(I waiting about 20 min, put all power off) then, try to go to turn the machine on it acts like it's going to fire up but as soon as it reaches the "version 3.04" screen it shut down completely.

It's most likely a fried main board. You can try unplugging the head cables and then try powering on to see if the head is maybe shorting out and causing the board to reset but other than that it's usually going to be the board itself.

If so
I need to buy a new board and power supply. Do you have a link to tell me which board I need to buy?
thank you very much
 
I have had a power supply go on a 1624. It was by no fault of the printer. I would urn the machine on and it would die at almost the same spot every time. I went through all of my normal diagnostics and noting. Then I realized that if I put the paper handle in the up position, powered the machine, did not let it initialize, it would run longer but still fail. Long story short. A roach crawled behind the power supply board and made contact. Created a short. I replaced the board and al was new. I would unplug machine and let it discharge. Pull the power supply board inspect the back. you never know.

You can test the power supply if you know how to use a voltmeter. In my experience it's usually the main board though.
 
When a printer does not turn on it is because the mainboard transistor is burned out and for protection it does not allow the printer to turn on. if you replace this transistor you can re use the old board.
of course changing the mainboard you will solve the problem .. but first you must understand what caused the short circuit. and in many cases it is the head.
Could you send me a picture of the transistor in you mainboard to show you how to check each transistor..
