    Lg 50pb560b-ua

    I have the above set with a bad M.B. but a good Power supply. I want to do a screen test to check the panel before proceeding. I could not find a Service manual or a set of schematics.
    Does anyone know how to jumper the Control board EAY63168601 for self test to verify the panel and other boards are good? Do I jumper the two pads
    between IC704 and R451 and R452?

          Ok thanks. I thought that would be it but I wasn't sure due to no
          Service Manual, Schematic. I will do it tomorrow. Thanks

              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...

              Lg TCon test pins for screen test
              by alltvrepairs
              Hi,
              i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

              Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

              Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

              Appreciate your help....

              HP EliteDesk 805 G8 "PSWD" Jumper
              by blankdisplay
              Hello,

              Apologies, I broke a rule and hijacked a thread, so I deleted that post.
              I am curious if anyone here owns the G8 or has good quality board shots?

              I've done some googling and curious if the 805 G8 series has some kind of jumper?!

              The 800, G3 series, much older, the maintenance and service guide, clearly talks about a PSWD jumper

              I also believe it's just visible in this shot:
