SONY BAL BOARD Reset? 1-881-636-22

[bf350]

HI,

my BAL board 1-881-636-22 is defective so i decided to buy a used one from an other tv set.

Sony tells in the service manual the 2010 Model BAL board is generic so just the software needs to be updated.

well i formated a 8GB stick FAT32, copied the firmware on it, plugged it in but the tv set refuses to update the software.
it just flashes 5 times the red led which indicates a Panel ID NVM Error error which is clear to me.

so my questions are:

can i force a software update?
can i reset the BAL Board?
can i cange the panel ID somewhere else?


No way to get a used BAL borad working in another TV Set?

thanks in advance and best regards,

Replacement BAL boards will now be stocked with basic software. Once the replacement board is installed in the unit, the most current software is to be installed using a USB storage device containing the necessary software downloaded from the ASC support web page.

can i get that basic software somewhere and can i flash it to my BAL board?

what does the tv screen indicate, if anything, when you power up with the usb plugged in? What folder did you use on the usb?
Have you tried entering the service menu?

have used a 16GB and a 8GB usb fat 32 stick which indicat access by a flashing led on the stick - well at power up the led on the USB isnt flashing. but the same also on the original bal board - when the os is up it searches the usb stick and displays that the is firmware on it...

tried also to get into the service menu - tries to power up and then ends by flashing the red led on the tv set for 5 times.

I guess we are going to do the "tooth pull" on this. You need provide some history on the set and what you have done to get to where you are.

My guess from my quick read is that your set has a tcon issue (blown fuse) or possibly a bad panel causing an issue.... again just from a quick read.

thanks for helping guys,

well on this set it is a 100% BAL Board issue regarding the old BAL Board.

the "new used" one just refuses to take the SW and refuses to start up.

My question is in this threads are:

are the BAL boards interchangeable when they have the same SONY Part number but used in another TV Set wich another LCD Size.

has anybody ever successfully installed an used BAL Board?

how can i force a USB FW upgrade even when the TV remains black?

thanks in advance
