Phiilps 50PUS6554
Chassis TPM14.6E LA

Hello everybody

I checked the power supply of the TV set which is good , and now it appears clearly to be a software problem.
I could not find any dump for this model, can you help me ?

Thank you and have a nice day.

Thank you Yokoono, I just see now I made a mistake in chassis number, it is actually TPM19.6E LA. I am going to make correction immediately in the post

Thank you Diah, following this link, I could not find this model in the page. I don't know exactly what to download.

Do you need a dump eMMC for a programmer or a service firmware via USB?

[yoritomo]

I may try a USB flash, because it has reaction from power on button, the LED goes off, but if it is flashing only by menu that is not going to work. Sometime a remote control key combination launch the flash, I don't know about this one.
I don't know also if it is possible to try a ISP flash of the EMMC with this board.

[lotas]

Yes, you can also use ISP. Just make a copy of your dump (backup), and then experiment with USB firmware.

[yoritomo]

So it is the way I will do, but I don't have that dump. It may also come simply from the BIOS.

[lotas]

Save your eMMC dump, just in case (since it contains the keys), and then experiment as you wish, so that you can later return everything back. If you need a dump, I'll give it to you.

[yoritomo]

Yes please .Have you both dumps ? where to find it ?

[lotas]

Why are both dumps? Only eMMC suffers here.

[yoritomo]

How can you be sure ? Most of the time I only flash the eeprom BIOS and it works, it is not so often to be the emmc or Nand in trouble. Symptoms are often similar in both cases. In this TV set U409 seems to be the Bios.

[lotas]

You know better, but unfortunately I don’t have BIOS.


Don't confuse the QFU1.1E LA, QFU1.2E LA, QFU2.1E LA chassis, where the bios is (spi flash M25P10 and NAND) and this chassis, where the eMMC is and the boot is from the BOOT1 partition.

Thank you Diah, following this link, I could not find this model in the page. I don't know exactly what to download.

at the link i gave to you search the site after 2019 model yours 6554 one of them... you will find many version of upgrade_loader firmware... only this fit to downgrade or upgrade.

but since yours screen 50 , this size 50 are rubbish over all brands, so disconnect the panel then see if the TV work yours sign will be the Optic Port lit Red

Lotas: is it the post in Remont AUD ? the Dump 2Gb ? Ok I will give it a try and then lets see if working, thanks a lot.

Diah: I found one working link, all other ones are dead in that section, do you think such upgrade file might work in blind ? You are right I should try to disconnect the panel to find any short on it. Thank you
