    Samsung LE40B579 Boot Loop

    Hey there!

    I have a Problem with my Samsung LE40B579. Unfortunately I played around in the SM of my TV and tried to activate the “USB Features to play movies”. That worked quite well with a change of the model but after that only one speaker was working, so I went back to the service menu to switch back to the old model number.
    Since then my TV is in a boot loop and won't come up again. I've tried to go into the service menu several times, but it doesn't work.

    Any Ideas how to fix my TV? Would be really great if anyone could help me!

    By the way, I've already read about EEPROM reset but can't figure out where the EEPROM is on my board.

    Board Number: BN41 01167C MP1.1

    Greetings
    Mario

      Re: Samsung LE40B579 Boot Loop

      You would probably need to install a new main board to fix this, as there is no other way I am aware of to access the service menu.

          Hmm... Sounds not that good
          I looked for the Board on ebay and its about 100€ (~124$)

          Is there no other possibility? As i allready mentioned above, I've read something about EEPROM flashing? Isn't that worth a try?

                      Can you supply clear detailed pictures of both the top and bottom of the board?

                          I tried it. If it is not detailed enough i'll take 4 Picture (Left-Top,Right-top ....)

                              I've highlighted some POTENTIAL candidates. Please get the part numbers from each.

                              There may also be devices on the bottom of the board, so please take some photos of that side.

                                  Thx tom,

                                  I've taken photos from the back of the board. Furthermore i noted the part numbers of the highlighted candidates on the picture.

                                  really thx for your help so far!!

                                  I actually missed to mark/note the number from one possible EEPROM at the back_bottom.jpg
                                  Its the same number as the one on back_top.jpg

                                      Yet another Samsung QLED Boot Loop
                                      by Takeatry
                                      Samsung QLED QN50Q — purchased 2022 started experiencing a delay in the picture coming on in the morning less than 2 years later. Did not know the term boot loop at that time. As the loop delay ran into a few minutes did all the recommended troubleshooting, soft and hard reset, changing cables and outlet locations, no help. As the delay increased contacted Samsung tech group and allow them remote access the tv. Tech was moving too fast to see exactly what he was doing but this ultimately it was also no help. Lived with the delay until it stretched out over 6 hours. Pulled of off the back cover...

                                      by NolesFan
                                      Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...

                                      Samsung UN40H5003 boot loop every ~8 seconds
                                      by eigma
                                      Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

                                      Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/

                                      SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.

                                      Less than a year out of warranty, samsung UE49MU6105K craps out, they've got this designed obsolescence down to an exact science of self destruct when out of warranty...

                                      Screen started to show horizontal lines and ghosted image at the bottom, then turned off by itself. Did software update, to no avail of the line problem, and got a boot loop after some minutes of watching TV. This boot loop will turn on the backlights for some seconds the sound comes on, the image will turn dark very fast and then it reboots again. Pressing power button will not put it on standby. Disconnecting...

                                      Samsung UE49KU6500U boot loop
                                      by signedupfordownload
                                      Hello,

                                      My Samsung TV had a black patch on the left side of the screen for a while. One night it shut off and then became stuck in a boot loop. I initially believed the back-light was the issue and replaced the LEDs but it still boot loops. I've since replaced the main board and the issue persists.

                                      With the main board unplugged, it powers on and the back-light comes on. I've tried the tape method but I gave up as I don't know what pins I need to cover.

                                      I suspect the panel itself it broken but have no multi-meter to test. Is it worth investing in one to test?...
