Re: Samsung LN32c450E1D troubleshooting

Hi budm Sorry I took so long. I was away for a few days. I decided to remove the Main Board from the chassis and was surprised to find that the bottom of the board is stained with obvious water marks. I think it is from condensation of the air in the room. There is no sign of water any where else, so I think that the board may have been damaged by the condensed water. I would like to replace the whole Main Board. What do you think?

Re: Samsung LN32c450E1D troubleshooting

I've been searching for a diagram for this Main Board (BN41-01334A) but can't seem to find one. Can you assist me with a copy please. I was only able to find BN44-0039A which does not have the 30 pin connector to the T-Con Board. Thanks.

Hi budm,
Backlights are on but there is no voltage on either side of the T-Con board fuse FP1. This board is situated at the bottom of the TV set, kinda hard to get at, but the fuse itself is visible and easy to take measurements from.

Re: Samsung LN32c450E1D troubleshooting

Okay I disconnected the cable to the T-Con board, there is no difference. I would like to add that with every thing connected properly, and I press the power button on the remote control the following happens:
1. the red power LED flashes 6 times,
2. between the third and fourth flash there is a little melody played and the back lights come on,
3. there is nothing on the screen but it is back-lighted, it stays that way as long as power is on,
4. when power button is pressed to turn it off, the melody is again played...

Re: Samsung LN32c450E1D troubleshooting

I'm sorry to break in, but I can't post a new topic yet, thanks. Where can I find a definition of the codes for Samsung LCD TVs. I have a Samsung LN32C450E1D that flashes 6 times and then nothing. I did the checks of disconnecting the cable from the Main Board to the Power Supply. I got the back lights coming on, and then go off when the plug is reconnected. The following voltages were measured on that plug to chassis ground:
Pin 2 = 5.02v Pin 1 = 12.13v
Pin 4 = 4.87v Pin 3 = 12.16v
Pin 6 = 4.94v Pin 5 = 12.16v
