Philips TV 40PFL3148H/12 keeps restarting on the logo

[alfonzzo]

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

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

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.

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

Re: Philips TV 40PFL3148H/12 keeps restarting on the logo

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

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

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?

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

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 ?

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

You have K9F1G08U0D, look carefully.

Re: Philips TV 40PFL3148H/12 keeps restarting on the logo

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?

Try different USB flash drives, but old 1-2 Gb ones are better, not all flash drives will be updated.

No, that's for a Samsung TV.

Re: Philips TV 40PFL3148H/12 keeps restarting on the logo

seller says "all codes BN94-0xxxx"
How can I find this code?

Well I will buy a 1gb one and retry, but honnestly I already tried with 3 usb sticks ( 8/32/128gb) and nothing happened.
