Morning Guys,

Thanks Diif for the files, i tried the U10 file but no joy I'm afraid
Here are my findings when trying different flash dumps

Toshiba 40L3453DB U10 Dump Mine, must be Faulty
No lights-no response from remote or side buttons

Toshiba 40L5435DG Dump Flashed
MB9x_Faz3_V362H_Core bin file
Flashing Green Light
unplug connect usb press and hold ok on RC, get a green solid light, release ok button after 10 seconds and light just stays solid green
turn off and back on just get red/green blinking light, black screen

40L3453DB bin file
Same as above

17MB95 full v3.6.6n bin file
Same as above

17MB95 full v2.2.4t bin file
Same as above

UPG02
Same as above

Toshiba_40L1333DG_U10_25L1606 bin file flashed
Toshiba 40L3433DG bin file flashed

I think one or 2 of these two i got a solid red light when unplugging connect usb press ok on RC plus black screen, if i turned off and on again with ok on RC i get red/green blinking light

Toshiba U10=25L1606E bin file flashed, the one Diif uploaded
unplug connect usb press ok on RC, get a no light, release ok button after 10 seconds and still get no light
turn off and on without holding ok button on RC just get red/green blinking light black screen
I also trying with pressing input button the the side, no idea if that's the button you are suppose to press as i jus got red/green blinking light when trying this on all the above

I don't know what else to try, i might but another main board but just concerned it might not fix it

well i cant follow because now became many files..
i took yours dump file and compared it with diif file.. both are same version.. yours dump one had one pause boot section was corrupted, i did rewrite it with hex. try flashed it, and dont do any more than plug in wall and turn on.. let see what you will have.

Re: TOSHIBA 40L3453DB red-green blinking light

did this TV had history.. or you was not the owner of it before it become defect !!
i just confused why after all these U10 Files you have different results with it..

my previous file of repair i dont think it will bring any to you because of the compare was only at empty data.. see photo..... so please try this 3 files.. just flash and test them on the tv .. let see what you have at each version of this bootloader. LED indicator.. and screen back light... if one brought solid red STB light, turn it on from RC or from side panel of the set.

Re: TOSHIBA 40L3453DB red-green blinking light

Hi,

I tried all 4 files you posted and just turned tv on that's all and got the following results
Toshiba 40L3453DB U10 Dump_repaired
No lights no screen, nothing

FINLUX__MX25L1606E
flashing green light only, no screen back light

MX25L1606E_U10

Polaroid SPI

Re: TOSHIBA 40L3453DB red-green blinking light

flashing green light only, no screen back light.

then just flash diif file and power it on.. let see... it sound to me we have some issue related with NAND or BGA... but we can by try to be sure of the issue..
U11 can you show me where it located... as diif package include it ?

Flashed the file Diif posted(Toshiba U10=25L1606E bin)
Turn on without holding ok button on RC just get red/green blinking, no screen back light

Then if i try with a flash file on the usb and unplug connect usb press ok on RC, get no light, release ok button after 10 seconds and still get no light

Attached is pictures of the location of the U11 chip on the underside of the board

Re: TOSHIBA 40L3453DB red-green blinking light

please dump U11 and upload it here... after you are sure have clean dump.. over write it by flashing diif file

how big the usb drive you are using and at which format ?

[Diah]

Re: TOSHIBA 40L3453DB red-green blinking light

after you finish with U11, take this file and put it on the usb drive no larger than 2Gb FAT32 with the firmware i linked to you from mega download... rename it to mb90_en.bin .. insert the drive at tv. press ok on rc and plug it in wall.. 5 seconds enough... leave it as much it need time.

What do i set the software to to read U11?

I have been using 16gb fat32 and two others which are 4gb fat32 sticks

I have a 1gb stick, will that be ok?

1Gb very fine if you have less will be more fine

the software didn't recognized it and read it at auto?

Re: TOSHIBA 40L3453DB red-green blinking light

try
Manu ------WINBOND

I read it twice but had it set to this W25Q80VB, as that what it says on the chip see attached picture and files

I will try again on the other setting

Re: TOSHIBA 40L3453DB red-green blinking light

flash it with diif file

[Fergal22]

Re: TOSHIBA 40L3453DB red-green blinking light

flash it with diif file

Keep getting this error

[Diah]

Re: TOSHIBA 40L3453DB red-green blinking light

this error maybe because flashing while the chip on board. some need to be out of circuit to flashing or could be the dump was taken with other programmer more pro than CH314. also just consider the software of this CH314 are simple one.. some time need to restart it & clean Temp. ... however after searching yours boards service manual , this U11 are for T2 DEMOD. assigned to U17. so ignore it right now... and try my post #70 if this wont help... sorry i am out of any other idea to replace the boards.

I doubt it will work now as when i tried to write to U11 on auto, it erased it first then failed on the writing part so the chip s blank
I will try post 70 if that don't work i will buy another mainboard for it
