I have a:
PS2 V.16
SCPH-79001a
motherboard: GH-061-12
Matrix Infinity Green Dot
I am tying to get my Matrix Infinity green dot to work in this system. I have literaly installed this chip around 5 times in brand new systems before returning them to the store, getting my money back, and then going to another store to start the process all over again. I installed the chip according to this diagram :
I plug the power in and the composite a/v cable in and the red power light turns on. I press the power button and it turns green, then the screen flickers as it would if the system had just been turned on even wthout a chip, but then remains black and the disc stops spinning after a moment.
I am stumped and would be very appreciative if anyone has any feedback... thanks
Have you flashed youir chip? I believe the Green Dots are shipped unflashed.
But from what you say about your power up, it sounds like you either have a short on the bios wires or a wire in the wrong spot or a wire that is not connected. Double check your install. I have been modding for years and even sometimes I forget something.
I did check all the wires again with a voltage meter and each contact is getting power to it, the only thing is i don't know what the correct voltage for each of the contacts should be (except for the power), so that doesn't rule out a short completely, (the extrememly close contacts for "B,H,I" could be a problem spot, but i am very apprehensive to mess with those contacts because of how extremely difficult they were to solder, and teh method i used should have ensured that they wouldn't be touching). If teh green dot is not flashed, how would i flash it if the playstation isn't booting? Though, i do not think it could be that because i had a chip that i took out of a v15 PS that i knew was working fine and had used that one originally in the v16. I am stumped.
Take ohm readings in the bios area. Check between each pad and where you soldered the wire. You should get either "infinity" or a reading higher than 0.5 ohms. If you see 0.5 or less ohms, you have a short. None of the solder points should be shorted to the pad on either side of it. Start there. The bios is what tells the system to boot. If you are not booting, the bios should be the first place to look.
B, H, I Ohm from the chip to the "via" or little circle pad. You should get 0.5 ohms or read a short. If you have a good set of leads, you should be able to touch the chip pad and the point of the via without actually touching the wire you've soldered. If your leads are too thick to touch the via without touching the wire, use a dremel and grind down the lead to a fine point. then try again.
If you still can't figure it out, feel free to PM me
you were right, it was one of the bios points on the borad... after after trying to reconnect them i realized how much of a pain in the balls it is to get those soldered on correctly, and basically i just don't have the patience any longer, i guess i am just not skilled enough....so i was wondering if you or anyone knows of any alternate bios points on the board, if not if you have any technique that would allow me an easier time in making good, strong contacts to the board.
You're very welcome. That's what we're here for...
For a good solid connection, First, tin your wires. This means solder both ends of the wire making it silver. Also tin the area or pad that you will be soldering to. The bios pads or points and the pads or points on the chip. This will greatly improve your connection. Use a little flux on the pads and the wire to allow the solder to "flow" better. When you're done, you should have a nice and shiny solder joint.
Take your time! Do not rush your install. I think the first console I modded was my PS2. It took me 3 hours to do. But I didn't rush it and made sure I had everything right. My wires were, how shall I say, a huge rats nest, but it worked on the first try.
