Any chance this SNES can be saved without replacing the PPU?

First noticed, that David Crane’s Amazing Tennis glitches out and crashes the console.
After running the burn-in test these are the results:
MPY 8x8 FAIL
Also tested with F-Zero and while the the graphics renders correctly, the car becomes uncontrollable, smashes into the side of the track and i lose the race.
My questions:

  • are there any tutorials on how to replace the faulty chip?
  • can just a reflow fix the problem?
  • which chip exactly needs to be replaced?

Thank you
