UE40C6800 -> Board BN41-01444B -> Changed "Dnie"-BGA, nothing working anymore
Posted: Wed Oct 05, 2016 8:48 am
Hello Forum,
this is my first post, so I hope doing it all correctly and you understand my problem.
I have a Samsung UE40C6800 TV-Set, which has the known Problem with the "Dnie"-BGA (Mstar-BGA) with broken/interrupted solderballs.
Board-Type: BN41-01444B.
The Picture was corrupted, but the TV was working so far.
As i got the opportunity to change a bga with a professional bga-station, i ordered a new bga from china, and replaced the old one with that fresh...
Type and writings of that bga are exactly the same... Soldering on the bga-station is completely automatic, so the replacement should be perfect.
But my problem is:
The tv is just power cycling.... No Picture, no light, no sound... Just booting, turning off, booting again...
So my question: is it possible, that this BGA must be preprogrammed or flashed before using?
How, when needed, can this be done? Are there Jtag-Pins etc?
Sorry, but i am a very beginner on these tv-Sets...
Thank you for spending your time and trying to help me
Cheers, Tob!
