Hello mga ka tech. Sana makatulong. After buhayin ang unit na y9 2019
Found no network, wifi ang Blutooth.
First step. Check voltage by section. Found good.
2nd step. For signal. Remove pa and reball. Upon removing my mga corrossion na sa ilalim ng ic. IMG_20231017_090114.jpg
Third step pinasayaw ko lahat ng pyesa ng signal pati RF ic.
Then reball PA and install. IMG_20231017_103255.jpg

Final step reball ic and install.IMG_20231018_115647.jpg
