Hello,
This set is dead no power but i have all voltage like 32v and stanby. The power Eax69009201/ main board Eax66785401(ver1.6)
FR4-2L PTH 1.6
2016.05.26 . I think the problem is from main board i have tested with another board and set worked. Can anyone help me with solution on how to fix the board. If possible service manual. Like i found out this main borad is also used on models like LHD645 and LHD600

no way to repair mainboards. the start firmware saved on cpu. i couldn't find any way to repair it. just replace mainboards.. but i used to replace upgraded motherboards with more in option and connectivity.
