820-3115-b - weird graphics problem

[2informaticos]

Did you remove R2415?
Do not listen the ones say to remove L2406.
Belive me, is more easy to remove the resistor!
Don't forget to put it back, once process is completed.

To disable GPU power supply, remove R8904/11 (at least one).

I had already tried it before posting yesterday after removing L2406 with the same resulting error,

Should I bother try again removing R2415 and R8904?~

( Also Im using the Diamond Programmer on windows 11machine ,you think this could be anything to do with the issue and is it worth trying this on a win 10 machine?

Removing R2415, or L2406 has the same effect.

I don't recommend to use Windows 11 for anything else than entertainment.
I can confirm Diamond software and Lattice programmer work under Windows 10 x64.
