Ok, thank you a lot, I will try it today !
Could you please explain to me what are in each memory IC1604/25Q40 , IC1603/25Q80 and 24512 Flash ?
Do you know what's going on with the 25Q40 ? Why is it corrupted ?
How do you make this magic ?
Do you have a kind of section memory decoder ? What is this program ? Homemade or Manufacturer tool ?
I keep you informed as soon as possible.

EDIT : I program 25Q40 with the fix. The TV are OK but I already have the vertical strip...
An idea for the strip problem ??...
