the problem may be? Possibly a bad main board? Maybe a problem with a ribbon cable? I can't figure it out, and I'd rather not just keep throwing money at it. Any and all help is greatly appreciated. Thanks!

    May have to look up how to enter service menu and see if there are panel options to select

      I looked up how to enter the service menu, but what options would I be looking for in there?

        Were the printed numbers etc on label/s on the replacement board the same as on original. The main board is usually set up to produce output for a specific screen.

          Honestly, I didn't check that. I looked and all of the ports are in the right place, etc. I'll double check that this evening though and report back.

            Ok, so I took a look, and they differ slightly. Printed on the board of the original one is:

            Lakers 14M 49/55/65 MB
            13084-1
            748.00714.0011

            On the new one I put in is the following:

            Lakers 14M 49/55/65
            13084-1
            748.00713.0011

            So, the only difference is one is .00713 and the other is .00714.

            Should I order the same one, and see if that works? It doesn't seem to be an issue with the panel itself, does it?

              Have you accessed the service menu for panel options,lvds etc?

                No, I haven't had the opportunity to do that yet. I should be able to this evening though. Anything in particular I should be looking for within that menu?

                    Thanks for that! What setting/settings should I be looking for in particular?

                      Maybe pictures of your service menu. Is it readable?
