My Philips TV model no. 26PFL4507/F7 made a click sound and turned off while I was watching a show. I tried the turning it on with and without the remote, but it won't turn on or even make a sound. I opened the back and checked the BA21F0F0102 2 board fuse is not blown. What is the most likely part to fix it?
Get the repair manual and perform the needed diagnostics, I can guess but if that doesn't fix it you are out money and time, I'm out zip.

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.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:

You either have a cold solder joint in your horizontal deflection circuits or your or in your horizontal output circuit. please be careful due to the fly-back transformer still holds power even unplugged until you discharge it.( ground it out). Hope this helps.

OK this is a classic switchmode power supply problem There is a fault either IN the SMPSU, OR in another part of the set, usually a short circuit. The PS, is "Shutting Down" for safety reasons, so as to avoid a possible fire, explosion etc. You really need to have this looked at by a qualified person. before you get any work done, always ensure you get a firm "Quote" before proceeding. This is very common.
