Hi friends
I hope everyone is well and wishes everyone good health.
Following the VAS 5054 Rework by replacing the components, the VAS 5054 no longer works, the blue indicator does not light up any more and the laptop no longer sees it.

After having carried out the first test the VAS 5054 did not work any more, more blue led nor recognized on laptop. Following the test to understand why it did not work anymore i noticed that the chip marked "RS3M" does not receive 12V it is at 0.45V ??? it exceeds my low capacity amateur electrician, I do not understand ?
I tested the blue led it works without problem, I reassembled the LTZF chip and returned the 78L05 always the same, then the SM8S36A the same still nothing, I am lost![doh]( "doh")
Any help will be welcome.
Thank you in advance.
