    Vizio VF551XVT troubles

    We Have a Vizio VF551XVT that suddenly quit working while my father, who can open an email and reply but will not send one, was staying at our house. I ran him through a few setup options but got no where.
    Upon arriving home we found that the remote had no effect at all.
    I could turn the tv on with the power button but the only picture was the blue screen.
    I tried all of the HDMI ports and still nothing. (our cable box is connected through the HDMI port)
    I had an digital converter box and hooked it up to the yellow, white, and red ports on the side of the tv (component 2). This gave us a picture and we could change channels but there was no sound.
    I investigated possible solutions online and dismantled the tv.
    I took voltage readings, with the tv on, at all of the identified terminals of the DPS-433BP-3 main board. All voltages were as listed.
    I checked every capacitor on all of the boards an all appeared to be fine, no bulges or defects apparent.
    The only thing that caught my attention was a blinking red LED labeled "D302" on board KLS-550WLTD(2) Rev:1.2.0 . I have not been able to find any information on this.
    I would appreciate any input that helps me solve the problem.

    Thanks,

      Can you post a picture of the mainboard?

              Has the picture of the board come through?
              Is there anyone there?

                      Well, some people don't seem to realise that others have a life outside of Badcaps (as strange as it may seem!) Ugh, entitled generation, or just arrogant?
                      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

                          wow,well sorry sir it fell through the cracks,a gentle bump would have been a better option...
                          Good luck on the repair,I'm out...
                          P.S,I asked for a pic of the mainboard,NOT the powersupply.

                                  Hello, i am working on Vizio M70-C3. It can hardly power on, it takes 15 power button presses or remote. Seems like eeprom problem that I seen before but all reading online says that this tv has power board or main board problem.

                                  Vizio M65-E0 No Picture, No Sound
                                  by ggil44
                                  Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...

                                  HI all,
                                  hope someone point to the possible issue before I start buying replacement parts.
                                  Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
                                  Backlight stays on all the time,
                                  Sound works fine.
                                  screen keeps changing form black to full picture in about 1sec intervals.
                                  Picture looks fine with no visible artifacts.
                                  I have disconnected backlights and flashlight test confirmed that picture is still doing the same.

                                  VIZIO E70-E3 Half picture with half TCON

                                  Hi,
                                  I have a VIZIO E70-E3.
                                  Symptoms: Black screen, no picture, but LED backlights are working.
                                  I probed the power board and voltages are as listed on the board.
                                  Main board appears fine, too.
                                  I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
                                  There are two separate ribbon cables feeding the LCD.
                                  If both are connected, the screen is black.

                                  If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

                                  T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)

                                  Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

                                  The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

                                  Original T-con:
                                  Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

                                  First replacement T-con:

                                  I thought it might be t-con and ordered new t-con from china(supposedly tested)...
