One of my first C64C Ebay purchases was a complete "working" C64C with a 1541II and a number of games.
When I got it, it was great but it just looked washed out. It wasn't until I tried a few more games that I realized that something was actually wrong.

To the Internet
. . .
Everything we need these days is a quick search on Google. I found two fantastic site right away.
Ray Carlsen's amazing website : http://personalpages.tds.net/~rcarlsen/
Pictorial C64 Fault Guide website : https://derbian.webs.com/c64diag/
The first thing I did was order a C64 power supply from Ray. I really did not want to damage my C64 any further.
The second thing I did was buy a cheap desoldering gun and some DIP sockets. Get the right tools and do it right the first time.
The last thing I did was get a couple of colour RAM chips.
. . .
So the process was pretty simple.
Add a little solder and use the desoldering gun to free all of the pins
Use some solder wick to remove the remaining solder with your soldering iron.
Solder on a DIP socket ( always put in a socket . . . always ).
Push the chip in.
Behold . . . real colour . . .
