Just reporting back in.

I replaced the power supply board on the Samsung 51" F8500, and it works like a charm. Easy do it yourself project.


I know it's been 2 months since I posted about fixing the unit, but summer is my busy season. Once I got around to it last week, took little time to remove back and board, ship, recieve and install > reinstall back panel.

Ive been using a Panasonic 50" ST60 in it's place. The Samsung is much better during the day and the Panasonic is noticeably better during night. But they are both great units. (Wish I had the 55" ST60)

$75 shipped, for the board. I got one off eBay from a guy in Haymarket, Virginia. Oleg was his name. Fast turnaround.

I wonder if I should get a spare power supply for the future before they disappear.

That doesn't sound like the problem in this case so it might be worth paying to have Samsung send a tech out to troubleshoot the issue and come up with a recommended solution.
So if my set won't come back on immediately after being turned off after its been on for several hours, it the Y-Sustain board? If I let it cool down, it will restart.

Not necessarily, if your TV is not powering on at all to me it suggests an issue with either the power supply board or the main logic board (there are only 4 boards total in this tv). When the issue is with the Y-Sustain the TV still powers on, it just doesn't produce a picture. The following video shows the typical symptoms of a failed Y-Sustain board. Those symptoms tend to initially start of intermittently, often after an accidental power off, and becomes more frequent as the capacitors degrade. Replacing the 3 capacitors as described in the previously linked thread resolves the Y-Sustain issue.

Hello all. My F8500 developed a weird little quirk at some point in the last few days and I'm hoping it's not the beginning of something more serious. The Samsung logo and the four little charm icons or whatever you want to call them suddenly appear when I turn the TV on - but they never have before. A trip into the menu reveals the boot logo setting somehow turned itself on, so I turned it off again. However, the four little icons still appear briefly on screen when it starts up even if the Samsung logo doesn't, and no matter what the boot logo setting switches back to "On" again.

Can anybody shed any insight into what this could mean, how it happened and how I get it to stop?

This popped up after the most recent firmware. Appears that Samsung is forcing the boot logo since, as you discovered, you can no longer disable it in the menu. You may be able to disable it in the service menu but I don't know the setting, not a big enough issue for me to investigate it.

Oh. Alright then. That's weird, but if it's not something I did or if something isn't breaking down, I supposed I don't care.
