Yes, indeed!

nomoresonys: I was not sure which way would be best. After lotas pointed out why moving IC1603 would be a solution I will try replacing it.

I guess there is no other way to flash that IC with different T-CON data (e.g. via USB stick)? I have done so before with a philips tv.

And lotas: I agree with your observation. Board A does not show any signs of burnt components and the whole TV is quite dirty and might have been in a kitchen with smokers....

Hi there,

I am not new to this forum but most of the time inactive so I must have missed to introduce myself when I joined a few years back.

While searching for an affordable TV some years ago some offered a TV for free which did not display a good picture. Searching for clues I found out it could have been a faulty T-CON. I replaced it and voilà: The TV worked!
It has become a passion to try to repair TVs and electronics in general....

@lotas: thank you for pointing out the differences of the boards which may explain why the image on board B is distorted. I have added a picture of board B (distorted). Please notice the panel itself shows three vertical lines which is a fault of the panel.
The distorted picture (board B) has an offset to the bottom and displays many more vertical lines
I did take over the service panel type from board A (which is the original board for that panel) and set it in board B without noticeable change.

I could try to move the resistor from position 3 (distorted) to position...

I have two Boards BN41-02568B for a UE55MU6179 of which one does produce a good picture (Board A) but can not save its configuration (even a factory reset will not work) and one board which produces a distorted picture (Board B). Learning from here the IC1604 saves the configuration of such a TV.

Before replacing the IC1604 from Board B to Board A - would that actually solve the problem from Board A not being able to store its configuration or could there be something else wrong with writing to the flashrom? Is it even the right chip to replace or should I look out for a different...
