    Vizio e550vl HDMI Problems

    I have a Vizio e550vl that up until a few nights ago was working perfectly. Woke up one morning and when I turned it on it was showing no signal on the screen. It is plugged into a surge protector, there were no electrical storms in the area when the problem occured either.
    It is connected to a Direct TV HD DVR, a Blu-ray and an audio receiver. Tried resetting the DVR numerous times to no avail, tried the Blu-ray which would not play thru the HDMI either. Swapped HDMI cables around with known good cables, swapped ports, turned TV on and off numerous times and finally the picture came back on the TV. Would only work on the top HDMI port on the back. Hooked Blu-ray up thru the AV cables and that worked also.
    Next day same thing, turned TV on showing no signal. Turned TV on and off. reset DVR and now it is working thru the HDMI port on the side of the TV but not the back. Also Direct TV has free channels available thru Dec. 1st and if I try to view them I get the following message, " Your TV does not support this programs content protection. Replacing the TV's HDMI cable with component cables will allow you to view the program".
    Could it be something as easy as replacing a board? I have not had the back cover off of it yet either.
    Any suggestions would be greatly appreciated.

    Any suggestions on this? None of the HDMI's are working now. Have the Direct TV HD DVR hooked up thru the A/V cables now and TV is working fine except for the fact it is in 480p.

    This TV has 3 HDMI ports, from what I seen on another thread these are basically routed thru one processor. Before I spend the money on a board has anyone else experienced this problem?

      Vizios are known for bad voltage regulators on the main board, I suggest testing those first before considering buying a new board.

            Did the factory reset a couple times, what started out as an intermittent problem with the HDMI seems to be permanent now. Have it hooked up thru the AV cables until I get time to open it up.

              Took the back off today, nothing obvious sticking out. The part # on the board is 3655-0152-0150 (4A) other numbers are OKM502A4V01904A AND CSD:3655-0152-0395. I found a board with part# 3655-0152-0150 (4G). Does anyone know if the (4G) is just a revision and will it work as a replacement to the (4A)?

                take a picture of the HDMI area. Plug in a HDMI cable with a live signal and power on the TV and check the HDMI IC chip for overheating.

                  Opened it up and took a couple pictures then closed it back up to watch the football games thru the AV cables. Could not see anything obvious around the chip. Lifted the board and looked at the back and the board looked good.

                    I took a chance and bought another main board part #3655-0152-0150 (4G), the board in my TV is a 3655-0152-0150 (4A). With the original board installed as soon as I plug the power cord in you can here a click on the power board, the TV will power on and everything works except the HDMI.

                    With #3655-0152-0150 (4G) installed there is no click on the power board, the VIZIO light on the front of the screen does go to orange but the TV will not power on.

                    I thought I may have made a bad connection with the ribbon cables or the other connectors on the board so I swapped the boards back and forth a few times with the same results.

                    Boards look exactly the same except for the (4A) vs (4G) designation at the end of the part number. Does anyone know if the revision is that critical to the TV powering on and working or am I missing something obvious?

                        Try a firmware update/reapply.

                          Try unhook everything except dvd player, see if it works thru hdmi, taking direct tv out of equation.
