You have K9F1G08U0D, look carefully.

yes sorry my previous link was for a different chip, thanks for the reminder.
Is this one correct ?

I can't do that but there are chips that come already programmed. I just have to find the correct one for my tv I guess.
For example this one, do you know how I can confirm if it is fine for my tv please?

There's not much point buying an empty chip, it needs fresh contents programming in first.

I am going to try then, since the tv will go to trash anyways nothing to lose...

On ebay I find lots of K9GAG08U0E SCB0, while mine is a K9GAG08U0E SIB0. Is it fine ?

I would think it's failed physically with to many bad blocks.
You have tried the only way to repair it without replacing it.

This one?
If it's the one, I think I won't be able to solder a new one it require too much precision. I can solder mosfets or like, but this kind of chips require an equipment I don't have (microscope...). Isn't there a way to program it without removing it?

Just above the scart socket.

Rebooting after the logo suggests faulty NAND.

thanks, I read some threads about this too so maybe it's the case yes.
Do you know what this nand looks like on my motherboard please, or maybe its reference? so I can try to find one online. Thank you

Yes I tried this too. The tv bypasses everything and starts as soon as it is plugged

Did you try unplugging then holding power button while plugging tv back in?

The tv restarts over and over again as if there where no usb drive plugged. I think the usb drive is not even read by the tv, nothing happens.

So update failed or did update and not fixed the problem?

Hello,

My Philips TV 40PFL3148H/12 keeps restarting as soon as the Philips logo is displayed, as soon as I plug it. The remote doesnt have any effect on it anymore, plus no red light on the tv panel as usual.

After contacting their support, they sent me a file to update the firmware from usb but without success (8gb 2.0 drive formatted in fat32).
Then they told me that it was a hardware problem.

Here is a video of the problem : https://streamable.com/8ixf1u

Thanks for your help
