To bring this to an end, tv is working again, changing the BAL Board was the solution.

Re: SONY BAL BOARD Reset? 1-881-636-22
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?...Leave a comment:

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.

Re: SONY BAL BOARD Reset? 1-881-636-22
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?Leave a comment:

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

Re: Sony kdl-46ex706
have changed the 2pcs 16V 100µf on the bal board now as their ESR was a bit to high, seems to work at the moment...
i guess i will change all the caps on the bal board later...Leave a comment:
