    Vizio vp50 hdtv20a

    Can anyone help me out with the 3 adjustment knobs on this board. Its lj41-04217a. Just want to know what they do and if they change voltage where do I test the voltage at. I adjusted the one on the x main by using a multimeter on test point but I don't see Any test points On this y main

      The adjustable points on this usually control timings and peak voltages, which can only be adjusted precisely with an oscilloscope. But it's still possible to adjust them by eye -- looking closely at the plasma panel while it's working.

              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...

              How Can I test PWM DM0365R?
              by chth96
              Hello
              I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
              So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
              I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
              I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

              test active pfc power with lamp test
              by khelane
              Hello
              I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
              Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
              Is there a way...

              Mats / mods: detected and repaired GPU fault. Cant seem to test after!
              by chronic519
              Hello.

              GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
              Found issue with a RAM block
              Replaced, green lines gone.
              Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
              Used a good card to test and same results low errors 32+.

              I am just search for some form of command to do a full test on the GPU.
              I just ran the mats command with my good GPU and passed after roughly 40 min.
              The repaired one, ran...
