Atari STE v1 BOOSTER ic2 burned

[valfac]

Now I have one resistor of 470R and a capacitor. I understand that I need remplace the resitor for another with a value of 68R and desolder the cap, is correct it? :D

On the other hand, yes I have sim with 9 ics, then I should desolder the parity ic..

Internal blitter machine needs mods to booster...

Correct.

Yes, Parity simms malfunction in STE's.

Capacitor retired and resistor changed for a SMD 100R (less value I have in SMS 0805), and now the Blitter works well! :D

Official diagnostic cartridge Blitter test is PASS!

Now is time of desolder the ram parity,s ic.

Thanks for your great help! @exxos

Congratulations! That's a nicely performed step by step implementation of likely solutions resulting in success :D
