to me is the closest fix
I also have this or similar with a 32D5520, 5 years old. It shows the Samsung logo and you actually get picture and sound
but no on-screen overlay at all. I read that the watchdog trips if the software can't boot after a time (in my
case 5 seconds) the power will cycle.
There are no blown capacitors but I checked the PSU board was fine by doing a swap.
I tried connecting SDA to GND on both the EEPROM for the Sub-Micom and the main processor (IC901/IC1203) after reading
up on these forums in the hope that the EEPROM would be reprogrammed or it would boot up some defaults but no joy
Looks like new mainboard because my soldering is not that good! Disappointed because it was a good TV.
Its now in storage waiting for a cheap mainboard to come up but if anybody has any suggestions it would be
My TV was repaired by changing the main board, it was working for 10 months and now the problem is similar but not equal.
problem one year ago was i turned on with my Remote C, it would show the samsung logo for a few seconds, then shut down and turn on by itself and stayed doing that.
Now it shutdown and restart every 2 or 3 minutes en the middle of being functioning and keep doing that
please any ideas ?
If your TV uses main board BN96-21113A or BN96-21111A then IC1301 is your issue. It is more than likely a physical issue with the chip. If you freeze the chip with an upside down can of compressed air, it should allow your TV to work temporarily. This will confirm that indeed you have a bad IC.
When you have that type of NAND chip on a samsung board and your problem is a cycling issue, it doesn't matter if the cycling happens every 5 seconds on the dot or every 15 minutes on the dot, it will be the same issue just a slightly different variation of the same failure on the same chip.
If the cycling varies in time, then you may have a different issue.
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!
I just can say, friend of yours is right. Online update failed and your tv bricked without chance to repair at home. Some vital partitions were brocken so that without re-balling the main tv's storage - emmc/oneNAND with properly flashed firmware on it, chance to repair in other ways are equal to zero. I can't remmember any single tv brick with such anamnesis, to have happy end. Always the same-after all possible known methods of resuscitation, mainboard replacing by warranty or by expenses of owner himself was the logic final.
