What control have you over the video Settings?

Re: TOSHIBA 48L1433DG no display

Hy,

There is no way to change type of panel, only basic configurations for input, sound, video but not resolution or other.

Having copied the original file mboot.bin, I can flash my TV by USB and modify part of file "usb_auto_update_A1.txt"

# <- this is for comment / total file size must be less than 4KB

#mboot
#For pure mboot.bin upgrade, use below part
#fatload usb 0:1 80400000 mboot.bin
#spi_wrc 0x80400000 0x00000000 0x0120000

#For mboot_spi.bin (padded to 2MB, added logo, edid/ddr etc) upgrade, use below part
fatload usb 0:1 80400000 mboot.bin
spi_wrc 0x80400000 0x00000000 0x0200000


What I miss is the full firmware because every time I have the wrong panel load

Re: TOSHIBA 48L1433DG no display

Not a panel fault. The panel configuration is wrong. Wrong firmware or panel.bin file.

If your TV does not turn on and the LED blinks red and green alternately, only USB firmware will help you.

1. Press and hold the OK button ON THE REMOTE CONTROL.
2. Plug the TV into 220v
3. The STBY LED flashes slowly and then quickly.
4. When it flashes quickly, release the OK button and wait for it to finish.
It may take up to 5 minutes.
