"cold solder joints on board headers reflowed" I see people talking alot about this when working with WG6100s. What does this term mean and where is it located a picture with a arrow point say here idiot would be great! Im not easily offened. I'm making 2012 the year of learning diagonistic and repair and not purchasing!
Thanks

Basically what this means is is to re-solder it. heat it up with a soldering iron and add new solder to it.
"A cold solder joint is typically a joint where maybe the soldering iron wasn't hot enough or enough heat wasn't applied for the solder to melt and really form a good bond"

This is a cold solder joint

What they mean is this:

There are connectors that plug into the 6100 chassis. The rows of pins that they connect to are called "headers" by some. Obviously they are referring to the chassis as the "board". So, this tells you they are referring to the pins on the boards. Now, these pins are mounted on the parts side, and are soldered underneath. Sometimes the solder to these pins becomes heated during use over the years and when they again cool, the (now "cold") solder will sometimes not be fully adhered to the pin. This causes a poor connection and will not always work as intended. They call this a "cold solder joint". To fix this issue, most people just put a hot soldering iron on the solder to melt it, then wait for it to "reflow" back onto the pin. What more experience techs do is completely remove the old solder from each pin and put new solder in its place - one pin at a time. It is recommended on the K6100 to do this to all the pins regardless of whether they look like they have cold solder or not...
 
I think this may be one of those thing you need to watch someone do then try yourself, but I get what people are saying thanks for your time. I don't know if anyone has done this but someone shooting a video of simple diagnositc, Like measuring all voltages, or doing a cap kit of a monior or showing how or the materials needed for soldering. I would pay for a dvd like or donate to a link if someone spent the time. I'm a very visual learner and if I can see and re-watch a producer I can usally pick it up quickly. Any thoughts? or has this been done before? Thanks DKJR
