Problem with Stealth IV chip for mini ps1...
Just installed the Stealth IV mod chip (6 wire). I just bought this new a few days ago. Figured it would be good and easy to throw this chip in (I've installed chips in a couple old model ps1's and even ps2, and so I do have soldering experience with such things).
But this was my first chip installed on the mini ps1, and this one was mine, wasn't doing this for somebody else for a change. This is the 101 ntsc version.
Anyhow, all the connections seemed good and tight, so I just lightly put the big metal piece back on, then put the laser unit back on. No obvious signs of problems. I was going to screw the top plastic half (the lid) back on once I knew the installation was OK.
I plugged it in, and it turned on, the splash screen came up (had an original psx disc in for testing) and I thought things were all good. But after the splash screen, I was taken to the memory card screen because the disc never started to spin, and the laser never turned on! DAMN!
Now, unlike the older psx, the ribbon connector from the laser was a pain to remove because it had like a sticky glue inside the connector. But I was able to get it out in one piece, no obvious damage. The other plug came out easy.
So I can't possibly imagine that I damaged the laser.
Next, I figured maybe one of the connections were bad, so I desoldered everything and tried everything all over again, being extra careful. Again, everything went well, I laid the metal heat sheild on lightly, put the laser unit back on, hit the power button......
Then NOTHING! No power light, everything was dead!
Can somebody please tell me what could of possibly gone wrong here? The board is in tact.
I didn't hold the iron on any pad for more than a second or two (and I'm using a nice low 15 watt iron), so I can't imagine I fried something that way.
Lastly, I removed the wires from the chip (leaving them on the board) and tried again to see if maybe the chip caused the problem, but I got the same result.
Any help would be greatly appreciated. I actually paid good $$ for this console in new condition. I've never had anything nearly this bad happen before on any other of the mods I've done.
I would also love to see a motherboard layout for this unit, seeing what areas are related to what function so that I can mess around with trying to fix it. Or maybe you guys could tell me where the problem might be.
But as of now, I don't even know where to start.
Thanks, this is my first post here, sorry it is so long, but I want to explain thoroughly!
