It's better to tell us the setup codes that you tried (especially any in which one or more buttons worked) by setup code number rather than by brand.

I expect the reason learning failed is because the learning memory is full, not because of anything strange about these signals.

I don't have info on TV/0128.

I'm wondering whether the power code that worked is really coming from the setup code. Might you have learned that code before the learning memory was full?
