    "i switched it on something made a pretty big bang" I would first inspect it real well to see if there is any blown parts inside. Pictures of the inside?

        Budm, that is very diplomatic -
        "I pluged power in to it and as soon as i switched it on something made a prety big bang and no it is completely dead with no signs of power is there any ways i can repair it?? "

        I was thinking along the lines of " how the hell would we know"
        Please upload pictures using attachment function when ask for help on the repair

          So I opened a power supply that had been hit by a power surge and the fuse is gone and two 16n25c mosfets are shorted. I am not that good on crossing mosfets but I have two smk1430 mosfets which are n-channel and I wondered if I could use them or do I need to wait for the actual part for a week?

            Pictures and model number of this power supply? More likely the IC that drives the MOSFETs will be damaged also.

              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 M65-C1
              by mrtek
              Hi.

              picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
              When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
              This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...

              Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
              by howardc64
              Failure Symptom



              No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

              Where is the short?

              Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



              Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

              Vizio SmartCast TV software bug that looks like hardware
              by howardc64
              Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.



              It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....
