Sasmsung UN660FH6003F question

I have a Samsung UN60FH6003F. Last week it started shutting off like there is a power failure (no melody plays) and after a bit it will power back on ( with melody). I did some research and came upon the capacitor issue with Samsung TV's. I found a replacement power board and installed it but TV is doing the exact same issue. I have checked all the capacitors and none of them are bulging or leaking on either board.

I am lost and would love to get a new opinion on this as I am totally stumped.

When unsure what board or part.

An old tech shared this advice. "Replace the cheapest part first."

The capacitor issue is more about what happens on cold starting, your issue points to some other issue.

Which should be next

I have no idea what I should check next I contacted Samsung and their advanced support team is supposed to contact me in 1 to 2 days.

I just wish I could figure out what is wrong so I could fix it. It is gradually getting worse and doing this more every day.

The symptom

Is not what you noted for caps. It's more like a chip or board has become heat sensitive. Let's ask a simple tech thing. Did you get out the canned air and make the system dust free?

totally dust free

In reply to: The symptom

Yes I completely cleaned out the back. I even removed the panel to make sure the dust was gone.

While board changes are next.

In reply to: totally dust free

Heatsink compound replacement might help, there's a simple test. Point a fan at the unit (vent area, usually bottom) and see if the time changes till it shuts down.
