Question about Samsung LN-S4051D 40 in. LCD Television
Help needed on fixing a Samsung LCD TV (LN-S4051D). The 1.5 year old TV won’t turn on. There is no picture or sound. When plugged in, a click sound was first heard followed by the red LED light blinking 4 times (next to the power button on the panel). Then the click sound came back again with 4 blinks of the LED light. The whole thing went into a cycle while the power button on the panel and the remote are not functioning.
I did some research and followed the suggestions on a “similar” problem brought on this forum. I replaced the IP board (power board) with a new one. The problem still existed. Then I checked all the capacitors on the PCB board (the main board) and found no blown ones. My question is that what is the real problem of the TV, and if it’s worth to spend another 300 dollars to replace the PCB board. (I already spent over 100 bulks on a new IP board). BTW, the TV cost me 1300 dollars when I bought it. Thank you.
I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

I had the same problem, but found when messing about with the power cord behind the tv it clicked on ( just pull the power cord out slightly & Bingo TV again) reading all these other solutions and the cost people have gone through started getting me worried. Good luck everyone hope this works for you. Never buy a Samsung again, may look nice but thats all...??

Great post. It seems replacing PCB board works for this problem. As I posted on Jul 29, 2008, I replaced the IP board, which is the power board and it didn't work. The IP board I replaced is the small one with electricity gets in.
I guess the Power PCB board you referred to is the larger board with all the HDMI ports and antenna connections. Is that right?
If this is the case, people with this problem should try to replace the PCB main board first. It's very likely to solve the problem. If your TV is still under warranty, call Samsung to fix it.

Thanks for the post - I replaced the IP board BN44-00134A purchased from Encompass for 91.58 plus shipping. It was quite easy to replace and I am so glad I found comments where others had success.
It came on and all seems well. Thanks!
