I got it fixed with a USB bootloader & firmware update.

This ZIP file TPM191E_101.2.178.0_upgrade_loader.zip contains a file named upgrade_loader.pkg
Just put it on a USB stick that is formatted MRB FAT32 clusters 64byte.
Insert into the Black USB 2 (500mA) port on the TV and hold down power button while plugin the power plug.
Now you see on the screen that a update is in progress and let go the power button, this takes about 15 to 20 minutes to finish.
When the update is done the TV switch itself off and you have to power it on by power button on the TV,...

Thanks !

Do you happen to know if this restore software is available for download on the net somewhere ?...

Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.

It does power up when pressing the power button.

I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.

Could this be an PSU or eMMC issue ?
