    Quoting Jack O'Neill from the famous SG1:
    "Well, this was an intergalatic waste of time..."

    Yes, upper buffer is bad.

    You need to replace the IC on it (about $5 each) or the entire board (pricey & hard to get.)

    You also need to replace the 88N30W FET on the upper most heatsink of the Y-main, closest to buffers.

    Tieny's thread is a good place to look as he had the same issue.

        well not a total waste got to test shunt regulator in breadboard learned there...but mostly waste agreed.... anyways i am trying to find tieny's thread no dice yet ...still looking and still a rookie to gettin around o forums lol

                    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...

                    PS5 digital / No Power / No Beep / Good power supply
                    by MisterAIL
                    Hi everyone,

                    Brought a non functionnal PS5. Apparently only a bad PSU...
                    No beep, nothing.

                    After some tests i found this :
                    - PSU is fine (12 volts stable)
                    - 12 volts line is shorted
                    - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
                    - By the way, nothing change. No signal, no power, no beep.

                    Mesuring all rails with my workbench psu (12 volts input)
                    - 0.00 amp drawing
                    - 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...

                    Fishing bite alarm drains battery
                    by Mcfeetroy
                    Good day to all. The bite alarm drains 9-volt Krona batteries. Current consumption when switched on is about 50 mA. I wiped the board from oxides, I will attach a photo (on the board there is a j3y transistor and a 7533 stabilizer, the microcircuit is erased = (the 3.3-volt stabilizer heats up weakly. I replaced it, nothing changed. I unsoldered the microcircuit, the consumption disappeared. The resistance on the pins of the unsoldered microcircuit from the point clockwise is more than 2 megaohms, the 11th leg is presumably ground. I warmed up the microcircuit, the consumption does not change....

                    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...
