Thank you all for your messages.
I've ordered the LEDs, I'll proceed with the operation as soon as I receive them and will keep you updated here.

Philips 55PUS6804/12 turn on & off (probably backlight issue)
Hello everyone,
First of all, please excuse me as I'm quite new to this field.
I have a Philips 55PUS6804/12 TV. It turns on and off instantly (backlight flash). I personally think it's a backlight issue (faulty LEDs). Could you help me confirm my diagnosis?
I've checked and the T-CON seems to be fine. I disconnected one ribbon cable at a time at the bottom, but the problem persists.
The Ambilight works perfectly and stays on.
No sounds.
Thanks in advance. -

Re: Samsung UE50NU7020W TV Stuck on Smart TV Logo with No Display
Yes, I disconnect the wifi / BT from the board and it is the same thing.
I will check about a new motherboard and replace it.
Thank for your help !...Leave a comment:

Ok thank I will check.
Alright, just for your information, a few weeks ago, I tried it, and the TV worked (just one time!), but it was extremely slow. Do you think if I replace the motherboard, the TV will work normally again?
Thank you.Leave a comment:

Here are the photos without the heat sink.
Feel free to ask if you need more photos.
Is it really effective with the fridge? How long should I put the board in the fridge, and how long should I wait before trying again?...Leave a comment:

Here are the screen photos.
When I plug it in, and one second after.
In the second photo, the backlight is on. But nothing is displayed. No sound either....Leave a comment:

Indeed, there is no T-CON; I was simply referring to the two ribbons connected to the motherboard
Here are the photos.
That's the only board of the tv.
In the photo, the speakers and wifi board are removed....Last edited by ovrax; 11-01-2023, 07:49 AM.Leave a comment:

Samsung UE50NU7020W TV Stuck on Smart TV Logo with No Display
Hello everyone!
I have a Samsung UE50NU7020W TV with an issue.
When I plug it in and turn it on, it displays the "Samsung Smart TV" logo, the logo disappears, and it doesn't respond, no reaction at all.
The backlight remains on, but I can't do anything.
I've tried unplugging the ribbon cables from the T-con board one by one, but the problem remains the same.
Any ideas? I haven't found a similar issue on the forum.
Thank you!
