    Vizio D650i-B2 stuck on logo

    I'm working on a Vizio D650i-B2 for a friend. It turns on and displays the logo and then freezes with the logo on the screen. Before I worked on it they left it on for hours without it ever changing. At that point it won't do anything. I can't even turn it off.

    I have a decent background in electronics but I'm old school and behind the times so this thing is a bit baffling for me. I did a quick look on YouTube and found a video posted by shopjimmy showing the problem and they said it's usually a bad eeprom and if not that it's usually the T-con board so I ordered a T-con board figuring it was the safest way to go.

    Unfortunately I have the exact same problem with the new board so now I'm lost and would appreciate any suggestions. I asked someone at shopjimmy for suggestions and they sent me here...

    I searched the forum for this problem and I found some similar but none quite fit these symptoms.

    Also, I don't know if it's related but it's been troublesome even before this problem. It had a tendency to freeze while watching streaming movies, etc and would become totally unresponsive. It had to be unplugged to get it to work again.

    But the current failure seems to have come after a thunderstorm so the 2 problems may be unrelated.

    So you did not replace the EPROM chip?

    Or may just be better off picking up a main board if unable to find a replacement eprom. I would probably just replace the main board just to be sure since you stated other issues as well.

      Great... in my first post to the forum I've managed to establish the fact that I'm an idiot. :-)

      Somehow after watching several videos and reading posts I mistakenly decided the eeprom was on the T-con board so I figured replacing it was covering both bases.

      I still can't find anything conclusive but it would appear to be on the main board. I can't find anyone that sells the eeprom for that model so I apparently need to order a main board.

      So before I make another idiotic mistake could someone please verify that it is on the main board for this model and that it is the most likely cause of the problem? Of course if you know of a supplier of this eeprom that would be most appreciate too because the board is pretty expensive.

      Thanks for the help!

        since you are thinking of replacing the main board (maybe), why don't you try reloading the firmware (via usb if possible) and see if that helps.

          Thanks, that sounds like a great idea but I don't have a clue where to find the firmware or how to reload it so any help in that direction would be GREATLY appreciated!

            :-( doesn't look like they offer a "usb upgrade" method.

              I saw this posted in another thread for something else.

              This was posted another member "jeh245"

              "BEFORE YOU buy a new main board board for any Vizio TV that is stuck on the Vizio logo try to reset the tv by doing these steps. I had to turn tv on then hold down on menu on keypad and press menu on the remote then release menu button on remote and press 1991 on remote then let go of menu on tv. Once your there go down to reset tv and it should re flash eeprom chip and that's it. It worked for me."

                Thanks, I'll give that a try. It'll be Wednesday before I get a chance to look at it again but I'll report back and let you know how it goes.

                  hope it works... I was looking for the "reset" sequence but could only find one which was showing a "menu display sequence" which isn't good if you can't get thru the display.

                    Sorry I didn't provide an update sooner but I haven't had much time to work on it. I had planned to try the reset information provided above by splatee but I realized this TV doesn't have a MENU button. The only button on it is a power button. I tried holding it on as I plugged it in and using the remote but it wouldn't respond.

                    Next I removed the main board and found a small burned spot on it. Looks like a resistor or cap was nearly vaporized. :-)

                    So I ordered a main board from shopjimmy and it arrived yesterday and that took care of the problem.

                    Thanks for all the help and suggestions!
