Hello
My tv randomly restart.Show only Tizen and restart .

First make a backup of all dumps.
And test with W25Q40.
T-con only need if have picture issue.
the problem start this morning .First stop the picture and after some time i use to do reset factory. after that the tv work for 5min and the problem start again.very strange. two mounts after warranty ends !!!!!
Stop the picture and keep sound?
no. are not the backlight. i disconnect white and blue led protection and do the same.
i hope to don t be the led strip. i don t find nowhere.
If with spi flash memory dump not work you can try do USB upgrade with firmware update provided by Samsung: https://www.samsung.com/levant/tvs/uhd-4k-tv/tu8500-55-inch-crystal-uhd-smart-tv-ua55tu8500uxtw/
But the issue is very strange. Working 5 minutes before fail, normaly the software bug take effect in the starting proccess...
i ready try this. are some buttons to press(remote or tv) and after plugin the tv?
If the tv works well some minutes, you can do the upgrade procedure in the menu of tv.
I ready try but i ready have the latest version installed.
any way . I will try Monday to flash the t-con and i will see how going on.
Thanks for the quick response. keep in touch
