Hello my grandmother Samsung ue40eh5000 is died even no stand by light. After disassembly I found one busted capacitator (CM852 47µF 200v) in the power board. I replaced it but still no standby light.
Samsung ue40eh5000 no stand by light
- If I disconnect the main board cable from the power board the backlight is light up.
- I measured the right voltages towards a main board 12.75v , 5.2v
- The 2 VAMP kable also have 12.75v
- (I don’t really know what going on the PWM line)
I think the power board is working fine.
I think the mosfets are ok in the main board I measured 3.4v 1.8v ….. and not found a short
What I found towards a switch button (ir, standby light) board instead of 3.3v only has 0.4v
My question is the problem with the main board?
What would be the problem? Where should I look?
Might be better to change the complete board?
