If it is misalignment, then new ones would not perform any better than the old ones.
If blocking the eyes, still allows the door to close, that is a serious issue.
There is no way to bypass or disable the eyes and the door opener work.
They may not deactivate when blocking, but you cannot get around them in any way. They work on a frequency signal and there is no way to simulate the operation to fool the opener.
I think in your case, if that was happening, that the eyes had failed already but instead of failing in the deactivated mode, they failed activated and now maybe they have completely wiped out internally.
The holding of the wall button works ONLY to close the door when the safety system fails, there is no other purpose.
The safety eyes are the issue in one way or the other.
