Samsung LE32R86BD red LED blinks

Question

Hello everyone, like many people, I'm having trouble with my Samsung LE32R86BD TV. It stopped turning on overnight. The only thing that happens is the red LED next to the power button blinks and the blue light strip under the TV is on.
I saw on the forums that there are often mentions of "bulging" capacitors problems, but after disassembling and examining the power board, I don't see any capacitors that seem defective. Do you think I should still replace all the capacitors (there are apparently 7 of them that are usually involved in this kind of failure)?
I’m attaching photos of the board in question and a close-up of the capacitors.
What do you think?
Thank you for your help

Hello
the 6 + 1 small one on the right side of the 1st photo is marked bigger with a blue pencil. Be careful with the voltage; it should have one or more capacitors, I believe, of 15v, to be replaced with the same voltage as the others.
And for the TVs and screens, it's a power supply issue, so the capacitors are often faulty.
I have other small tips, but I would be going off-topic.

Hello
As you saw on the forum, it's better to change all those that are near the heat sink because they don't mix well, and just for your information, if you have electric roller shutters that are starting to have trouble going up, it's the same with a capacitor and it's back to normal
I hope I helped you

If you have any other advice, I’m all ears. The capacitor trick already seems like a good start, even if they don’t appear to be damaged. Having had the same type of issue with my Senseo, just one capacitor and boom, it turns back on! But a TV isn’t like a coffee maker, so don’t hesitate to share your similar problems with me.
Thank you

On the other hand Guluk, initially you advise me to change the capacitors near the heatsinks. Are you referring to the 7 largest ones or should I also change the 5 smaller ones that are located more towards the center of the board? Thank you

Hello, I have exactly the same TV, it has just broken down (the red LED next to the power button is blinking and the blue light strip under the TV is on). It's really the same, I don't see any swollen capacitors. Could you show me in a photo which capacitors I need to change? And did you manage to get yours working? Thank you.

Hello: you have a multimeter, you just need to test the transistors in the primary and the diodes; just one faulty part and the power supply is bad. So in my opinion, you should start there. I looked at the board, I didn't see any swollen capacitors; as for the rest, you can't see the transistors if they are dead. See you later.

Same TV, same issue, I've replaced all the capacitors on the board... the problem persists. The LED blinks 5 times then stops.
What else to do?
Check with a multimeter... okay, but what measurement should I take? And where should I take them?
I'm following the thread... even if I'm a bit late... ;)
