Repair rooba 775 error 5

I have this irobot 775 for 4 years.
I found the battery faulty and it gave me error 5.
I replaced the wheel module and it gave me the same error.
Once opened I found the faulty motor driver q59 and r96.
Changed driver and resistance no longer gives the error but the wheel remains still and always turns. If I push the reset button it turns to the other direction. You can help me?
as it turns, the anti-jamming indicator light turns on and off.
Has such a thing happened to you? what should i check on pcb?
