Updating Firmware on Toshiba 65X9863DB

[merravid]

Hi,

I have a flashing green/red light on this model which then goes to fixed red. No display whatsoever. Voltages at the power supply look OK, so I'm guessing it is a motherboard/firmware issue.

I've downloaded the firmware for the model and serial number which contains three files:

mb130_en_bin.gz
mb130_PM51_connected.bin
mb130_RomBoot.bin
usb_auto_update_g10.txt

Looking at the script file, it look like it wants mb130_en_bin.bin, which is inside the .gz, so I'm guessing I need to extract that before trying to flash? The RomBoot file is also named differently, do I rename this?

Just want to make double sure - don't want to risk bricking the mobo (if it's not already).

Also, someone on some other thread, suggested commenting out the mboot part. Do you suggest I do that? What about the PM.bin part?

Thanks.
