Re: ps50c77hdx/xec
ok i found it the culprit was the 7815 regulator. testing good outside of the circuit but acting weirdly in circuit.. the set back in working order thanks guys for the help

Re: ps50c77hdx/xec
now there's a 50 ohms resistor to ps_on and still no go. 1 got 1.041V on the cold side of the optocoupler. at the pnp transistor between ICQ805 15v and the opto it got 20V on the Emittor and the Base via a resistor then another resistor going to the opto. i have nothing on The Collector/ICQ805 input at 0V. what should I check next?? thanks

Re: ps50c77hdx/xec
i have nearly the exact problem with a bn44-00162 i have no 15V at icq805 output and nothing at the input i'ved track the voltage down to the qc803 pnp transistor it got around 20v at the emitter coming from the tb801/ viper22 area
the transistor test good the base of the transistor seems to come from pcq802 opto. i'm stuck there for the moment. should i check on the cold side of the opto or stay on hot side?
for the ps_on i'm using a resistor under 1k
i got my 5v standby and it's stable.
i replace the cb816 22uf 450v ...

Re: 50 Samsung (Hp-t5054) Completely Dead PSU
sorry to get this topic back from dead I have a similar problem with a 50 inch here but I have the 5v standby i changed the 22uf 450V in case of a bad one. i do read between 3.3V and .244V on the PS-ON pin of CN801 i dont have any red led on the power button on the front of the tv i tried to force it to start grounding the ps-on pin no change i do have 21.35V at cb813. What you recommend next to check?

Re: Samsung Syncmaster 245BW
similar problem here with a 245bw for now no 24v no 5.3v rb805 reads open i'm digging in it for now to find something else burned qm802 reads good.
