I seriously doubt it. It would be far more likely that some components somewhere are worn out or faulty.
Possibly it could have something to do with the settings, but I don't see how that could be true unless it was set wrong from the factory or someone has been in the settings and put something wrong. Normally it's setup correctly when it leaves the factory and the end-user doesn't have to mess with it.
It can be tempting to just try replacing a big IC because it seems like an easy thing to try, but it's very rarely the actual cause of failure in things like this.
When I have a big, difficult project like this, comparing voltages from the schematics is the number 1 way I make progress.
Doing this stuff can be really hard, and even after many years there are still some repairs I haven't figured out yet. It just be like that.
