Repair?

[Yosikuma]

As someone hopelessly klutzy and in no ways handy, is there another method outside of self repair that I can go through in order to replace the TIA on my six switch?

Agreed

But no need to be a top handyman to do that ! Just a screwdriver needed. The most difficult part imho is to find a new TIA
