Hello, I have a similar problem with led1905. I saved my memory with a batch
from manta led3204 HK-T.RT2957P61 board, TV works but the image is inverted by 180 degrees,
and the keyboard has swapped functions. Please, if someone has a charge for manta led1905
HK-T.RT2957E01 motherboard for sharing,
or sending an e-mail> janusz4386(_at_)wp.pl <
very urgent, best regards janusz4387.
