Hello,
imac 27 late 2015
lcd display t-con board model 6870S-2047A
Want to repair t-con board
display has no screen, but backlight is on, it communicates with mainboard, all diag leds on.
all ribon connections are without damage
mainboard functions without problem. connected an other display and there is a picture...
so i investigate t-con board and all capacitators for shorts and blown fuses
can´t find any fuses...???
so there are many capacitators that seems shorted...... -
sometimes it can boot normally and sometimes cant turn on at all...i actually dont know where to start for diagnos...already replace power supply but problem still persist....i check power button with buzzer and it still in good condition...when cannot turn on, only 1LED shows....i try using tweezer to jumper power button but also not working....need to rest imac for about 2-3 hours then it will boot normally
here i attach schematic and boardview
