Hello
I have a Samsung ps50q91h 50" Plasma from 2007, it just does a clicking sound, trying to boot up.
I've already replaced the capacitors, one was leaking but not buldged and the others were a little bit buldged.
Still the same problem, please see this video with this problem, the noise it seems to come from those 2 blue components or the black ones.

Re: Samsung LE32A336J1N - Standby and nothing else
So what can we do next? I'm running out of options, unfortunately, and i really need to get this TV fixed. -
Re: Samsung LE32A336J1N - Standby and nothing else
Well that's the reading of my multimeter.
It's a pretty cheap one, and since the voltage is changing so fast it may be giving incorrect readings?Leave a comment:

I've tested it, since there are 3 pins called 13V Main, i tested one of them.
The behavior is similar to the Power ON/OFF pin, when i hear a click, the voltages goes to ~11V and then it drops to ~2V, repeating itself in every click +/- 2 seconds apart.Leave a comment:

Re: Samsung LE32A336J1N - Standby and nothing else
I've tested what tom66 suggested, i couldn't found a pin PS ON or PSON but i found "Power ON/OFF" i guess that was it.
I noticed something, each time i ear a click the voltage rises to ~4V then drops to 0V.
Each click are 2 seconds apart, more or less.
Can you explain what pins you want me to test it, selldoor?
Please check the attached picture so you can see the pins....Leave a comment:

Re: Samsung LE32A336J1N - Standby and nothing else
Okay, I've done it, and i get the same 5.13V as before. Even if i try to press the on button of the TV, nothing changes 5.13/5.14V.
What can we conclude from this?
So let's recap, with only the power supply i get 5.14V, when i connect the power supply to all the other components, i get 5.13V.
Also please bear in mind the clicking noise i noticed and reported on the first post.
Thanks guys, your help has been precious.Last edited by Neverzinho; 07-11-2014, 01:48 PM.Leave a comment:

Re: Samsung LE32A336J1N - Standby and nothing else
Can you please elaborate on how can i have it connected to the mainboard and get a reading with a multimeter? I was using the solder joints on the underside of the power supply, if you connect everything as it's suppose to be, i can't access the underside of the power supply.
Thanks for your support guys.Last edited by Neverzinho; 07-11-2014, 12:06 PM.Leave a comment:

Re: Samsung LE32A336J1N - Standby and nothing else
Okay, I've done some further testing, placing a red probe on the STB5.3V pin and the black probe on GRD, and the reading is 5.14V steady, with only the power supply board not even connected to the TV.Leave a comment:

Re: Samsung LE32A336J1N - Standby and nothing else
Thank you budm, I eventually found out the connector, when looking closely to the board.
But i still can't get the reading, i tried without the ribbon cable and with a multimeter on pin 7 counting from top left, where it says it gives 5.3V and i get nothing, but I'm not sure I'm placing the red and black probes on the right spot.
One thing that happened is when i plug the power cord without the ribbon cable, the backlight turned on, although no picture or menus could be access.
This may help you guys....Leave a comment:

I'm sorry martino, i've had a hard time understanding what you are asking me.
Where is the connector cm802? Can you place a circle on one of these photos, please?
"Same plug,ps-on,whats the voltage there and is it stable? (might have to try and turn tv on to get a reading... )"
What do you mean by this?
I do have a multimeter i can use to test the voltage of the connection, just point me in the right direction and i will give the readings.

Of course, martino.
That picture was taken with my cellphone, I've taken better pictures with a real camera, please see the attached pictures.
I really appreciate your help, and thank you.
If you need any more information or pictures, just ask....Leave a comment:

Samsung LE32A336J1N - Standby and nothing else
Hello,
My Samsung LE32A336J1N LCD TV, just stays on Standby, doesn't turn on.
I have basic solder and components knowledge but i'm no expert by any means.
I've checked the capacitors, and i see no budge or leaked ones.
What I've noticed is a faint clicking noise from the power supply, and i think it's coming from one or maybe from both, the component marked on the attached picture.
What can it be? How can i diagnose it any further?
Do you guys have any suggestion?
Regards.... -
