She used Chongs, and it got more amusing when I compared what she'd used against the schematic. The values were fairly random. For example a 4700 where the schematic specified a 1500, and a 25V instead of a 35V. At first I assumed she must have bought a kit, but it looks llke she just went "Right, so I need a big one, two smaller ones and then a really little one". Or maybe she typed in Samsung TV repair kit and got one for a 32" LCD or something. ???
To her credit she did at least manage to put them in the right way round.
To update, I've think I've actually managed to get the PSU working! The regulator for the 18V_Amp is shorted which is what was making all the heat. By jumpering PS_ON and VS_ON I managed to get Vs voltage up. Now I've just got to find out why the logic board isn't giving the VS_ON signal itself. Hope the lady hasn't fried it.

decided I might be able to salvage something out of it anyway and took it home. I wasn't quite prepared for what I'd find inside.
Damn, that's rough! But you got a single-layer board, thick traces.. easy fix.
Problem with the internet, every man and his dog with a computer has likely heard stories of "them darn capacitors" and can buy an 80 watt (bigger is better, right?) soldering iron from the local hardware store for $5.
Still, hopefully some of these people will learn something....
