    I cut the two legs first then remove it by adding more solder to the tab, just be careful on those grain size resistors next to the legs of the IC.

      I just wanted to say thank you for all your posts. I didn't have to ask questions just read what was already said. I have fixed these 42" Vizio's before but this time I had a different problem. Usually it is the regulator U33 but this time that was not the case. The TV would turn on with no back light and would not turn off. The problem was U2 which takes the same part as U33 so I had one and installed it. Now the TV works and all I have to do is test it by watching something on it and messing with the menu. Thanks a lot to everybody.

        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...

        Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
        by Ierwin
        Hello everyone,
        Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
        The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
        He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
        I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
        Anyway I still fully expect that there has been something seriously damaged...

        what i went through dealing with my mobo with dead onboard sound!
        by ChaosLegionnaire
        so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

        i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

        Vizio M43-C1 - How closely do I need to match the mainboard number?
        by Devonavar
        I have a Vizio M43-C1 stuck in a reboot loop with no backlight.

        I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).

        Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346

        So, I've ruled out the PSU for now.

        The reboot loop...

        by maricm
        IH all, Got this vizio tv P65-E1 from FB marketplace hoping to be able to reflow mainboard as selerrstated that it was diagnosed with bad mainboard. However they must have tried to repair tv by putting another board in and they put P55 board in .
