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"
[I]# <- 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...Leave a comment:

Re: TOSHIBA 48L1433DG no display
I received my mainboard Vestel 17MB95S-1, second and.
I copy and saved the bin file of MX25L1606E whis CH341A tool.
Unfortunately, the used board is KO,
no start TV.
I recopy the MX25L1606E bin file into old mainboard and tested.
The TV start correctly and I have sreen now.
But the picture is bad.
I suppose the panel detect is not good. see the picture
What is the factory reset mode ?

Topic is : Toshiba 48L3433DG wsad SPI
It's for same panel VES480UNVS-M01
Problem : I have not point enough to download this.

Hy,
Panel is : VESTEL VES480UVS-M01
At the begenning, my TV don't start, blinking led red/green (0.5seconde), no action with remote.
I read serial eeprom with CH341A. and compare with mboot.bin (firmware 10082828_27092518_40D1333B, 3 files), 50% of data are corrupt.
I copy mboot.bin in eeprom MX25L1606E.
After, I copy in USB flash mb90_en.bin with usb_auto_update_A1.txt
On start TV press ok and boot in USB flash is ok.
At end, remote controle is ok, backlignt is ok,...Leave a comment:

Re: TOSHIBA 48L1433DG no display
Thanks dick_barton,
It's seems to me that baudrate is 115200.
I use "termite" software
If I change baudrate 9600 to 115200, is the same problem.Leave a comment:
