Thanks Wolfey and everyone else whom have contributed to this thread.
I bought a Weller 35watt iron and a pencil tip for it.
Picked my worst GS unit and now the little bugger has been running at 1200 for the past couple errors w/o a HW error (yet).
I did notice that the heatsink wasn't tightened down properly thus one of the GS chips wasn't making full contact with the thermal pad. That might have something to do with the HW errors as has been mentioned before.
I'm going to begin modding my other GS units starting tomorrow ... not today.
It was a nerve-wracking experience for me. But I have one under my belt now. I at least know the general idea now.
I feel you
my first one was also quite nerve wrecking !
I was freaking out, man.
I couldn't get the original resistor off so I YouTube'd how to get the fuggers off ... lol
Just switched sides heating up the solder and pressed it away with the tip.
Then mounting the axial resistor was entertaining ... solder didn't want to stick to the outer-most pad worth a #%^! so I dropped a ball of solder on there and put the axial over top of it resting on it and melted the ball of solder and pressed the axial down into it. That worked.
Then I got an eraser and rubbed off the contact of the R52 pad (noticed the clean contact transferred solder beautifully on my throw-away motherboard) and that wasn't much of a pain in the but, just seeing stuff without a magnifying glass kinda sucked donkey. Fortunately I'm near-sighted ... never thought I'd be happy to be near-sighted -- ever.
So I had it all good to go and noticed the heatsink was gonna make contact with the axial so guess what ... got to re-do R52 because I had to cut the axial resistor wire more. Didn't really want to be electrifying the heatsink, of all things.
It was a BIG learning experience.
I see you had exactly the same problems as me.
solder was very hard to stick on the outer pad, so I picked up little balls of solder from out of my sponge put it on the pad then heated it with
the iron to make it stick and then take the resistor and melt the tin again so that the resistor goes into the little solder ball.
I also had a hard time getting the smd's off somehow they just did not want to desolder but found a way.
