Наличие схемы: LG OK75 service Manual
Replaced IC501 -MLC3730S with new one the effect was the same no power on no display reprogrammed the two memories no signs of life ,
The 1v2 ,3.3 ,5v,12v OK but the MLC doesn`t start power on to other chips so switches are turned off,and the communication of spi looks verry strange on osciloscope some idea where to dig ?
