Hi All
been a while but just got a Phillips 42PF7521D
owner said it just wouldn't power on one day
looked inside no obvious caps on PS but did find one on the zsus - c5040 100uf 50v
replaced that but still the same issue
when you plug it in you get the 2 clicks and LED's on PS light up then 4 seconds later as the main board LED's are flashing it shuts down
then i get 3 flashes on the sub board on the top left of the PS pic
its strange though as the LED on the front just stays green the whole time as if its on no red LED at all
If i isolate the zsus the PS stays up, my question is does that mean its a zsus fault or when it trys to pull power thats when the PS fails ?
there are 2 other caps on the zsus that look suspect but i will have to raid the spares bin as i dont have any 68uf 63v
