Hi, I have a samsung LCD that keeps making clicking sound and won't turn on. From my research you need to change the capacitors. I have done this and it still won't turn on. Is there anything

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.

SOURCE: Samsung LCD TV doesn't power on, just blinks 5 times

After about 5 years the Samsung LCD televisions backlight fails which prevents the TV from coming on and the powerlight just flickers the backlight can be changed but it is often alot easier and cheaper to buy a new Television

this is common fault the capacitors have blown on main power board you can replace your self if got soldering iron
take back off tv and look for capacitors that have RAISED TOPS they look like little batteries with white line on one side and numbers (e.g 2000mf 25v ) the best way to remember which way they go back is take picture
you can get parts from charles hyde and sons web site (CHS) under general components or at a electronic shop

SOURCE: I have a Samsung LCD model#LN-T5265F and my tv is

Hey, i am now having the same problem as most ppl with the Samsung TVs. I have a LNT-5265F which I bought in 2008 (so only 2yrs old). It now only makes a clicking noise (blank screen). The clicking noise is roughly every 3 secs. Based on research I believe it is the bad capacitors issue. Can someone tell me if the power supply board is still under warranty? Also, what type of capactitors are recommended to buy for replacement? and worst case what is the p/n for a new power supply board for my model?
Also, I watched the videos showing you step by step on how to perform the repair on your own, but little bit confused about the "Hot" vs "cold" on the board? Sorry for all the questions. Thank you!
