Crystal Chip install/GH-040-72
Crystal Chip install/GH-040-72 –
Well I go to open my slim pstwo to install my new crystal chip... I disassemble my pstwo to find out what v14 motherboard I have. To my suprise I have a GH-040-72, and there are no instruction manuals for this motherboard. Am I just SOL or is there another motherboard install that I can use to put in my crystal chip?
Did some googling and found out that the schematic for GH-036-51 could possibly be the same for my motherboard. Can someone confirm this before I start soldering?
Well after printing out a picture I took of my motherboard and printing out the GH-036-51 install diagrams... I compared the solderpoints and it came back to be identical. I chose to move forward with the install
After a couple hours of soldering, I was finished. Picture is below.
I am also having a problem upgrading to firmware 32 hacked. I was getting the black screen. I tried it using recovery mode, but that still didn't work. I had to put firmware 29 on there. I'll post these results in the firmware thread to give feedback.
Ok, here's something interesting that is happening to my pstwo since after the install of the chip. After the pstwo is on for a while, maybe 20 min and it starts to get warm on the CPU side, if I shut down the pstwo and remove the AC power plug from the back of the pstwo and replace it. It won't power back on. I have to wait like 10 or 15 min for it to cool down then the red standby light will light up and I can power on the pstwo.
While repacking the PS2, perhaps you've forgotten to plug a fan ?
That's what I thought, but I reopened it and checked it and the fan is spinning.
That's a very serious issue, I would not suggest running your PS2 for any length of time until you resolve it. As Yoc said, check your fans. Also make sure you aren't blocking the air intakes. Finally, be sure you insulate the chip with tape or something to ensure it isn't shorting on the metal cover. Perhaps when the board heats up it expands a bit and makes contact...
I have checked and rechecked everything. I can't understand why this is happening. The pstwo will play fine if left on, but as soon as I disconnect the power it has to wait before the red led light will light up again. could this having anything to do with the fact I couldn't find schemactics for my specific motherboard? I had to use the GH-036-51 install diagrams.
Could the modchip be causing this at all?
Secondly, if so... what wires should I be looking at to make sure I have soldered them correctly.
I currently have the motherboard sitting outside of the plastic casing so its well ventilated. The Heat sink is not hot... just barely warm. So I am not sure this is a heat issue. Like I mentioned, if I power on the pstwo and leave it on for a bit, I can turn it off (red LED/standby) and the led will stay red. I can then power it back on, no problems. But after being on for a few min, if I unplug the power and plug it back in... the standby LED will not liight up... I can leave the AC adapter plugged in and after a few min (5 or so), the red LED light will come on all by itself, then I can power it back on.
Ok, I figured out what was causing the problem. It was my neofix chip. I disconnected the V5 connection on the chip and it powers on fine. So my next question is: Is this normal? I used my multimeter on the mobo point that goes to V5 and it's actually giving out close to V8.5. I think that might be too much for the neofix chip. Is that also normal to hook up a V5 to an point that is giving V8.5? Should I look for a solder point that is giving out closer to V5 volts?
