    50pk590 working but in green

    Hi

    My lg 50pk590 wouldnt switch on (switched on but with a glow no picture or standby light)- so I took a main board from mates tv and tried it in mine and the tv came on as it should.

    I got my hands on a replacement board with the same ETB number. The tv turns on as it supposed to - but with a green background . Please see attached photos.

    When I press settings there is also a hint of green.

    Has anyone come across this- any help would be appreciated?

    the voltages were all within a volt

    (I cant run the test patterns becauseit doesnt seem to have ext autogen on the tcon)

      Is there any way of tweaking it in the hidden menus - or is it just not worth the hassle?
      But when I run the options after orbiter (used to get of rid screen burn) the display is as it should be.

      Thanks for the response

      or tweaking the set up and set down etc?

        It does , you just don't know because it's not labelled.

        Join the 2 pads R51,R52, that's the autogen

          Ensure all ribbons and connectors clean and seated properly.

              I dont think you can set it up for another panel matey, best go with a board for that exact tv.

                Thanks for the info

                But strange thing is I decided to play the games that are built into the set and a couple of minutes later the green actually disappeared.

                It started to act like a normal tv. But then when I turned it on and off the green was back again and then it turned to black, what I mean normal no green.

                  Maybe you need to uplug and reseat all your connectors again?
                  Willing to help but I'm no expert.

                    Re: 50pk590 working but in green

                    I switched the tv on today and theres no green screen. (display menus are fine).

                    However I've still got a little green tint around the lg logo cube. I'm also getting a green flicker around images on a dark screen.

                    I then reseated the Tcon to main board ribbon several time nothing changed.
                    I've changed the Y sus still no change.

                    Shall I reseat the buffer ribbons etc? Any ideas would be appreciared.

                      Try pressing on the mainboard, its not the buffers it will be a Mb issue IMO.

                        Re: 50pk590 working but in green

                        I changed the Tcon board and its fine.

                        The Tcon board replacement came with the replacement MB board. ( All from a donar 50pk590)

                        Is that normal?-EAX numbers were different on the main boards, But EBT numbers were the same.

                        But tvs fine now thanks for the help

                          Must be a Bga solder issue on the Mb very common on that chassis. Keep us updated on what happens

                            LCD TV Green/Pink screen problem
                            by jimjoe123
                            I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

                            Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

                            Then each time...

                            Dell Optiplex 5050 SFF - strange behavior and service_mode jumper not working anymore
                            by MMH3
                            Hello,

                            i have many 5050sff. all of them, and how i experienced over many years for all about 250 DELLs goin through my hands, are fully flashable and can be serviced in any way when the service_mode jumper is set.
                            Never ever i experienced problems with that.

                            Now i have one 5050sff machine, where this jumper isnt working at all.
                            I do not get the normal messge that the jumper is set when booting and a short test with FPT just confirms this. Everything is locked -->> EVEN for reading !?

                            The history of the machine is that i used it in my office...

                            by DynaxSC
                            Hi,

                            I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
                            There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
                            The board is generally working now, all PCIe ports are working, Windows installs normally.

                            However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
                            The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA...

                            Hi i have one Macbook Air 2020 where touch ID is not working (it's not scanning fingerprints). Touch ID was working before, there is no error message during scanning fingerprint it's just not scanning on screen you can see only fingerprint but there are no red updates as when it's working. Power button is working fine.

                            I've checked boardview and also schematics but i'm not able to find anything related to TouchID ... i have similar issue on a2338 where there was problem with PP3V0_TOUCHID​ and after replacing UT610 it was working but here i'm not able to find anything related to...

                            2011 MacBook Pro 13 green light, but not working
                            by ohnuts
                            Hello,

                            I have a 2011 MacBook Pro 13" as described in the title, specifically an A1278 with the 820-2936B logic board.

                            It was sitting for a few years, I booted it up to make a backup and install fresh during which I noticed the 100% fans and 90C temps on the CPU so, as I usually do, I opened it to refresh the thermal paste on the CPU and give it a good clean on the exhaust side.

                            It wasn't easy to get the board out, and it actually ripped a bit of the black insulation that is covering the backside of the keyboard, around where the CPU is. That's fine,...
