Hi All

I have this tv and if I measure the various coils i get 3.3v, 5v, 12v and a 1v.
But i have no Standby Light and no reaction from the switch.

If I measure the the pins going to the rx and switch I Get 5v and a few other pins give 3.3v

Where do I start looking with something like this, could it be the processor. I do feel that its slightly warm. not hot at all.

Thanks
Gav...

Hi i have a 32in with a TP.VST59S.PB702 Board.
I get all voltages 5v, 3.3 and 12v on the 12v upgrade and 22v on the led connector, and 3.3 on power switch, but no response when trying to power on.

If I test the power on I get a voltage drop to zero but no reaction....

Re: Samsung UA40D5000PR Pulsing output voltages

I have unplugged and retried a few times with the main board and backlights in and out.
I get different readings, with everything in i dont here any noise from the mosfet area and solid 300 on the lower mosfet but nothing on the top one.
then i also only get pulsing A5V. nothing else.
With all pugs removed i get pulsing on all measurements on the connector to the main board. I also get pulsing on the led connector.

Ill try warming up the caps and see if get any difference.
I dont see any bad joints...

Hi Guys

I Have this Samsung smart tv that needs repair.
with everything connected i get pulsing A5V at the PSU connector. if i unplug the main board then all voltages pulse on the output connector.
I dont get any voltage on the LED connector.
there is also an audible click around the mosfet marked below
The connector to the Buttons all voltages pulse (3v)

I have searched and found a similar problem but there was a stable 14v, but was also not repaired.

I checked and replaced the mosfets with no effect.
Any ideas where...
