Suddenly my UE40D5500 stuck in the last channel I had seen and displayed nothing. I powered off and on and still nothing. So i did an Epprom Reset on te board and now I have stuck in a boot loop, in which as soon as I put my TV on the main power line the TV switch on automatically, and displays for 2 seconds the logo Samsung Smart TV, then black screen and after 10 seconds this is repeated.
I have also constructed the VGA link cable to serial and in my console I see the following messages:
Switch to Earphone UART
Switch to Micom UART
onboot (Feb 25 2011 - 16:08:03)
release ver : 1002 - RELEASE
Onboot X6 Sync mode
LCD FastLogo Run...
load kernel start, size : 131072 + 3538944 byte
auth success by h/w sha1 UART1 is used to UART or logic mode.
I have tried many times to do EPPROM reset but nothing happens. I have left the TV for many hours, nothing changed. i have removed the power for 1 week, nothing changed.
I am attaching pictures of the mainboard.
what should I do?
Thank you very very much in advance. Please give me a tip...I know a bit about electronics as a hobby so be free to give even advanced technical details.
