Will I need to unsold the eeprom? or can it be done in-circuit? -
Found, thanks
If I want to test or re-write the eeprom, what tools do I need ?
Any model to rate?
I need the TV program tooLeave a comment:

Thank you very much for the explanations, I will look after the C7144
With the motherboard plugged in:
The C7510 gives 5.11v
The C7505 gives 0.0v
Only, if I press the On button on the TV, the speakers start to crackle
And the voltage goes to 3.2v
I wanted to repeat the same operation and it didn't work:
The C7510 still stays at 5.11v
But the C7505 stays at 0.0v
So sometimes this C7505 is powered, sometimes it is not.
