Since I have no sounds too could it be instead it is a mainboard issue maybe not able to boot properly? I have checked mainboard supplies and they seem ok. in case of panel issue can it be fixed?...Leave a comment:

lotas[USER="169795"]lotas[/USER] do you suspect already something? one of the 2 panels issue? I'm slow on providing info about the test you have suggested since I'm ordering a connector on the T-CON that is not perfect. I have ordered a new T-CON too.Leave a comment:

Hi Bohaboha, trying to supply the board for a raw sanity check. I was expecting to have LED3 on too (the boost section) but I guess there are firmware dependencies. Another detail: when I try to turn on the TV the power state red LED is blinking slowly 4 times....Leave a comment:

Hi all, thank you for the quick reply. With the TCON connected to the mainboard and the panel the LED3 is not turning on too and I have no sound and no picture just backlights. from where can I start to debug the issue?...Leave a comment:

Samsung UE55H8000SZ with TCON BN41-02112A
Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele
