    Re: LG 60PY3DF shuts off

    What I'm trying to see here is if the CPU gets a signal from the fan will it then behave and will the TV turn on and stay on? One issue is this does not fit with your friend's description of slowing getting worse, lasting less and less time. I would expect it to just fail one day. Unless it were a cold solder joint for one of those connectors on the fan or a loose fan connector.

        nevermind, I know what you mean now. Let me put it back together and find out.

            I bridged by using those resistor from earlier in this post and one fan worked. Would I need a regular piece of wire instead?

                Yeah, the resistor will not allow enough current. 100mA typical - voltage drop 22V... from a 12V supply, that's not going to work.

                    Well i use 3 paperclips to connect the working connector from main board to both fans. After a few seconds both fans did spin but then the tv shut down like it always has.

                        I have the same problem with my LG 60PY3DF.
                        It's turns off after 3-5 seconds
                        Was the problem fix?

                            Putting the tv at the end of the street. I wasn't wasting anymore time or money on this.

                                I had the same problem with my LG LG 60PY3DF-UA turning itself off.
                                The problem was the 2 fans. One worked and the other did not. I replaced one $20.00 fan and the tv is fixed. It stays on.

                                    Same tv, same problem. My friend gave the tv for me to work on. They use it with the back cover off. I can watch for hours but last few days just a few minutes then a few seconds. Both fans work. I tried most of the suggestions here that I can understand. There doesn't seem to be any caps bulging. There seems to be a buzzing sound which I am not sure is normal or not. Any other suggestions? There are too many boards to replace this tv.

                                        Just an update. I wedged a resistor on the ac-on and and stby5v and seems to have done the trick. Will update if anything happens.

                                        Can I get an explanation about the fix? Thanks

                                            It died after an hour and when you turn it on, shuts after 5-7 secs.

                                                Next day after several attempts the board goes into protection mode, no more staying on, I turn on the PSU fans starts directly turning, it used to not start until I press the pwr button, now it starts directly and fans spins, and shuts off after 3 seconds sometimes less, then won't start again unless I unplug the PSU and...

                                                After replacing this capacitors the laptop came back to work, I reinstalled MacOS and had no issues until I started to test Type-C ports. Sometimes the laptop shuts off immediately when some action with Type-C ports performed (charger disconnected or USB device inserted/disconnected). I checked Type-C port flexes, they are okay, but I cleaned them anyway. I can't see any signs of liquid...

                                                Hi. I have a pre-owned Dell Inspiron 15 7567. It worked fine
                                                During the first 3 days of owning it until Dell Update software popped a notification about a latest Bios version 1.15.0 and latest Intel ME Software update of which I updated. It rebooted and firstly, Upgraded Bios from version 1.8.1 to 1.15.0 then it started upgrading Intel ME firmware. After that update, my laptop shuts down without notice (Like thermal shutdown)
                                                I checked Thermal Paste on the processor and the Graphics Chip and it was dry. Replacing thermal paste has not helped me.
                                                Now I've noticed that laptop...

                                                I have a Hisense 55H6570F that gets the the boot loading screen for android and then shuts down. Oddly I hear a crackle on the mainboard as shown in the picture - nothing looks blown. The tv will boot every time, but when it reaches the loading statge of the anroid logo you can hear crackling on the board and it shuts down. What am I looking for (other than buying a new set) ? Inside the square is where I hear the crackling
