[NTLK] eMate 300 Infrared Repair

[Victor Rehorst]

I do, However, the IR hardware is neatly enclosed in a metal shroud - 
perhaps extra shielding, because it's right next to the power supply 
circuit?

Peeking underneath, there's two IR LED blasters, an IR receiver, some 
SMT passives, and at least one IC - can't make out the markings though, 
but there's a decent chance that it's an LT1328 IrDA/ASK receiver IC.

Later tonight I'll be able to desolder the shroud and take a good photo.
