Need Some Help Troubleshooting
Sup guys, I could use some help figuring out what I've messed up inside my ps2.
I ordered a chip, and in preparation decided to do the romeo mod because my console was a V9. Being a complete noob to the insides of the ps2, and not all that gifted with a soldering iron, it took me awhile but I got it done. Pin 17 of the LA6508 chip is isolated from the board, and soldered to the +5 via, is getting power and seems to be working fine.
After reassembling the unit, I tested it out with an original Devil May Cry 3 (chip is still on order), and the unit emitted a mechanical noise akin to gears slipping which almost made my heart stop in my chest. BUT, it went on to load the game with the exact same loading time, with no delays, skips, or foul ups. I played a couple minutes to test; and the noise was intermittant, but the game always worked beautifully. I saw a post on another board about a guy who had the same noise, but his machine didn't work at all, who corrected it by just simply redoing the mod. So that's what I did.
I used another length of 20awg wire with 60/40 .032 resin core solder, only this time I ran the wire down and around the laser cable as I saw in the "instructions" (I use the term loosely, a single "after" picture is all I can find for the v9) that are on the net. I hadn't done that the first time thinking it wouldn't matter. The only difference is that the only good install diagrams I could find were of a v10, and the v9 has two chips close to that slot on the underside of the board. So, I ran it close to those and back up onto the topside, clipped and stripped the excess wire, and soldered the new run to the via.
Now, the noise is still there but happens MUCH less frequently, and always at the same sections. If I was to reset the machine I would hear it initially, then when the unit gets to the dolby digital screen I would hear it again for a split second, and also at the game over screen. I tried loading a couple levels, my saved game, and playing for a couple minutes and it didn't reoccur during normal loading. That is an improvement over the original install, but I'd like to get it solved entirely.
Okay, now, on to what I may have done to screw it up. When I was reconnecting the laser assembly cable the first time the pressure from my inserting the cable caused the assembly to move; and I heard the gear slipping noise. There's also the likelyhood of a bad solder joint; since I have read about that causing the noise. But I don't know how likely that is since in all the other cases I have read about the ps2 just didn't work, and it would emit that noise. But mine seems to work perfectly. Based on what I've described I hope someone can give me a couple suggestions as to other possible causes of this, and hopefully some solutions.
Thanks for any help you guys can give, and hopefully the actual chip install will go smoother.
