There is another way.
You can try swapping the memory chips.
To do this, you need to cut two wires. The sections are marked in yellow.
And solder the two wires as marked in red.
At the same time, the microcircuits will swap and if the replacement ones are in good order, then the computer can work.
And then you will need to run a memory test, find and replace defective microcircuits.
