Anyone Got any idea of the difference of the 3 Variants of the TNA Thomas’ Chip?

Motherboard instead of chip*
I recently received my 2 TNA Thomases, they are REALLY tiresome to repair, Hence why I haven’t been active in BPTs a lot recently. But that got me thinking, What’s the difference between all 3 variant’s Motherboards
I honestly don’t have any idea but if anyone here has one of the UK or US variants, could you please take a picture of the motherboard?
Thanks!

Have you looked Custom Trackmastees videos? I remember he repaired a UK and JP Talking Thomas (in the videos can be seen the soundchip) before, idk if also repaired the US version.

He repaired the US, he only fixed a UK James from the UK range, Thanks Kirby

Found the difference… it’s the black chip inside a TNA that holds the voice clips

Do both the UK and US PCBs have a switch that changes the voice to Thomas', James' or Percy's (from what I've heard), or is it just for the US releases?

Its only for the US Percy and James, they have the same boards but when you trigger a piece and hold something it will trigger the latter Character
