Re: Samsung PS-42P4H Plasma Turns on and off clicking
yes, not much info out there on it.
I did find some info today that there might be an updated part number of BN96-00923A. Haven't found much info on that one either.
The price of the power supply is why I was trying to find a way to repair it rather then buy a new board.
I would prefer to fix the board, but if I have to buy the board it won't be too bad. I am only into this TV for a $100. So I won't considered it too bad of deal if I end up getting a working TV for around $250-$300

Also I found the service manual on [url]http://elektrotanya.com[/url]
Here is a link to it on my google docs.

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Thanks PlainBill
Now that we have narrowed it down to the power supply, How do I go about troubleshooting it?
Thanks againLeave a comment:

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Sorry trying hard to give you the info you need. I really appreciate your help.
Thanks for the reminder about the voltages, I have been tearing apart electronics since I was pretty young, and have grabbed the wrong thing a time or two and got bitten. So I am really careful now. : )
The second to the bottom pin on the 9 Pin connector (CN804) is labeled Vg.
Pressing power button does not make difference on any test
Step 2. = 15V
Step 5. X Drivers unplugged = 15V

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Any connector that said 3.4v only had .4
I didn't find any 12v on the power supply board.
But I did find 2 on the board to the left of the power supply board.
There was 0v
I didn't find any connectors marked higher then 12
There are a serval voltages written near the bottom of the power supply ranging from 3.4. 5, 12 14, and 33
but there are no connectors near buy just some bars.
If I unplug the tv and wait a minute, then plug it back it, while...Leave a comment:

What other outputs?
Where would I find them on the board?
I sure wish I could find a service manual for this thing.
Thank youLeave a comment:

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Ok did some more checking.
I think I was checking at the wrong place.
I checked at the bar where the CN842A was writing on the board.
There is not any voltage there.
But I looked around and the connector and realized it said STD-5V.
I couldn't see it with the plug in.
So with the connector plug in I checked the votagle in the connector and there was a solid 5V there.
Thanks

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Thanks Guys
Checked the fuses again all are about .35 ohms.
Couldn't find anymore.
Checked for voltage at the CN842A test point. But there was none.
I tested it using several screws as ground, an RTN point near CN842A and some of the RTN points in a couple of the plugs.
I thought the relay was kicking on and off but, it only clicks on once then shuts off.
Let me know where to head next.
Thanks for the advice

Re: Samsung PS-42P4H Plasma Turns on and off clicking
Wow thanks Gents for the quick reply
I did check all caps for voltage to make sure they were discharged.
Found three fuses removed and checked continuity.
All looked good.
I am not sure where or how to check for standby and secondary voltages?
I have attached several pictures of all of my boards.
Let me know if you need to see more pictures.
Also I have set up a picasa web album that has higher resolution images
Thank you!

Samsung PS-42P4H Plasma Turns on and off clicking
Hello I have a Samsung PS-42P4H1 42" Plasma
Power supply# BN96-01047A (PSC10071J M)
It tries to turn on, but a relay just keeps clicking.
The screen never actually turns on.
I have repaired several computer LCDs before so I am not a complete noob, but I am new to the bigger stuff.
I have the tv apart and searched every board for signs of a blown cap.
But haven't found any leaking or bulging.
I have always been lucky before the culprit capacitor was very obvious.
From my research I am guessing the trouble probably...Last edited by DigitalRambler; 08-06-2010, 09:20 AM.
