    Vizio P50HDM picture flicker and red sparkles

    After getting this plasma tv picture going it now has red sparkles across whole screen and screen flickers on and off(menu and display also).
    When I plug it in the screen flashes once and then front stby led blinks green 10 times and then solid amber.
    I press power and it turns on fine but with screen flickering and red sparkles.
    VS and VA are both stable at 59.1v and 197.1v.

    Any suggestions besides adjusting VS and VA voltage on power supply?

    Update- I will see what I can do with this info after I fix the flickering..

      I think there's a video on YouTube that shows a flashing screen on the same set. According to the video, the zsus was the problem. I'm on my phone or I'd post the video. Just do a google search for p50hdm flashes.

      Edi: I was half right. It's the 42" version.

          I saw that video and wasnt sure about it because mine just cuts in and out similar but No color, blurryness, or distortion issue.
          The first time I plugged it in after getting ysus repaired it worked fine for the 5 min I had it on then I turned it off for the night. I put the whole thing back together the next day and stood it up on stand.
          Since then it flickers
          I have double checked all connections

          Would a bad panel wreck the zsus?

              by csmith
              I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
              Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
              supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard

              by gavric
              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...

              Vizio m65-c1 picture flashing on and off on the screen
              by maricm
              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.


              Disconnecting left and right ribbons on...

              VIZIO E70-E3 Half picture with half TCON
              by Fly_Among_Stars
              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...
