    Vizio m3d650sv no led logo, surge from lightning

    Hello guys. I have a vizio M3d650sv that was in a house struck by lightning. The tv logo will not light up. Hitting the power button does nothing. I checked the standby voltage and there is 5volts going to the main board. I have checked diodes, resistors, and some capacitors. I also put 3.3v on the remote pin and get 12v, 18v, and 24v on the other pins. However, at the lower part of the board, i hear a faint clicking aound every couple of seconds. As long as that is normal, then i assume the issue is in the main board. I am lost at what to do next. I cannot find any schematics. The power supply board is available, but the main board is not anymore. The power supply board part# is a Vizio 0500-0507-0920 (delta ps DPS-353AP). The main board part# is Visio 3665-0042-0395 (AmTran 3665-0042-0150(4b)) sn: LATAMEAM5001515.
    I have called and emailed many places to get schematics or options and no one will help even if I offer some money. If anyone could point me in the right direction i would appreciate it greatly. Thank you.
    I will try to get pictures up asap.

              I don't know much about these vizios but can you take a close up of the main board?
              By the looks of it,the main fuse blew and you put your contraption in ?
              When you measure the 12,18 etc volts on the power supply,are they steady or fluctuate with the "clicking" you hear?
              It's not uncommon that when lightning strikes,a tv gets a double whammy,it hits them in the power supply and also hits them on the mainboard via the incoming cables from the cable box etc.

                  Yes the contraption is another ceramic fuse. I just threw it in there for testing because no one around here had the solder in fuses. I do believe that they fluctuate voltages with the clicking sound.

                      Exactly what did you mean "put 3.3v to the remote pin"?

                          In other vizio posts, you disconnect the main board and externally give the remote on/off pin on the power supply 3.3v to test the board by itself. This should give you 12v,18v, & 24v respectively.

                              Vizio M65-C1 | Logo appears for 10 seconds then off
                              by Bob1394
                              I have used the search, and am stumped.

                              My Vizio M65-C1, Vizio logo appears for about 10 seconds then goes off.Power LED blinks 15 times then the TV powers down.

                              I have read through many threads on the M65-C1 including the following threads. I feel like I must be looking right past the solution to my problem:

                              Vizio V555-G1 stuck on wallpaper; now stuck on V logo
                              by x_orange90_x
                              I just got this tv today and it's getting stuck on the wallpaper. When I first power it on it goes to the V logo, then a black screen for about 15 seconds, then a Chromecast error for just a few seconds, and then finally to a wallpaper. It stays frozen on this wallpaper and does not respond to anything on the remote besides power on/off. Likewise the buttons on the tv do nothing either (besides power). I did the "reset" by holding the volume down and input buttons together for 10 seconds. It showed a message at the top of the screen saying it was Wiping Data and would restart soon. After...

                              Vizio D32f-E1 Powers on, has backlight, won't boot/no logo, no menu or video
                              by JaquesPratt
                              I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

                              This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....

                              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                              by Tynan Dill
                              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                              Upon bringing it home and plugging it up, it showed a standby light.

                              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                              The screen seems to blackout and stay black, but with a flashlight I can see the display.

                              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                              Assuming...

                              Vizio E701i-A3 stuck at logo, need service manual
                              by paulxxxx
                              The TV stuck at logo and cannot be turned off unless the cord is unplugged.
                              I was given two main boards and exactly the the same thing happens to both of them.
                              I have checked all voltages on the connector on the power board that goes into the main board and they all look OK.
                              There are no signs of damage on any of the 3 boards.

                              Would someone help me with a pointer to the manual? It's supposedly to be the same as E601i-A3.

                              Thanks!
