Re: no standby light appeared - samsung tv with psu board bn44-0060B

thanks sir budm.. so my mission is to resolder the transformer legs. check A5v, and the rest of cnm8 connector and also on the remote side .
i have to check temp of mainboard processor and also check if there is a capacitor or component connected between the mainboard and the a5v . check also the ovp of slc1012. check regulator of the boards.Take some pictures
and have a bottle of beer

hoping that there's no shorted diode connected to the mosfet

Re: no standby light appeared - samsung tv with psu board bn44-0060B

yesterday before I put back the connectors on the psu , I measured D904 which is parallel to two parallel resistor of 4.7ohms(theoretically 4.7/2=2.35ohms but measured 2.6ohms) thereby,it will have a total resistance of 2.6ohms. So, total resistance <=2.6 <diode resistance. diode test fwd and reverse (in-circuit) is 0.0001v.
TV works again.. standby light appeared but my kids wanted to watch tv and there's nothing I can do to check further for sure it will be only good for 1 or 2 days...

Re: no standby light appeared - samsung tv with psu board bn44-0060B



this diode is connected in parallel with two parallel resistor of 4.7ohms, so 4.7/2 will be 2.35, considering the fwd voltage of d904 is 0.5v and its rating is 40v ,2amp on datasheet .however its diode resistance(dr) is not linear, if
I will use 2amp then theoretically 0.5v/2 = 0.25 .If they will be connected together in parallel it will have an output [B] total resistance < dr < 2.35[/B]

i have to figure it out again if I measured 200ohms on this connection.Re: no...

the tv still works if I dettached those connectors on the psu board and then reconnect it for about 2 days wherein the standby light will appear again and tv works normally but unfortunately after 2 days of using it ,standby light doesn't show again.This is actually a recurring problem.
However, i already replaced out of tolerance capacitors, checked resistors but i found something unusual when I diode checked(D904 ) with part no.SR204 Shottkey 2A 40V. My reading shows .000001v on both sides of the diode for in--circuit diode test. however,there's a resistance if I checked it and...
