Sony Bravia KDL-70W850B T-CON board / software update issue

[shahnld]

Good Day.

I just replaced tcon on my sony kdl 65xg9505 and getting green amber leds blinking. all voltages are ok according to working sequence.

i downloaded firmware from sony and there is no .pkg fike.. after extracting it gives another file which contains multiple files like inf, payload.bin and 3, 4 other files. i just did that usb but did not worked. anyone knows anything how to do it..?

renaming, in original state nothing helps. any idea's which may help is welcome..

cheers

Try using a 4gb or less drive, Nick knows the procedure: https://www.youtube.com/watch?v=3kYPjIHt8Lc

Wel. As you can see in the video. His downloaded file is a .PKG file. not a zip file after extraction. This is the issue. When i extract the file for my tv. i dont get a .pkg but again a .zip with multiple files in there.

I have also contacted nick and sad enough no clear anwser from them only suggested download from sony site which i end up again with .zip firmware.

Are you sure you are getting the proper software? from what I see it was taken off 01/30/2022

If you mean the one in video then that is not my tv. My set is kd-65xg9505,. and all i can see is .zip on sony site for this model.. So yes i am downloading the right firmware but that is not .pkg.

Ok, did you do this, when you see that second zip file, that is the one you want to put on your thumb drive, try that it should work.

Oh mate.. think of anything possible doing with that file and i have done that. 1st file. 2nd file. even 2nd file extracted, renamed, i have tried more than 100 times with 10 different usb sticks in different ways.. pfff. non helped. .pkg is the only way for it to work same like a windows bootle usb/disk can start the setup. putting extraced windows or iso or .zip will never boot for setup..

.zip work only when the tv is working and you want to update its firmware then you access it with the tv menu and run it..

It will never start the update from a usb port on its own.

Well hell if I know, that's a strange one, the procedure is there: https://www.sony.co.uk/electronics/s...tware/00267389

If Nick couldn't help you then I doubt any one can, he knows sonys from front to back.

wel. he just did not provided the firmware. otherwise there is no further issue with the tv..
