Have you tried to reset the 540? With the unit turned off. Open the Battery cover and take a paper clip. There is a small hole above the batteries with the reset button. press the paper clip into the hole and press for a couple seconds. Try to turn unit on. See if that helps.
Many thanks but already do this, removing battery and reset more and more time, but doesnt power on.
Another idéa?

Have you tried to re flash the memory again? It would seem that the issue started with that failed attempt.
Sending the unit back to TAG Heuer in Switzerland is the safest thing to do if you get frustrated.

You can make a factory reset.
turn off the unit, remove the batteries, disconnect the charger.
Pull the rubber cover, connect two pins (such as a screwdriver or paper clip) NOTE: ONLY THESE TWO PINS!
work?

I know this is an old topic, but I successfully recovered from exactly the same problem. See my post here: https://timingguys.com/topic/5...8#597764686490562328
In short, you must use a real serial port on an old PC, not a USB-RS232 adaptor.
thank you for sharing 
I tried connecting these 2 pins for 10 seconds, but it doesn´t work for me. btw have a nice week
