    Sad to hear this.. i have put my efforts to follow this case.. then it comes the same old troll that discourage the turn user.. ok but think again what you do, you can't diagnose things without tests.. i'm afraid that someone self elected "guru" is one that not even know the basic ohm's law.. ridicolous! This is the TV saver...

      You're right, but i'm work hard during the day and i don't have time to fight with anyone or having bad mood. So now I don't want to do anything. Word is full of donkey and you will understand what I mean. I really appreciate your time and guidance. But it's time to put the tv off . I really upset of that then i don't have any more time for this old tv. Thank you

        i wrote the original LED strips their LED unit build in ziner diode... the strips will work under Original : 167V, the neu in market with out ziner will need less 155V​.... this why i listed before 3 parts need to change

          Pr=3,3*0,55=1,6W
          as lotas said..... yours way will kill the PSU...you are free to do any experiment on yours own sets not other users. end.

              change
              R6853 (100ohm)
              C6826 (1uF 10V)
              PS6800 (500mA) replace it with Zero Ohm R
              ​
              Morning do you mean this?

                            Hi here all components that I changed. According to you it's should be working but not, I take some measurements again and it's seems i don't have anymore power on out of t-con...😫 thanks

                              why you changed R6850?

                              it seem my act was late after yours post #88 by making hot air fried crispy machine..
                              R010 are higher than 0R --- it sound close value but its place as its Sync R play big issue with currents..

                              solve first your issue with power on etc.. i cant review what you did before..

                                You have a native 2.2 Ohm resistor (current sensor), why did you replace it with 100 Ohm? Do you think that after such a replacement the circuit will work?

                                  I changed the 100ohm resistor because is mentioned
                                  here of course it's a little difference with mark on it so I supposed it was the same. (Mistaken). Anywayit's not a problem tomorrow I'll put bache the original..

                                        Men first of all, thanks for the reply. Second, I already changed the smd capacitor , and I the resistor smd if you look the picture above you'll see.. Tomorrow I'll replaced the original resistor and see what happened..

                                          Hello guys, so I replaced the original resistor back, the tv turn on and then back off, the red led blinking 6 times, I look beyond of the chassis and seems one side of the tv the light is less than the other side.. How's it possible 😫😫

                                            Looking for eMMC Replacement for Sony LG 60la620s EAX64797004 (1.1) with Boot Issue
                                            by timonix20
                                            hello everyone I am looking for a solution for my tv, I think corruption of the eemc,

                                            the TV starts, LG logo, then nothing (rear backlight)
                                            no reaction to rear command or infrared


                                            the usb procedure that I tried on the LG site is a procedure with the screen and the remote control so I can't.


                                            I have a chance with a usb procedure or other if you have .bin

                                            if any people have this main board

                                            Sony LG 60la620s EAX64797004 (1.1)




                                            thank you...

                                            PS4 controller left stick potentiometer replacement issue
                                            by ezenia
                                            Hello,

                                            Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

                                            So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

                                            I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

                                            Sony MDR-IF245R transmitter LED replacement
                                            by lti
                                            I'm looking at the transmitter from these wireless headphones because the range is too short. One of the LEDs failed many years ago (nine years ago - I found pictures that I took then) and was simply bypassed to make them work again, but it seems like the range has been degrading since then. They're near-IR LEDs (I can see them dimly lit red, so they aren't the standard 940nm), and I haven't been able to find the actual wavelength. Does anyone here happen to know what replacement LEDs I should use? Maybe I can adjust the transmitter was well while I'm in there, or there's another fault. I should...

                                            Samsung UE48JU7000 screen issue after backlight replacement
                                            by ScHAmPi
                                            Hi all,

                                            Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:


                                            I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...

                                            Sony Bravia KDL-70W850B T-CON board / software update issue
                                            by eclectric
                                            Hi, I'm hoping someone can help me with this issue before I give up on this TV.

                                            In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.

                                            Here is a rundown of the symptoms and the steps I have taken to troubleshoot:

                                            I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes...
