Re: Samsung LN32A330J1D Problems
[SIZE="4"]Not sure why this thread died on the vine, but nevertheless I have a new problem. I decided to just purchase replacement boards for both the PSU and the MB. The replacement PSU is identical in every way. However, the MB, while having SOME of the same numbers on the board and very similar, is NOT identical. I'd like some advice on whether or not the replacement board is usable in this TV.
Here is a picture of the two boards side by side:
The original board is on the right. Notice the circled areas....Leave a comment:

Re: Samsung LN32A330J1D Problems
There are two "lights" that come on when the power cord is plugged in. One is the red LED in the on-chassis power button located bottom center of the front of the unit. The other is also red. It can be seen from the rear of the unit only. It is inside the black plastic connector for the "Digital Audio Out (Optical)" connection. It is the connector that is farthest left of the 15-pin D connector on the MB picture.
I turned all of the lights in the room out and cycled the on-chassis power button. The only light that...Leave a comment:

Re: Samsung LN32A330J1D Problems
Just read your edit of post #12. There is a lot more clear now.
There is no response from the TV when using either the remote or the on-chassis power button. There is no change in the voltage on connector to the MB. Therefore, I assume that there is "at least one stuck signal problem".
I appreciate - from a philosophical and practical perspective - the step-wise walk through the troubleshooting. It is the 'right' (smart) way to troubleshoot. However, it's been a long time since I was up to my elbows in a piece...Last edited by gitano; 10-25-2015, 01:13 AM.Leave a comment:

Re: Samsung LN32A330J1D Problems
I didn't note your CN802 and CN803. I am getting 24VDC on the correct pins. I am NOT getting 380 VDC [I]anywhere[/I] on the board: 330VDC is the measurement.
I get the following values for pins 11 through 14 on CN803:
11 - "A/D" = 3.48VDC
[COLOR="Red"][B]12 - "B/L" = 0.11VDC[/B][/COLOR]
13 - "P/D" = 4.44VDC
14 - GND = 0.0
Pins 1 through 5 have 24 VDC, and pins 6 through 10 are ground.

Re: Samsung LN32A330J1D Problems
"No" to most of your questions.
Specifically:
There was no voltage specified. The value measured was 3.93VDC.
I have no way to "activate" this switch other than to plug the ribbon cable in. With the cable connected between the PSU and the MB, the voltage value is 3.93VDC.
There are no pins designated with voltage values of 24.
Here is a picture of the plug and the nominal voltage values associated with each pin:
Pin 1 is on the left and toward the top...Last edited by gitano; 10-24-2015, 09:49 PM.Leave a comment:

Re: Samsung LN32A330J1D Problems
With the MB cable connected and line power available, all of the pins read the correct nominal values. Clearly a switched PS.

Re: Samsung LN32A330J1D Problems
We'll see what "he" can do.
By the way: "Hit the power switch" does nothing. Neither with the remote nor manually with the on-chassis power button.

Correct.
Thanks, that's what I thought.
[B][COLOR="Red"]Are any other diagnositics necessary?[/COLOR][/B]

Re: Samsung LN32A330J1D Problems
With regard to posting images:
I read here the following here: [url]https://www.badcaps.net/forum/member.php?u=18381[/url]
I cannot tell if retiredcaps is referring to images in the above admonition. Most sites I use PREFER that users use an off-site image server and post a link to that image. If retiredcaps is in fact referring to images posted here, I assume the 'management' wants me load my images to their server.

If by "backlight" you mean the little red light in the on-chassis power button: "No".

Samsung LN32A330J1D Problems
I have a Samsung LN32A330J1D, Model Code "xza". The power supply unit model is BN44-00191A. The Main Board (MB hereafter), has a sticker with the following number on it: BN97-02111F. However, the board is stenciled with:
Jade Board
BN41-00965A
2008.01.14
Here are pictures. First the MB's labeling:
Next, the PSU whole:
The TV will not power on but the red light in the on-chassis power button is on/lit when the unit it plugged in.
Here are the events I think are relevant that preceded the failure:...Last edited by gitano; 10-24-2015, 06:28 PM. -
Re: New Members - please post your introductions here
Fulfilling the "at least one post" requirement. Electronically educated by the USN and college.
I have a broken TV and need help troubleshooting and getting replacement parts.
Thanks,
