SOURCE: Samsung TV won't turn on- trying to fix it. A challenging problem

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.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.

How is the power supply module? Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I have a 42" Samsung


This clacking and clicking noise could have been coming from a capacitor going bad in the tv. If this is the case where the tv will not turn back on, I would suggest calling samsung to try to get a replacement or get the tv serviced. Trying to replace bad capacitors can be a tedious job and requires knowledge of soldering small components. This may also void your warranty if you still have coverage.

Standby light flashes and TV won't turn on. Have to unplug it and wait for a bit then plug it back in and TV turns on. Quite a delay though. Then after TV is turned off, standby light starts...


seems like a power supply problem inside the tv and when the transformer gets warm it is giving you problems you might have to get a tech seviceman to come out and have a look at it as it is not a job you should do yourself when it comes to replacing the power supply hope all goes well

PS3 shuts off right as its turned on


Hi, this is heat related and, this issue may have damaged your power supply board. if the red lights continue to flash after you have unplugged this unit for 5 minutes, this will confirm power board failure and, you will need to replace this circuit board.

You can purchase a replacement power supply unit at this link below and i also advise to purchase a cooling adapter for your system as well. this will prevent this form happening again in the future.
