#2 - Repair of Samsung Smart TV UE46D5700 - stuck in boot loop 

Same here. Did you manage to find a solution for it?

@@shaazy not yet, finishing the repair had been delayed a bit. I was considering just replacing the entire board but then I have to be 100% sure it's not the power supply. I will post here if I have an update. Let me know if you do too please.

Hello Sebastien, 1. It depends where you live, try to find it on ebay by searching for "K9GAG08U0E Samsung". There should be suppliers who are able to program the IC with a suitable firmware for your TV. 2. There are many ways to solder the IC, i prefer to use my lovely DIY JBC iron with small tipps. Maybe i should show the hot air method at the next repair job. 3. Basically you need to interrupt the I2C communication of the EEPROM. The SDA(data) & SCL(clock) are pulled-up to VCC by a resistor, and the EEPROM acts as a open-drain and pulling the lines low to communicate ( see en.wikipedia.org/wiki/I%C2%B2C#Design ). So shorting SDA -> GND should do the job! If you short it to VCC, then the EEPROM makes a hard-short, and probably will not survive this. It is better described at wiki.samygo.tv/index.php?title=UnBricking_TV_by_EEPROM_Reset Good luck & keep me posted how it's going

@@WaldemarHeimann Thanks for answer, when i asked i didn't open my tv, after that i understood when i saw the pins. Anyway thanks for all those informations and your video, should help others.

Hello, if you changed the Main board, then it should be EXACT from the same tvmodel, otherwise you need to reflash it with the right firmware. There should be only 3 Boards: Power-, Main- and TCon-Board. So if the above try didnt helped then the last one would be the TCon Board. Again: you need to have it from the same tv model or to adopt it via firmware flash procedure. Good luck!

Hallo Andreas, bei eBäh finden sich einige Verkäufer, die den "Service" anbieten. Das IC leer kostet nur wenige Euro, dieser wird aber mit spziellen Tools/Programmern mit der zu deinem TV passender Firmware vorprogrammiert und deshalb sind die Preise dafür um die 20€. Suche nach "K9GAG08U0E Samsung" und du wirst mehrere Anbieter finden. Ich darf hier leider keine "externen" Links posten. Du wirst beim Kauf, als Kommentar, deine genaue Modellbezeichnung mit angeben müssen. Kleiner Tipp noch: Achte drauf, dass du wirklich "in Deutschland"/ bei einem deutschen Anbieter kaufst. Lass mich bitte hier wissen, wie deine Reparatur gelaufen ist. Über ein Abo würde ich mich ebenfalls freuen!

@@WaldemarHeimann Hallo Waldemar, hab den Bauteil auf unter -4 Grad abgekühlt und nun funktioniert der TV wieder. Dann noch gleich die neue Firmware draufgespielt. Werde jetzt noch zuwarten ob der Fehler wieder kommt. Lg

@@prunthallerandreas3717 das ist super! Gehts noch?

@@WaldemarHeimann ja bis jetzt funktioniert es.

Danke für deine Unterstützung. Es ist eben so wie es ist.

Ebay, but there are a lot of fakes. Good luck 🤞

Hi, i don't think you will find a schematic for it. Try to follow the PCB track of the ripped off SMD pad. Use a magnification lens and a multimeter with contenuity test and i promise you that the next connection point of that signal is not far away. Unfortunatly i can not help you because the TV is already assembled and therefore i don't know the PCB name. I don't think i am allowed to post links here but if you use google with "ue46d5700 schematic" you will find some free service manual documents on the page of "elektrotanya". Give me feedback here if you are successful! Best regards, Waldemar

Has no track,no lines is on the other side of the arrow , arrow left and my problem is in the right side

It is for sure also possible that not every pin has a function and therefore no connection, just a smd pad without a connection. They are called "NC" for "not connected". My hint is that you need to look in the datasheet of this part and this specific pin to know if it is such a NC pin or something else. Finding the datasheet is easy, just type the marking of the IC in google: e.g. "K9GAG08U0E datasheet" and look up the pin description

@@WaldemarHeimann thank you !!!!!

Is N.C thanks

No i didn't, because its not possible. Maybe you get me wrong? Which timestamp was it?

@@WaldemarHeimann Oh sorry, I couldn't hear it's an ESR meter, because it looked just like an ordinary analog meter. That was at 5:00

@@Mikkelssoni oh yes, i forgot about my ESR meter. The housing is from an old cheap analog Multimeter

Hi, how could i help you?

@@WaldemarHeimann Tell me how to repair my SAMSUNG SMART TV UN46D6500VF - Stuck in boot loop. Thanks.

@@alphonsentawuyamara5108 i explained two (common) of possible x reasons for this issue in my video. In this TVs are a lot of complex electronics so it can be everyzhing that causes a bootloop. Have a look on the other comment where i referred to a Samsung forum with more solutions. Hope this will help you. Good luck

@@WaldemarHeimann Thank you so much. What do you think about to replace the main board?

Could be a successful but expensive repair. Regards
