    Re: 4K Vizio P702ui-P3 No Picture, No power to T-Con

    Hello no 12 v to t-con defective main pwb.. if all other voltage good. common on set with years hours use the main micro develops cold solders due to heat as surface mount, note the size of heat sink verse chip . if the ground pins float the chip fails .

        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...

        Vizio E701i-A3 backlight only and now no backlight
        by Awsmessymail
        Hello all,
        I’ve tried to repair TVs in the past with some luck. Toms repair manuals got taken down and now thats a bit harder.
        I picked this TV up hoping for a quick fix. When the TV would power on, only the backlights would come on. The owner told me they heard loud screeching before it shut off. This alone makes me want to think the main board has an issue.
        As I researched, I found the TCON/driver boards were an issue on this unit. I went in troubleshooting the TCON but found good voltages on the TCON. I followed shop jimmys guide to test the transistors and they seem okay....

        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...

        Samsung LCD TV no picture backlight on no 12v at tcon
        by shelby5041
        hi
        i have a samsung lcd tv

        it powers on with sound and backlight but no picture

        all voltages from PS are good 12v 3.3v and 5v

        whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

        i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

        no 12v at the tcon fuse

        i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

        the odds of having 2...
