I wanna share with you my story of shock, frustration, hope, success and despair.
I have a Samsung TV model UN32D5500RG from 2012. It worked just fine till one day it got an update and it started turning on by itself, displaying Samsung Smart TV logo, staying on for about 20 secs (showing AV entry but not responding to any command from the RC), then off for about 3 seconds and then again back on, once and again...
I tried all the codes I could find online (INFO+MENU+MUTE+POWER, MUTE+1+8+2+POWER, 2+5+8+EXIT and holding Exit key for 30 secs. Nothing worked.
When I was about to give up, in my desperation I pressed all the buttons from my RC together et voila... it worked! Thinking the problem was solved, I turned it off only to have it go back into this endless loop again. Anyway, It helped me to find out there was nothing wrong with the hardware.
I googled even more and I found a guy who pressed simulaneously INFO+MENU+MUTE+POWER and followed by in sequential mode MUTE+1+8+2+POWER.
BINGO! I got the famous Samsung Menu and then I did a factory reset. It was the end of the nigthmare for a couple of months... until last weekend.
One more time, I got one of those hideous serial killer automatic firmware updates. I was naif (STUPID) enough not to prevent the TV from connecting to the internet, but Netflix has new TV series, so whatever... Again the same loop.
I was all calmed down and I tried the codes that saved me the last time... NOTHING. I held EXIT key for about 30 secs and I could go back into watching TV normally. However, when I turned it on it went back to the endless loop.
I´ve been trying ever since to enter the codes but got no results at all. Tired (and with sore fingers) I decided to take matters into my own hands and try a hard reset as explained by this German guy:

I joined RESET and SDA holes from the EEPROM with a paper clip, turned TV on, left it for 20/25 seconds and took it off. Nothing, or even worse... The TV kept turning on and off, however now it does NOT display the AV sign at all. It just shows the Samsung Smart TV logo screen, then a fully black screen and then off. Once and again.
I read here https://wiki.samygo.tv/index.php/UnBric ... PROM_Reset
that joining SDA to GND might do the trick. But it didn´t
Last but not least, I discovered that if I join RESET to WP (they are one next to the other- see pic), I get a "static white noise" screen, but equally unresponsive.
A friend of mine works in Samsung and he told me it´s not worth it to take it to the service. They´ll deem the mainboard as broken and charge me for a new one. I´ve read cases where even with a new mainboard after a few months they faced the same issue.
It is crystal clear this done on purpose by Samsung to force us buy new TVs (which I prolly will, but of course NOT Samsung).
Could anybody please help me? By now this is a personal challenge to me which goes beyond not being able to spend a few big bucks on a TV right now.
THANK YOU ALL!
