Hi all and thanks in advance for any help or insight given. I did research first and did see any previous thread that matched my question.

About 1 year ago when I tried to turn on the TV all it did was make a clicking noise. Research showed that most likely two capacitors were bad. I took the TV apart and discovered, as shown, two capacitors that were swollen. I replaced them myself and the TV started to work just fine again.

Last week I go to turn on the TV and it sounds like it is booting up, clicks, makes the start up Samsung sound and then seems to shut down, only to immediately go through that process, automatically over and over again for about 5 minutes until the TV will start up and play.

My question is, given the TV sets age, what are your thoughts on this apparent rebooting. And secondly, is it worth fixing or will other parts start down the same path and eventually be one thing after another?

When the TV is on, the pictures is great and I notice no other issues.

thanks and kindest regards.

Thanks for the research. I read through them both and one noticeable difference is that the only sound my TV makes is the Samsung factory sound as if it were starting normally. Then it does it over and over for about 5 minutes then comes on. No squealing, no raspyness through the speakers - just rebooting almost as if someone were standing there turning it off and on again and again.

I checked and there does not seem to be any factory updates due to the age.

It just seems to me that there is something specific that must be common among Samsung TV's. I don't want to spend $100.00 and that not work only to do it again. I don't like a trial and error.

Sad part is I paid about $4000.00 for the TV. Sometimes I just wish it would die and the decision making process becomes much clearer...lol

Just don't get Radio shack ones. Panasonic FM or FC series from Digikey.

What does BD stand for? BD809 is on my main board. Plugged it in and BD809 looked like an LED and was smoking. Burnt itself right off the board. As far as I can tell it stand for diode but it looks like a capacitor. So I have 2 of these boards. The best I can figure out it may be part BZX399-C6V2. I will take a picture of the good part when I get a chance.
