Re: Toshiba 49V6863DG firmware request
Thank you @yokoono
At the end I used upgrade files I had in hand for the Hitachi 49HK6000 which is exactly (including the subw amp) the same as my Tosh, and solved the problem.
Of coarse it came in as a Tosh, and leaves as a Hitachi.
Is it possible to change the boot logo splash-screen?
Good to have the files you uploaded for me, specially the nand dump.
Thanks againLeave a comment:

Toshiba 49V6863DG firmware request
Hi,
The above set boots with logo, then black screen with B/L on and continues with the alternate red/green flash.
An upgrade file would be welcomed before desoldering the flash spi/nand chips.

Hello there,
I have followed your thread with great interest.
I having the same problem with my Sharp 40" TV.
The TV runs for a few minutes, then turn off,the triangle blinks 2 slow and 1 fast.
I measured this device PC7703 with my Fluke and with reference to the other optocoupler and I didn't find any differences.
Do you remember if your faulty op/co was shorted or shows different measure.
Please advise
Regards
