Good evening very kind Lotas, I have a UE49MU6120KXZT TV

BN41-02568A
CY-GM049HGLV1H panel
POWER BN44-00807F
Completely off, disconnecting the mains turns the backlight on regularly.
I read your W25Q40CL but it is completely defective, in fact when reading it it is completely erased, is it possible to restore it somehow?

This thread is now closed. Sorry but it has gotten out of control, there are too many requests being made for models which are totally unrelated to the original thread topic.
If you are requesting firmware please post in the eeprom dump thread or start your own thread if you cannot find a related topic.Comment

First off I am not expert but I do know my way around electronics and have a fairly good grasp on troubleshooting them.
I acquired this tv for free from a neighbor who had a repair man out and diagnosed it having a shorted lcd panel.
