Re: Samsung LA32R81B Not Turning On
Unfortunately meters are not that usefull for checking capacitor.
Does it look oK, not damaged or out of shape in any way.
Could you confirm you still have 378V across the pins of CP803 and what the voltage is on Pin 11 of ICM801
The voltage developed across RM824 is not quite high enough to switch off QM805.
However with the figures given above:-
If the PFC voltage is 378V and you do the calaculations using the resistor network RM819 to RM824 then the voltage across RM824 would be 3.68V more than enough to swith on ZDTM801 which then turns off QM805. Something is not adding up.
