1. I have several questions for anyone that's willing to listen. I had my version 5 (GH-015 motherboard) PS2 machine powered up and had a bad Sony Dualshock II controller attached to it. I was attempting to clean the controller's insides with rubbing alcohol and a cotton swab while it was attached (foolish, I know).
After my attempt at cleaning the controller, I discovered that the PS2 was not recognizing ANY kind of memory cards in either port (Sony and 3rd party). After posting several times about this problem and after reading countless posts in this forum, I decided to gather some courage and disassemble my PS2 down to the motherboard. I have a version 5 PS2. This particular motherboard, if I'm not mistaken, has fuses from PS1 to PS13. All of the fuses read virtually zero resistance/full continuity except for PS7, which is marked with ?S7 135? on it. From what I know, this fuse controls vibration function and any type of infrared device that?s attached to the controller port (I guess it controls memory card ports too?). I'm sure it's blown, but I have no clue how to detach it from the motherboard and no clue where to find a replacement for it.
I have very basic soldering skills and would love to fix this problem myself, being that I'm NOT paying Sony another dime (out of warranty). However, the leads from the PS7 fuse, which I guess is either called a surface mount protection fuse (or is it a picofuse? is that the same thing?), seem much too small to be touched by the tip of a soldering iron for successful removal of the fuse from the board. I?m not even sure at what wattage rating the soldering iron should be (15 watts? 30 watts?). Before you guys tell me that I?m not ready for this kind of project yet, please read further.
Is there anyway someone can show me, either via text or pictures (that would be a blessing!), how to replace this PS7 fuse? Where would I want to aim the soldering iron tip? What gauge solder do I need to use? Do I need flux? Lastly, where can I find a replacement fuse for the PS7? Does Radio Shack have an equivalent fuse (I had no luck on their website)? If I have no choice, then I?ll have to order it from www.videogamerepair.com (nothing personal, I?m just losing patience).
2. What is the rating of the PS7 fuse?
3. What kind of lubricant would you guys recommend to use on the two laser assembly guide rails? I want it to have smooth and proper moving function.
4. Upon reassembling the unit, do I need to apply thermal grease/compound/putty anywhere? Do any of the chips need to be coated?
Please help me out. I would really, really appreciate any help.
Thank you so much for reading this winded request!
